So sorry to hear about your loss shooter. Its never easy losing a family member. My father passed 2 months ago and I miss him dearly.
I read this post thread multiple times before I decided to purchase. Thank you very much for all your hard work in testing the unit. It gave me confidence in purchasing the impact. I have some extremely trashy parks that I want to test it out in where I know some silver coins are hiding. I also hope it does well on gold jewelry. What settings would you recommend for a situation like this?
For a trashy site with ferrous mixed in,,,,you have a few options.
20khz will get you max separation,,,disc at 2 or 3 will do.
I would stay out of deep mode for a while,,it's not what you want in trashy sites anyway.
You will have to pick a mode.
For silver 3 tone will work,,and with proper tone breaks set,,you can hunt by tone moreso.
Di99 will work,,only problem is in target rich nonferrous environments you'll have to stop and study both tone and screen morseso.
A word to the wise,,,this could be considered advanced use info,,,but hey a person can jump right in with using it, and maybe pull some nice finds......one of the biggest advantages I fell Impact brings,,,especially uaing smallest coil,,,the way the iron vol works(I like mine at level 1),,,a person can tell moreso if the detector's ID is less or more reliable,,,meaning in an old site you may get a mid level reading target,,and can tell by how critical coil movement and or position is to acquire signal,,,and listen to the iron tone. On these kinds of targets,,,beware of seeking ideal meter reading targets,,,could be a good ole silver being heavily masked by iron or nails.
Being able to use I pact and discern if a target is solo sitting (no ferrous or likely no other nonferrous around),,, you detect this in 20 or 14khz and flip to 5khz,,,if the meter goes to low 40s or lower,,,you can almost bet the farm not copper or silver,,,,could be an IH coin though.
Also,,flipping to 5khz and if it seems signal is more comprosmied or dissapears altogether,,,this can be a symptom of a more challenged target.
You can take Impact in behind Minelabs especially when iron is present and hunt behind them.
Gold rings likely won't read if solo sitting in the 20s or 30s Vdi wise,,,small gold could though.
A person using Impact has to watch coil management,,,when it comes to advancement. An extremely small spot is all that is available sometimes on heavily challenged targets. And yes,,direction of approach can be altered too and a person may hit a good find.
Don't let Impact's recovery speed go to your head for coil advancement in trashy sites.
Impact will talk to you,,,,but you do have to give it time,,,and you have to be able to comprehend.
Remember the 1916 merc dime I posted in this thread,,,there were 2 other finds found nearby,,,all 3 of these had been swept over with countless detectors.
But only one was a coin,,,one of the others was lead,,I forget what the other was,,but being where this area set up with the church,,a person if they could get a signal on these,,,they read mid to high conductor,,and a person has to dig.
I listed some exercises in this thread,,,I encourage you and others to experiment by doing them.
An Impact user needs to understand what a nail sounds like,,,different size nails.
They won't necessarily come through with tone per SE,,,depending on size,,they will come thru as iron tone if you don't have set to 0 (off).
Iron vol on Impact at levels 1 or 2 is your best friend,,especially when cherry picking trying to place odds in your favor when deciding to dig,,,especially in a hard hunted site,,hunted by yourself and or others.
Be very conscious of where you have hunted before,,and with which detector and coil sizes,,,,capitalize on these other detectors weaknesses.
It won't be long you will start to see a pattern especially if rehunting sites that were producing some good finds.
Don't let your first 2 or 3 hours running Impact disgust you.
It will happen to some,,,I guarantee it,,,big mistake though.
Keep running it,,and it'll show its stuff in due time.
Milder ground,,and cleaner,,deep mode with higher gain 95 plus,,will get deeper.
Don't let depth always be your driver when detecting either,,,if you do,,another big mistake.
Stock coil,,same rules apply as far as higher freq aids separation and sacrifices some depth.
14khz is a good all arounder,,,but in iron,,watch coil sweep speed moreso.
Iron falses/wrap,,,you will see 90s a lot of times,,and the tone will be off/not as ideal sounding like nonferrous,,and likely not consistent.
Toggling after you get iron wrap discovered using 14 or 20khz,,,you switch to 5khz,,,good chance you'll see the same reading or very close if iron.
With use,,a user of Impact will develop their own rules by which to guide themselves,,,using whatever tools Impact gives them.
It won't be long till folks will be sharing their experiences,,and folks can learn from one another,,,even me.
That's right,,even me.
I make no claims to know everything about Impact,,,just too many variables out there,,,some good trade secrets no doubt will be discovered or tendencies this detector possesses to give folks better ideas to develop better skills at using.
I am looking forward to reading more about the Impact.
