Nokta Impact information

Lots of data to soak in and absorb, you did an excellent job, in fact above and beyond. Some posts have to re-read.

I too will be curious when folks start reporting their experiences/finds as well.

Thanks TNNS.

You are welcome.

Now,,some folks may be thinking,,ole sharpshooter is talking out his you know what.

I will remind folks here,,Mr Dankowski tested a Nokta Gold unit I think,,and based on his testing it was within 4percent of Deus or Xp Gold Maxx power(I can't remember which one) as far as separation/unmasking,,and remember this unit he tested was a 19khz unit.

Impact is a 20khz unit as well as a different detector,,,so think about this.

Now,,I don't know how in the world Mr Dankowski arrived at his conclusion,,but he is a very capable detectorist IMO,,and it seems engineer to boot.

Also,,remember many detectors may be seeing more than we realize,,but it is intelligent(more intelligent) reporting that counts.

The Impact appears to be on par, top tier.

It certainly does.

But a person with just a few days running one,,,they might just discount it.
Performance is there,,I've seen it in the wild a hunting.

Folks may hear the term here high tone squeakers used in conjunction with Impact.
Yep,,you will hear these when hunting in the iron and nails.
So far,,,smaller coil seems to provide more of these vs the stock coil in similar sites. Stock coil obviously on average will have more iron/nails under coil at any one time,,,so the tone provided does get dragged down (moves closer to iron tone),,but still very audible/recognizable.

Also on thinner finds,,and smaller Impact is good.

These smaller finds many times can be exposed with needing super extreme coil position to hear tone,,coil height very little if any room for error.

In the site today,,,was also impressed with how the overload tone worked,, or should I say it didn't get set hardly at all,,,but this site has a ton of mixed sized ferrous materials.

Disc level 3 seems to give superb performance separation and unmasking wise,,,this is the default setting I think for all modes except Deep.

Folks will notice,,in iron and nail pits,,20khz runs smoother on the iron,,,switching to 14khz impact not as smooth and nail falses more common on average.

Using 5khz in such a site,,,detector would have to hit a wide gap to take advantage of additional depth(higher conductors),,,you run 5khz mostly in sites like I have described,,,you are IMO wasting your time,,doing the Impact detector an injustice.

So folks understand,,I can make finds behind Deus using Impact stock coil,,but I can take Deus and make finds behind Impact.

Strange sounding eh??

Coil sizes/ shapes here come into play,,and audio reported by Deus on some of the more challenged targets.

Smaller coil used on Impact,,,folks need to remember there will be targets (shallower) Impact with stock coil will see the smallest coil won't.
And vice versa?
Depends on each and every detecting scenario,,,and this is related to the fields in the coils and saturation,,,with different affects depending on exact detecting scenario.

Deus users hunting with Impact users,,,they will have a ball I think,,in comparing signals and hunting in general.

To set the record straight here,,,Impact detector is NOT a Racer 1 or 2 detector with chrome!!
Rest assured.
 
More data...

A 5 hour meeting with Impact wearing stock coil.

Across the road from site yesterday,,,I have found 0 coins in this site in the past using any and all detectors. Lots of iron and nails,,very old 1750s -1900s for activity.

I would rate this hunt today a relic hunt,,but make no mistake,,I would take a coin if I could find one.lol

Impact run in 20khz exclusively,,disc set to default level 3, DI99 Max gain of 99.
Detector purred like a kitten all day,,,never did mitigate for emi Even once,,ran on channel 3, imask level 0.

Again some very good performance,,will post pic later.

Relic hunters,,,this baby will hunt in nails and iron,,both smaller and bigger.

Had the ole Deus with 9" coil along for the ride,,and some head to heads performed.

Actually tried to alternate using one to find a find,,then cross check,,and so on.

Not all targets found with Impact were cross checked.

These 2 detectors both fine units.

They do speak different languages though,,,and the actual targets found,,and amount of masking will alter Deus language moreso.

I can tell generally for example when I find a target with Impact how it will sound on Deus.

Impact by design is a more full tone machine,,both using in cleaner ground as well as in areas riddled with iron and nails.

So what did I see today,,when comparing detectors over targets.

Each and every target found using one detector,,the other would detect also.

Sometimes one detector would be more forgiving over target (from a tone/audio) intelligence perspective when moving coil around and over suspect target,,and some times the other detector would be more forgiving.

Where the Impact shines the most on masked nonferrous targets,,,is when it give a steady lower ID but a sorta wishy washy tone,,,still very audible for user,,the targets the Impact reports like this,,,Deus likes to give the almost iron tone,,,very murmured growl.

If Impact's meter windshield wipes while sweeping a nonferrous target,,,Deus on these seems to give more textbook signal (Deus users) here will know what I'm talking about.

A note here for Deus users,,and I have mentioned this before in other places.
Reactivity setting 3 hunting in sites like talked about here,,moreso your friend from an unmasking/separation standpoint using 11" coil,,but using 9" coil,,reactivity 2 can be used with more controlled coil sweep and get a signal with longer duration vs using reactivity 3. Some signals using reactivity 3 and 4,, be on guard for overly short hits.

Some folks may be wondering how well do the Impact and Deus play together,,interference wise??

Now remember I was by myself,,so I had to improvise a bit,,,and I didn't have Impact wireless headphones with me,,did have Deus wireless though.
Overall they seem to play together well,,,if anything from an audible standpoint,,Deus in 18khz,,,I could tell distance here shorter between detectors to get some interference ,,vs Impact while in 20 khz.

A cold day,,but was very rewarding to me.
To be able to get more and more supporting data on the Impact.

Remember this site-- hard busted by me previously many times before.
IN the pic,,all nonferrous except the thing in top left (I dug it with thinking it was iron,,,had to verify)..top right thingy,,and the 2 nails.
The bent nail,,,I can't Belive how deep I hit it,,some folks may think this is a bad thing,,actually quite the reverse,,,Impact seems to be getting some good depth here,

The bigger item on the right side,,is lead I think,,,it was deep,,had to pull 2 nails out while digging,,this was a signal that sounded good,,but could have been confused with iron wrap signal if not careful.
Meter on it was really moving around,,and faster generally for a nonferrous.

Again,,I need to reinterate here,,what I like about Impact in sites like this,,,it will give high tone,,even if coil is out of position more,,and or sweep speed is a little too fast,,,then when you hone the coil over target,,with a heavily masked target,,big key is if your hear a lower than midtone tone,,,good indicator of nonferrous,,,if you hear only high tones when sweeping and meter is running quickly up and down reading wise,,,odds are suspect target is ferrous.

Another thing I like about Impact.
I can more easily use in a site,,with stock and smallest coils,,but moreso with smallest coil,,,take Impact and actually determine just how challenged a target is,,,,hunting in already pounded sites,,where Etrac/CTX runners have been,,,this being able to do what I'm talking about is grand.
This to me the way I see it,,ups my odds,,and I waste less time digging more unworthy targets. Granted a person after gold,,,this not such a grand scheme.

Wow those are some tiny targets there. When one pulls tiny targets like that

especially when they are deep, makes one feel pretty in sync with their machine and that they are running good settings.

Just like my avatar, that tiny target was near carrot length deep down, picked off w/deus custom settings.

So this Impact you speak of, looks to be quite promising.

Well,
Hunting in sites with loads of iron and nails,,,hard to set detector up wrong,,,Imask setting IMO does need to be 0 or 1 though,,,gain setting there is some wiggle room,,,disc at 3,,a person can rock and roll. Coil sweep speed/height does need to be managed well here,,especially if hard hunted previously.

My thoughts here,,taking an Impact or a Deus to an old site (virgin) with goal of digging all nonferrous detected,,,,a person might dig themselves to death. Literally!!!
You try to run a Etrac or CTX with medium or small coils in these kinds of sites,,painstaking,,and a lot of nonferrous finds will be left in the ground--Period!

Folks with bad hearing,,IMO Impact better choice vs Deus,,,Impact tones,,language easier to hear (volume wise).

And I am only speaking the truth here,,,not a promo or a hit job.

More data

A short hunt this morning,,coin hunt this time.

A house built in the 1940s,,I have hit this baby hard with White's V3i 10x12 SEF coil,,Etrac with 10x12" coil,,CTX with stock coil,,,Deus with both 9 and 11" coils.

In the pic,,,the coins shown not found at this site,,will talk about them here later,,the rest was found at this older house site.
The find in the top right beneath the rifle casing,,,a higher conductor,,air tested on CTX 12-40,,and the little nut also a high conductor.

The rifle casings I dug them,,found using 20khz, but using 5khz exposed them to be mid conductors,,they didn't pinpoint very big,,,don't know their orientation but could have been pointed down in the ground lengthwise.

The coins were found at my mother's home.
Right beside sidewalk (no iron in sidewalk and it is flush with top of ground),,a sidewalk I have swept many times with Etrac,,CTX, Deus and V3i detector,,,,none were wearing smaller coils (Deus 9" was used).

These coins about 5" deep,,notice the lower left,,,see the piece of wire,,,this was exhumed just off to the side of one of the coins,,,at first I thought I got fooled,,but resweep I detected con again and recovered.

This area very polluted,,and using iron vol really showed this,,even some ferrous was trying to set the detector with falses.

Notice the pull tab,,the only reason I dig it,,,I detected it REAL close to an overload signal,,,this was one of those CHALLENGED targets I keep referring to,,,and gave it shot just to see if I could get lucky.

Now,,here is what is going on I think with Impact,,,with some of my backtracking and being able to recover coins.

No head to heads were done btw today,,,but it seems Impact with smallest coil is giving me both tone and ID to boot,,,I think the other detectors when I hunted here with,,one of a few things happened.
Either there was no detection period
Or they were detected with a junk target ID,,lower ID reading.

If you will go back up in the long thread you will see where I comment about a target in my mother in law's yard,,,in a spot where I had swept with many detectors,,and all detected this find,,but gave an ID that would suggest lower conducive junk target,,but Impact gave super tone and great ID--turns out it was a high conductive coin.

The smallest coil used on Impact,,,a person can literally go back to any site that is polluted and they just might pull some more finds out.

I see a trend definitely with this detector and coil setup.

This older house site btw has quite a bit of modern trash around.

A real workhorse of a setup.

You know how you know when you feel confident with a detector and small coil??
When you go detecting. And the only thing you take is a detector with small coil attached and drive 15miles one way to hunt a site.

Says a bunch about my confidence here with this unit.
I do have some other worthy units and coils,,,but it seems they have trouble moreso in some of these spots on some of these sites.

Forget to say hunted in 20 kHz,,,3 phase power power poles about 40 ft away,, with one transformer about 80 ft,,and another about 40 ft.,,Impact purred like a kitten,,no interference noticed audibly.

More info.

Test garden data on 9" and 10" dime (dime could be as deep as 10.25")

I haven't talked a whole lot about deep mode.

So here goes.

Using deep mode,,coil,sweep speed needs to be controlled more vs not using deep modes.

The 9" dime,,using freqs 5 and 14khz,,,a strong signal,,,would dig every day of the week.
What about ID on this dime.

Using say DI99 with gain maxed to 99,,in 5khz,with a whopping signal,,but ID tends to go to the high side numbers wise( not on all sweeps but some),,tone is higher on all sweeps.
.
Remember my ground not the mildest,,2 bars indicated in minerlization meter.
This same 9" dime when I go to deep mode,,ID is practically spot on between sweeps.

So deep mode can be used to improve ID of deeper target.
And remember a person can have it already set up,,,just toggle and use to investigate suspect target.
Also deep mode using on the 9" deep dime,,some additional coil height above ground is allowed and detection is gotten,,as coil,height increases,,TID of dime may start to suffer though a bit.

Now on to the deeper dime,,,I made sure it was a solid 10" deep when I buried,,it may be a tad deeper.

Since my soil is reading 2 bars on the minerlization meter,,,this dime using deep mode reads as nonferrous,,one thing I notice though it reads a strong signal audio wise,,but the TID reads high in the iron range. Could this be a clue for a deeper nonferrous??

Now if Ingo to DI99 mode using 0 Imask,,0 disc,,if I flush this deeper dime,,I can get a high flash of tone on some sweeps.
In the wild detecting,,this what is happening here,,,would be obviously lower odds of locating,,but still possible.
Especially if some deeper coinage has already been located and dug.

DI99 mode for me,,,in my soil,,gets the nod for alerting me to the deepest detectable while using this detector.

Milder ground this could be different for me and other folks as well.

Btw,,a F75dst unit,,,I have swept this same dime,,actually both,,,the 9" dime didn't sound as good vs Impact using it and ID not as good as Impact especially with Impact in deep mode (night and day difference) and the 10" dime,,nothing but an iron tone with iron TID to boot.

Deus on the 9" dime does get,,but you don't know what is is by any ID.
Deus on the 10" dime,,,nothing Inwould dig,,sounds like the detector is over a deep nail. This trying all possible/reasonable settings changes. And both 9" and 11" coils.

You played a big part in my buying the Impact. Thank You! I was cosidering the XP Deus but the price of the Impact tipped the scales for me. A suggestion, could, would the company do a webinar so those that sign up can ask questions and see some online solutions to the various questions put forth. Could you ask them?

I can ask.
But in the future after some other folks purchase,,,there will be I think a good pool of people that can answer any question a Nokta Impact user will have or a person interested or contemplating purchasing.
As folks experience levels with detector increase more and more worthy data will show up,,finds too.

Even you will be answering questions for folks.

I want all folks to be involved with the info sharing,,and helping each other out.

Now I had rather see folks post their questions they have in public,,that way other folks can maybe learn too from the answers given to the questions.

But for whatever reason if a person feels uncomfortable asking their question in public,,you can always use private message method.
 
This is where the post will be,,for new Impact purchasers both experienced detectorists and new to detecting will be able to read,,,to get them up and running with their units.

As tester and user of Impact detector,,this post I have assembled to help folks who purchase Impact detector to get them up and running.


Folks receiving their Impact detectors read the manual.

Before assembly begins ensure you read assembly instructions in manual.
I have only seen draft of manual,,so still can't comment on it.

Areas to pay attention to when assembling.
Lower shaft coil cable routing.
Entry hole on lower shaft should face towards the back (bottom) if detector is layed on floor.

When you are first assembling use a stable platform to do,,,big table,,floor.
Take your time.

Folks will notice the top half of coil cable will stretch length wise,,,this gives you added clearance for coil cable connection.
Bottom half of coil cable is fixed in length.

When assembling/connecting coil cable,,,both camlocks need to be unlocked and a person will be able to slide upper shaft down into lower shaft to gain clearances needed for assembly.

The connector on the coil cable,,,requires little effort to insure it is lined up correctly,,but new user needs to pay more attention here at first to become familiar.

Upper shaft,,needs to slid in to stem with camlock open,,until the upper rod hits internal stop inside stem.

Rod can be adjusted for length,,but it does have limits.
If going to short,,,user will notice the cable starts binding and pressure is put on the coil,,,causing it to change physical position.

Users of detector,,,experiment a bit for a correct rod length,,,rod does have some increments on it for reference for your proper rod length. Proper posture is important when detecting. Proper rod length for your site when detecting can vary depending on the terrain,,and other things like grass length,,stubble,,etc.
Detector should not have to be force down to the ground,,or forced up to keep coil off the ground,,,,a person will tire out faster with improper rod length set.
With some practice,,this will become second nature.

Coil bolt mounting is easy,,,line up the holes shift coil in lower rod,,,2 washers are used to mount coil,,,be careful not to lose these,,,especially if outside doing assembly/coil changes.

Battery installation is common sense,,,2 things here,,,make sure the cloth like cord in battery compartment is in the groove in the bottom of battery compartment,,and be sure after batteries are installed,,but before door is installed the cloth like cord is not in battery door's way.

The battery door,,,has a very positive fit and lock to it.
Make sure you latch door on both sides,,,you need to physically check for this security here,,,don't base the door being installed properly on your sight,,,actually apply pressure to both sides of door to insure correct installation.
After this process is repeated a few times,,will be second nature.

It is my sincere opinion here for folks who purchase pro pack package,,,if they will use the smallest coil first,,,overall learning curve time is cut with detector.

When you turn on your detector,,,it should be in factory default settings.
To be sure do the following.
After turned on press select button,,then use either up or down button scroll down to FD/save in the settings menu. Next hit the minus button,,you should see the letters Fd in the screen,,,after this hit select button.
This will ensure detector is in factory default settings.
A note here,,detector will time out and go back to detect screen if too much time is allowed,,between the steps noted above. If the detector does time out,,just start over and speed up your process for completing steps above.
Check your backlight setting,,if no backlight is needed turn off.


Users should read manual and become familiar with settings,,especially how to navigate.
User will notice a time out process is built in to detector when making settings changes,,at first this timeout,,,may seem a bit too fast for a user,,,but as they get more familiar and proficient,,the time out process will not be as a possible nuasiance.

New users should focus their first day with detector using 3 tone mode,,this keeps things simple,,,and allows a person to observe some crucial data,,as well as tonal information.

New users should focus on using 14khz exclusively on their first day,,again this keeps things simple and allows for crucial data and tonal information to be heard and observed.

New user should assemble some coins of different denominations,,,nickel,,modern zinc penny,,,older copper penny pre 1982,,dime,,quarter,,Indian head cent if you have one,,, some nails of different sizes, pull tabs,,gold ring,,silver ring if you have one, a few different bottle caps,,a few different aluminum twist bottle tops. and any other things you may have on hand you want to try to detect with this detector. Also user should get bigger piece of iron like a horseshoe.

The goal here is for new user to see how the different items read on the meter.
This how they read is important,,,and this info can and will be seen in the field many times (under ideal conditions).

I recommend the above items be swept at a coil height of around 4-5" of items.
Note,,in case someone gets the bright idea of performing what is called a depth air test,,,seeing how far from coil say a coin of any denomination can be detected by detector. Use of this info,,,is a guide,,and depending on your soil's mineral level content,,,the data gained from air test can be skewed/ reduced (level depends on the level of minerals).

After sweeping these items and noting their readings,,user next needs to learn how to adjust tone breaks and tones while in 3 tone mode.
Doing the above,,,will allow the following,,,changing tone break will force the detector to respond to the tone you set in the range of this tone break.
For example a user can make a modern penny sound different than a pre 1982 copper penny by doing. The goal is to have detector set so targets of interest can be moreso identified solely by tone as you sweep your coil over them.

Exercise
Take a zinc modern penny and get your bottlecaps.
Sweep each individually using 14khz,,note tone (pay close attention),,ensure iron volume is set to 0.
Repeat sweeping each above,,except turn iron volume to level 3 (pay close attention to audio),,hear any differences. You should.

Next take the modern penny and place on clean ground,,,sweep and gradually lift coil while at the same time watch VDI in meter. Note coil height when ID starts reading rather poor(less accurate),,,next lower coil back to around 3" sweeping modern penny,,and purposely start moving coil forwards all the way out to the edge of coil,,,,note when the detector quits providing tone. Next move coil back so penny approachs back of coil's edge.

Now take bottle cap (not twist cap) and repeat above,,note differences...Younshould see some.
These are ways (these differences ) noted to flush out those pesky caps without digging.

Overload tone,,,learn what it sounds like,,,with detector turned on,,,lower the coil over a horseshoe or even an aluminum can. Remember the overload signal can be provided on both ferrous items and nonferrous items (bigger).

The impact with its 3 frequencies capability is different vs many other detectors.
Targets will respond differently depending on the frequency used while using this detector. Users should note higher frequency of 20khz is more responsive on lower conductors like gold rings,,nickels, tabs, foil,,,,where 5khz is more responsive on higher conductors like copper and silver coins and clad dimes, quarters, etc.
14khz is more of a one frequency does all good on this detector,,Jack of all trades frequency,,,it is a solid performer on mid conductive items like shot gun shells, bullets,,zinc pennies,,IH cents,etc. Good frequency for general hunting,,scouting.


Pinpoint button,,when it is pulled toward user,,this is actual pinpoint function,,detector will detect all metals when pulled. User can lay a coin on ground and hold coil over and pull pinpoint switch,,,note a depth reading is present. Users depending on what they prefer,,,refer to users manual to select inches or centimeters. Also note depth meter calibrated for stock sized coil only,,use of other sized coils,,,depth info will be in error.

Eliminating or reducing interference
User should note,,if they are getting audio noise with the coil held in the air (not sweeping over ground),,this is likely emi,,,user should try to eliminate or reduce this interference by doing a frequency shift-- refer to users manual for procedure. Btw it is normal ops to experience some interference when operating your detector in your home,,in a garage with flouresdent lights,,,even in close quarters to homes (external) that are supplied with power--lots of gadgets in them cause interference. Recommend new users to be aware,,cell phones especially if talking on will cause interference.

Ground balance is easy process on this detector,,follow owner manual.
Do balance over clean ground.
I recommend new users to use ground grab GB at first,,not tracking GB.
What about reground balancing after changing frequencies??
It is not always necessary,,,to do,,,but depending on soil minerals an depth of targets,,some small performance advantages may be obtained.

Minerlization meter,,,while ground balancing and bobbing coil,,,note reading in this meter,,,you see no more than 2 bars your ground should be easier to detect,,,3 or more this is where things will be more difficult. I will address both groups here,,,but will give more info for the latter since this is the more difficult.
Special note here-- Mineralization meter is scaled for stock coil,,,using a smaller coil less bars may be seen,,and a bigger than stock coil,,more bars may be witnessed. Good idea to reference your soil using stock coil as far as mineral levels and how performance is affected,,,both positively and negatively.

Default settings on this detector while in 3 tone,,,a user can observe some good performance,,,I encourage folks to get accustomed to using in default settings (except for tone breaks and tone) for a while.

Sweep speed,,,beginners a good pace,,,try to be able to swing right to left,,,actually say to yourself the following numbers 1001,1002,1003,,,if you can actually say all these while sweeping one complete sweep say right to left,,,good pace to start off with to get you started. And again say these numbers when sweeping back left to right,,,good pace to start with.

Users of this detector,,a pinpointer is not a necessity but I highly recommend.
Contact any sponsor here and they can fix you up with one.
Users of this detector should note,,,this detector will find objects shallower and deeper,,and will find worthy targets like coins for example near other nonferrous unworthy targets as well as nails and other ferrous materials. Users should note,,target recovery is because of this,,can be challenging,,,to actually retrieve the worthy find the detector sounded off on. I caution users here,,sometimes when the dirt is disturbed/removed,,Impact detector may stop detecting target.
There will be times even when the detector will not detect your worthy find in the plug of dirt even when it is removed and laying on top of the ground. Iron and other ferrous,,even other nonferrous items can block the detector from actually providing the same tone you heard originally before starting to dig target. So,,busting the plug,,,or using a pinpointer or both may be necessary for successful recovery.

I recommend users of this detector (especially those new to detecting) to go to your local hardware store and buy if you don't already have,,,each of the following,, dozen each of 10 penny nails,,12 penny nails,,16 penny nails,,and a few 20 penny nails. The goal here is get you to understand how this detector sounds while being swept over multiple nails,,and multiple sizes of nails. I encourage users to set up what I call booby traps for the impact detector,,,start out first using one nail and coin,,and vary positions and distance between nail and coin,,a nickel and a modern penny good choices here to use. After you experiment with one nail and coin,,add another nail to equation,,,and experiment. Don't be surprised to see some situations you come up with,,,,for their to be no detection of coin. Experiment with your iron volume setting.
Pay attention when there is detection,,,how does the tone sound,,what does the meter do or say. When you set your booby traps,,without disturbing nails,,,remove the coin and just sweep the nails in their original position and note any sounds made,,replace coin and listen again.
Try to find a clean place no metal to do your booby trap testing.
Now don't be afraid to say place multiple nails over a wider area,,and put a coin in amongst,,,then try and actually sweep around and detect the coin,,,approach from many angles,,,note differences.
When you learn what iron sound like with this detector,,,and learn how a "challenged" target sounds like,,,all down hill from here,,I promise.
Just remember when it comes to the possible scenarios you could be subjected to in the field,,,mind blowing,,,could be like numbers of possibilities of actual power ball number combinations. Advanced use of detector will come with time and exposure to more of these different scenarios. Learning the detector's tendencies around iron and nails very important. Users should note,,coil height can be very restricted here depending on your booby trap you've set up. Also pay attention to overload signal,,,if overload signal starts,,raise coil a bit,,,you may be able to detect your coin by doing. Also I highly recommend folks leave their disc level setting to level 3 here,,,with more experience lower disc may be able to be utilized,,,but to get a good baseline here for learning and understanding level 3 will do nicely. Doing these booby traps using nails and coin,,,user will see usually a lower than ideal vdi noted in meter. This is normal ops,,,and usually if a nonferrous target is really challenged the purity of the tone will be compromised yet still intelligent enough to tell you nonferrous target exist. Remember accurate ID on challenged targets far less likely the majority of time,,,you won't know what you are digging. Could be a gold coin,,tab,,silver coin,,,a lot of things,,,but remember this,,,Impact detector has some grand performance here just by telling user a nonferrous target exist in these challenging circumstances,,,,,many other detectors will NOT do this or do as good at providing intelligent audio alerting you.
Doing your booby traps,,,as they become more and more challenging for Impact note how slow you must sweep,,and how critical coil position is to actually get an audio period telling you the nonferrous coin is present. You should note,,,extremely small coil movement out of ideal position makes the signal a no go for hearing.
Now,,will the Impact detector always sound like it did when user was experiementing with the nails,,will the older iron beneath the ground sound exactly like the Impact did over the nails,,horseshoe your tried earlier?? Yes and no,,older iron and nails that has decayed somewhat,,user likely to hear what we call high tone falses,,,and these can confuse a new user of detector,,especially those new to detecting. If a person will dig some of the iron objects providing these falses,,,they will see a pattern develop and be better able to recognize while in the field detecting. This is directly tied to what I said above about learning what iron sounds like while using this detector.

Target ID
The shallower a target,,odds are it will read more accurate,,as the target deepens,,ID can become more erroneous. In 2 bars or less minerlized soil on meter ID seems to be very good to around 9"(on solo sitting nonferrous target),, real mild soil this distance may be higher here,, remember target size can affect this allowing Impact to ID correctly at less depth or even more depth.
In 3bars or more indicated on minerlization meter,,,Accuracy is provided at shallow depths vs milder soil.
Impact's tendency on deeper targets once a certain depth is reached (depending on levels of soil minerals) will read higher than normal VDI for a specific item(air test reading). And this higher reading,,a higher tone will accompany. An example,,,very possible for a deep nickel to read a high tone,,where as a shallower nickel likely to read mid tone (true vdi) using 3 tone since it is a lower conductor. Also remember a deeper junk target like a tab could also read higher and produce a high tone as well.
Persons using Impact,,,with experience they will based on their soil mineral levels will eventually see a pattern here,,,and can use this to guide them in the field while detecting. User should note default settings likely will cause Impact detector to not be the best it can be with ID at depth,,again with more experience and being able to use higher gain settings,,,this performance will materialize.

Will a person even super experienced dig a nail or piece of iron while using Impact looking for worthy targets??? You bet ya.
But with training and experience with Impact,,,and learning it tendencies the amount of iron likely will decrease over time.
I rate Impact above average for its iron handling abilities and giving clues to users when he coil is over iron or nail vs a nonferrous target.
Some things ferrous wise likely will sound good even to a very experienced user of Impact-- fence staples,,,bent nails especially those bent forming a 90 degree or less angle,,,users digging these,,,are on the right track,,not the wrong track,,I assure.

Notch filter setting
This is the most difficult setting to use/adjust.
It allows a user of detector,,to not hear targets based on the conductivity level (vdi).
Read the manual closely here for procedure,,,a suggestion here,,,if you try and use the notch filter get yourself a pull tab to practice setting up,,,in the event you get confused,,even think you have set this notch up incorrectly and get frustrated,,and can't figure out which way to undo,,,and you want to use your unit,,,but fear your improper settings of notch may cause you to miss some worthy targets,,,have no fear,,,simple,,,PERFORM reset to detector back to factory default settings-- refer to manual if unsure of procedure. This will get rid of any erroneous notch filter settings you may have done. Later when you have more time,,reapproach and try again with your notch filter settings.
User should notice looking at the top of the screen,,there if any notch setting is loaded,,,these marks will be seen at various points,,,,in default setting for example using 3 tone,,,user should notice only 2 marks in the area in the far left of screen. These 2 marks indicate disc setting not notch setting.

I recommend users of Impact detector to set themselves up a test garden,,burying at least the following targets,,,Clad dime,,pull tab,, modern penny,,bury these at different depths,,,like try 6",,7",,8",,9",,,,pick a clean place to do-no metal. Even bury a tab at 6" and a bottle cap.
Let's say you have run Impact detector a few days and understand what it is telling you,,you feel you are ready to step up,,to operate at more advanced levels.
OK
The test garden here will help you.

First higher gain,,,default setting of 85,, what happens when you up the gain??
Impact could depending have more interference audibly depending on emi levels.
Higher gain,,will increase volume of targets especially deeper ones.
Higher gain will allow Imoact detector to provide more accurate ID of deeper targets.
I still recommend users to say in 3 tone here,,,while they are experimenting with higher gain settings.
Very possible for user to run 99 gain settings using 3 tone,,and detector will be stable for operation in many environments.

Users of Impact should not get overly curious and try to make too many settings changes to too many things at once,,,instead use your test garden,,,and sweep your different targets at varying depths,,,adjusting only one setting at a time,,and note the affects of setting change,,,be it at increased or decreased levels.
Try to see where optimum signal is achieved for tone,,and even ID of target.

Using other frequencies
Very easy to select and change.
Important here for users to understand some targets due to their size and conductivity some freqs here will strike deeper targets vs other frequencies.

A brief description of what each frequency can do for you,,,based on your detecting sites.

5khz
This frequency being the lowest,,Users will notice some depth advantage on higher conductive things like silver coins,,copper, etc
Swing speed will be less forgiving while using in the ideal sense,,,using this frequency, Impact detector will not separate or unmask around iron and or nails as good as the other 2 frequencies.
Better use of this frequency in general is more open areas,,where less iron and nails are hiding.


20khz
This frequency is the highest,,users will note some depth advantage on the lowest and smallest of nonferrous objects.
Use of this frequency allows for Impqct to operate at max potential for separating and unmasking nonferrous objects in around nails and iron.

14khz,,as I have already stated,,a good general frequency,,,should also say,,even using Impact in 14khz,,it's separation and unmasking abilities,,even here are very good,,,better than a lot of other detectors,,,users will note,,when hunting heavy iron when comparing 14khz operation vs 20khz operation,,detector as far as audio,,the smoothness while sweeping over old buried rusty nails and iron is better using 20khz.

So what can changing frequencies do for you while using impact??
Impact having the ability here to give user other primary frequency groups to operate,,,,gives a user a better chance to find a useable frequency to use to detect in high emi areas. So changing freqs,,as well as doing frequency shifts give users more options to mitigate for interference.

Next,,here is some thing to point out,,and this will hopefully keep new users from some confusion.
A user can save a program mode with settings changes they like,,even pick the frequency.
At detector turn on,,this is the frequency that will be in use.
If a user changes modes,,,frequency in use at time of mode change will carry over to new mode.
I encourage users to always be mindful of which frequency is being employed when detecting,,,can cause some loss of performance depending on your site if not mangaged properly.

Will targets ID the same when Changing frequencies when swept??
Yes and no.
It will depend on if user has feature on Impact detector called Normalization turned on or not. Factory default setting is ON,,meaning ideally you sweep a coin,,,it will read the same vdi,,using all frequencies.
Remember I used the word ideally here,,,targets setting solo in the ground,,and at reasonable detection depths this will happen moreso.

Turning Normalization Off,,,refer to manual for procedure.
What is the advantage of having Normalization turned off?

It will force Impact detector to provide different VDi readings on the same target,,when swept with each individual frequency.
I encourage new users to take the items I mentioned earlier here and sweep each one using the different frequencies and note the differences.

This area here using Normalization off will be the area where the most confusion takes place for new users,,especially folks new to detecting.
Why??
Because with normalization When it is turned off,,,detector will report different vdi over same target when changing frequencies.
Remember your tone break settings???
These tone break settings will as far as audio produced,,,,will be altered,,,since for the most part sweeping the same target comparing 5khz and 20khz,,differences of approximately 20 points will be witnessed.
I encourage new users to get pen and paper and record their readings while sweeping various targets,,,when changing frequencies.
This info will be very beneficial later when you are deciding how to set up your tone breaks when using modes 3tone and 4tone.
So folks need to remember when changing frequencies and using 3 tone and 4 tone modes,,,new tone break settings will need to be accomplished if user desires similarly sounding tones while sweeping the same target using other frequencies.
SPECIAL Note here--- notch filter settings,,these too will be affected if a user changes frequencies with Normaization turned OFF,,so new notch filter settings will likely be needed.

So now users should realize using normalization Off will change readings vdi wise on how the detector reports,,,can this CHANGE in reporting be used to be benefit a user???
Yes
This is one way a user can use Impact to actually ID junk targets like can slaw,,aluminum twist caps,etc.
A good general rule of thumb,,,if a target reads while using 14 or 20khz say upwards of 79 in the meter,,and user changes to 5khz,,and the target reports below 60,,,this specific target is likely a junk target. Now this is only a guide,,I encourage users to experiment while sweeping their test gardens and even things on topmofmthe ground,,as well as digging targets in the field.
Remember gold jewelry can read anything in the mid to lower conductive range,,,there are no real shortcuts to elimate other lower and mid conductive targets to just detect gold,,,only discrimation here is YOUR eyes.
Granted most gold likely won't be giving higher meter readings when swept unless deeper.

So what about the DI99 mode??
What is it,,and how does to work,,,and where can it be used.
This mode basically allows user to use Impact along with other settings even frequency changes,,but DOESN'T allow for tone break or tones settings.
Why??
Because the mode reports all nonferrous on a sliding scale,,lower tone for lower conductor ps and higher for higher conductors,,your tones are preset so to speak.
This mode is great for hunting iron laden places looking for nonferrous targets. using proper techniques.
Using this mode,,Impact will report very fast,,and some of this fast reporting is driven by coil sweep speed.
Hunting using this mode where there is an abundance of modern trash,where the user is trying to select only the higher conductive targets like coins to dig,,a keen ear is needed,,because Impact will sometimes report on the higher conductive targets nestled in amongst other lower conductive modern trash with a very short tone,,,using modes like 3 tone and 4 tone (with proper tone breaks set) here generally easier because they will put different buried things into groups for reporting tone,,,easier for new user to be alerted to higher conductor using. Remember turning Normalization off applies to this mode as well,,will cause same target to report differently vdi wise as well as tonally,,so a user since they don't have means to adjust tone break,,,no way to make a target sound similar or the same vs using 3 tone mode.

Back to coil sweeping
You have already read my recommendation for a coil sweep speed.
Folks should let what the detector is telling them as far as target density and amount/quantities of iron and nails drive their sweep speed.
It is not imperative for a complete side to side movement coil sweep wise to be done,,in the trashiest of areas,,,coil sweep span can be done with much shorter sweeps,,,with experience,,,you may find yourself only having a 6"-1 ft span at times when trying to find the goodies depending on the site.
More ground covered using Impact certainly not always the best recipe for success.
Reducing swing speed and coil span can decrease chance of information overload as your detector reports to you audio to you.
You must walk before you can run,,,you keep this in the back of your head when using this detector,,,in the long run,,your learning overall will be better,,and your future success better.
Be leery of hopping on the bandwagon with other users settings,,,stay true to form on your learning this detector.
As your experience grows with using,,you then can broaden your horizons on settings changes and trying different techniques while trying to make some incredible finds.

I can say based on first hand experience,,,some users at first may be dissapointed with their Impact's performance. Or feel the detector is too complicated for them to operate.
If you will give this detector a chance,,,and spend some time with it,,,it WILL perform.
To give example,,,even with as much as I have run Impact,,,light bulb started burning real bright around the 100 hour mark usage wise.
But I wasn't provided all the information I am providing for folks here.

The Impact detector can be made to perform more like a mediocre performing Vlf detector,,and actually be simpler to operate,,,,but this IMO shouldn't be any users future goal of using Impact detector.

New users,especially those new to detecting,,I highly encourage all at first anyway,,every good suspect target,,before you dig,,,if conditions will allow,,,continue to sweep targets while walking all the way around target,,,noting any differences in tone,,and meter readings/behavior.
This is very important,,,and with time,,will prove very useful in your overall ability to select targets in the future as far as being worthy or not,,,or nonferrous or not.

Here are the things,,,that with more experience using the detector,,,you will get better at doing.
Being able to recognize iron or nail for what it is.
Knowing whether or not the meter is reporting to you (how accurate) is it,,,how believable.
To even locate a target,,deeper or a heavily masked worthy target.
To be able to identify junk targets and thus not dig.

More intense learning will occur using Impact if a user will even rehunt their sites behind themselves,,,this is exactly what I did.
An area with more trash and nails,,,you keep hunting these,,,and you'll start to notice things,,,by sneaking out finds,,you will be incrementally subjected to having to find tougher targets and in doing so,,the grand performance of Impact will hit you. And will put a smile on your face.

I do encourage folks to hunt with their buds,,,compare target info,,even hunting with a very experienced detectorists using same or different model detector-good thing.
Now,,don't be dissapointed if one of your buds who are using a detector they are more experienced with to out do you.
You just keep things in perspective here,,,with time,,,you may just be giving your more experienced bud a few lessons in the future.

Users of Impact should eventually develop a regiment of things they watch and listen for to find,,or Identify a target.
This list here at first will be shorter,,,but as you grow with detector,,your list will grow with things you think about (check off) when deciding to dig or not.
You even after several hours of using this detector,,,your regiment of thinking when looking at a suspect target,,,will sometimes due to gut instinct be violated for one reason or another,,,and by doing you may surface a nice find or even a find of a lifetime.

There are no absolutes when it comes detecting,,,except for one.
You will never detect a worthy target unless you use your detector,,,this one I'm sure of.

Salt water beach hunters
Remember Impact not waterproof,,just the coil.
I have never hunted one iota on a salt water beach,,so can't give any detailed info.
My suggestion here,,start with default settings and work from here,,and just maybe some other users will also talk about what they are witnessing,,and you may get a tip or 2.

This is it folks.
The above information,,,if studied and applied will get you on your way using the Impact detector.
A lot to take in,,,but it will help you I think.

I didn't mention all metal use of this detector,,,and this was on purpose.
All metal use is more for more advanced users,,,personally I don't use much,,I find using the modes of 2 tone, 3 tone, 4 tone and Di99 modes to suffice for most of my hunting needs. They work too good for me to forage around using all metal modes.

There is talk of using these elsewhere on other detecting forums if interested,,,but I strongly recommend you get a handle first on all the above before choosing.

You will have dissapointents over time using this detector,,,you will have success too.

Folks should refer back here periodically and reread this,,,as well as their operators manual,,,,and take note of other users' data as well.

I have likely not unlocked all the things this detector can do.
I don't think anyone else has yet either.
But with time,,,all the users combined if we could pour all they know into one person's skull,,just maybe we would someday have a person who knows all there is to know about this great detector.

Remember this detector is internet updatable,,,very possible for the manufacturer to release update in the future.
Users need to say abreast of any update information.

Good luck and happy detecting.

I notice someone having a problem while relic hunting in fields with can slaw.

What can the Nokta Impact do for the situation???

It is true higher conductive targets can be ID vs junk lower conductive targets using the non normalized settings,,,comparing 5khz readings and 20khz readings. Or even comparing 14khz readings and 5khz readings.

So what about things like bullets,buttons, bigger brass items--mid conductors??

Here is what a user likely to see,,,mid conductors will strike in the 46-56 range primarily using 5khz,,,where can slaw will hit in the 30s to lower 40s.

So a person can set themselves up a threshold for acceptable digging based on how low a target reports in 5khz.

I have actually dug some of these mid conductors reading in the range above.
Dismissing all targets in the 30s range will get rid of a whole lot of smaller can slaw.
Now this is not an absolute fail safe way not to dig can slaw,,,but I'll bet the farm (all 125 acres) it sure is better than nothing.

For can slaw to read 45 it would have to be folded or sorta big,,so if I got a 45 in the window in a CW relic field,,,I can still pinpoint,,if it seems smaller,,
I would dig.

Now the smaller cuff buttons,,,one would likely dig the can slaw going after those. With any Vlf detector really.

Here's a subject some folks may be interested in.

How about the tiny can slaw,,22 caliber hull,,,other smaller lowest conductors.

How does Impact do on these???

Now remember I Have said it is possible for Impact to up average even a lower conductor and give high tone.

So what happens to these smaller lowest conductors when sweeping using 5khz??
DI99 mode gain at 99, disc level 3,,no notch applied.

Will some of them give high tone??
Yes

But here's the kicker,,,a user will notice the tone real short,,and flashy sounding (not ideal tone at all) ,,will likely not likely repeat between sweeps,,coil position more extreme.

Now what I find is good to do,,is have iron volume on.
If I hear no iron volume,,,that is telling me likely morse a more solo sitting nonferrous,,,not masked,,,,,if I heard iron vol trying to roll in,,I might dig,,,,but no iron volume,,,write the target off as a junk lower conductive target.

Now,,if I dug one of these,,,and it turned out to be a 22 casing for example,,and I heard some of these short high flashers in this area,,,I would surmise more of those little pesky hulls.

You have tools on board with detector,,,to be able to make more educated guesses,,,not digging the junk.

Also,,,these little hulls,,,in 20 kHz,,they likely to give a decent tone,,,so again this points to lower conductor since the target doesn't want to report very well at all using 5khz.
 
Low conductors are what i hunt for, that's where our small hammered live.
The problem we have in the UK is that we have hundreds of differing coins of varing conductivity, if it sounds small, clean and round we have to dig it.
They say here that screens are for park hunters and audio is king, but the screen on some detectors can give additional info, the aka, gm5, rutus 71 etc as there not just number based.
Maybe Nokta missed a trick here.
 
What an awesome summarization by Tnsharpshooter! This is good stuff even for users of other detectors. Thank you!
 
Finally some good info a person can use.

I notice there is three different frequency's which pretty much cover what most of the market offers. I would like to know a little about the higher frequency's. Im not ready to turn loose of my proven F75 or AT Pro. But these two detectors dont have the higher frequency one would use say for nugget hunting. I see the Impact is sensitive enough to find small items. Have you had a chance to test small gold with the Impact? Any machine that can find small items like that is worth looking into. I am confused as to what kind of detector the Impact is? What would you call it TNSharpshooter? Relic, coin, nugget?
