Fisher F75SE Boosted Depth

[LOSTmyMARBLES]

I'm looking at upgrading from my F4 and a friend told me about the F75se. Thanks for the post, I'm putting it at the top of my list of options. I was looking at spending around $1000 anyway and it falls right in that slot.

 

[DIRT DOBBER]

Ok my brother just called me and told me to read this post, Thank you for being bored and starting this Dirt Dobber. I have been running my F75SE for a little over 3 weeks now and have been able to get out almost every day from a couple hours to 6-7 hours for the most part.

A question I have is this, I am using the F75SE everything is typically set to factory (Sensitivity 60, GB +3 in DE Mode with 3 tones) when I hunt except I will play with the disc some. I seem to constantly come across 4-6 or more targets on a hunt that will give me a high tone when I hit it and will show on the LCD high 60’S to low 70’s then I will walk around all 4 sides and my numbers can jump as high as 94-95 and back down to the 70’s. This target can also show a depth of 9-12 inches as well.

Would you dig this target ?

I have dug a few of these but only to never find the target. Now maybe I don’t dig deep enough cause it seems to me when I have pin pointed and if the target is reading 8”s I typically find it a couple inches short of that.

Another thing I can find when hunting is a target that will come in right away low 90’s and will pretty much stay 92-95, when I move off the target spot the numbers will drop some but never more than 10 digits or so. I always seem to have a real hard time pin pointing these high targets down and if I move a foot away and come back it will still come in all the same but I just can’t never hit that sweet spot and pin pointing will show it 10+ inches down.

I have played with power boost and all the setting to try and get a stronger single but 99% it really does not change it. Also the chatter or emi can be low to none on some of the areas I am in when targets like these come across but the grounds are target rich from clad to iron. One area we pulled a Barber dime 6-7”s down, well my brother did anyway.

Just wanted to know what others thought

Thanks for the nice words. To your question about whether I'd dig that taget or not. If I were you I would. Over and over until you know what it is you are hearing vs. finding in the ground. Anything that is consistently high and relatively stable like the targets you describe have a good chance of being a nice relic. That being said high 90's are as likely to be iron as 1-7. I suggest digging all repeatables high tones (4 ways) and all signals that jump into the 30+ numbers without bouncing down below 12 or so. until you start to see patterns in the junk and then you can start skipping those. Remember some junk targets/signals are good relics.

Pinpointing in a target rich environment can be tricky at best. In the senario you describe with lots of iron, etc. I don't pinpoint. Just rotate around the target as you sweep and find the center and dig. If you want to pinpoint, find the center of the target as described above and move 1-2" off center and hit the pinpoint trigger to verify the target position. (My guess is that is what you are doing wrong with the pinpoint mode. You want to be just off the target when you PP or you'll pick up other items in the ground and throw your PP off.)

Sometimes when you get those high tones and numbers it is falsing off the end of a long nail or long iron farm junk and the target will be in your sidewall. If you don't find it in the hole, reswing the detector and you should notice the target has moved to the side.

Hope that helps. Keep plugging away, all the things you describe will cease to be problems for you with a little time.

DIRT DOBBER, just curious on how the F75se does in trashy areas? My F4 loves cans, and find myself giving up sometimes in trashy places.

If I may answer this one........
Last week I went to an old house site near a battle in VA. The house was built in 1865 and was demolished early last week to make way for some new apartments. I got permission to the construction site and started swinging. Most of the other relic hunters that showed up were searching in the front yard near the old road. I switched to the small 5" white coil and went for the spot where the house used to stand. There was trash, bricks, wood, cans, nails, and debris everywhere. Poking around through all the trash, I was able to find a few buttons, bullets and coins at amazing depth with the small coil (in boost mode), not to mention my first Standing Liberty. I also found a rusty iron gun hammer to an old musket which was about a foot deep.

So to answer your question, this machine is amazing in trashy areas. If you have a fairly confined area, dont be afraid to use the smaller coil, you will still get superior depth.

Couldn't have said it better myself. It excels.

Thanks. I think I'm sold

E-trac - F75se

Well guy's i took the E-trac out today at a old school yard,pulled 5.17 in clad no silver,tomorrow im going back running my F75se in boost,the ? is,i like that hot little 5dd,i like the 11dd or should i run the 15dd lol with a swingy thingy,i guess i would probally do the best with the 11dd,what's your opinion,i know there is silver thier,deeper than 6 inches,Earl

 

[Captain Silver]

I love older than 1960 schoolyard hunting! I've never run the 15", but would figure it'd be best only if it was a big open field with few targets. Between the 5" or the 11", I would use the 11", and go over the areas you hit with the E-Trac first, then expand your search. The 5" is good in extreme trash situations, but I find it too small to cover a lot of ground with, though the depth is almost as good as the 11". Bring both with you, and start with the 11" is my suggestion...Good luck, and let us know how you do.

Captin silver

Thanks Bruce,the 15dd is heavy,so heavy that without a swingy thingy,after 15 minutes your done,i think it is best for relic hunting,i have been using the 5dd,in school yard's there is heavy trash,i also like the fact that there is no pin pointing with it,just cut the plug under the 5 inch coil,and your right it does almost the same on depth as the 11dd,i didn.t make it back to that school yard sunday,because i had to shuck oyster's for the super bowl,but i will return,i am gonna hit the nieborhood up for two hrs today 55 degree's the last time i hunted the sidewalk strips up i got lucky,see pick,thanks for the advice,Earl Found with the 5inch dd id was a solid 35 2.6 grams

Hey all,

Ive only just joined here, already asking questions..
I live in Australia and also use the F75 SE. (black)

Its been great but contrary to the comments above I have found it very hard going in trashy areas, even with the 5" coil.

For example a recent hunt was at an old house which burnt down, leaving its nails everywhere.
I literally did not find a thing, anything decent seemed to be well and truly masked by iron.

I also struggle to distinguish between ring pulls and good targets.
Ring pulls come up between 40-50, but so do many good targets...thoughts?

What sort of settings are you guys running?

Any advice appreciated!

Cheers
Ash

Spots where homes have burnt, etc. and are covered in a layer of nails are one of the worst problems in MDing. Many spots like that are undetectable with any equipment until many nails have been removed. They are project areas not areas that you can slide all the goodies out in one trip. I have spots like that I've been working for months. Ring pulls are also a problem as are any coin shaped junk item. MDs don't have AI. You will find the differences between coins and ring pulls are subtle and nuanced and take some skill to differentiate. Keep at it. At least you are at the point where you're problems are relatively advanced issues. Cheers.

You might want to try the 5dd on the burnt out home sites,i wish i had had my f75se and the 5dd yesturday as i had my e-trac with the stock 11dd,drove me nut's,finally i gave up,i ordered the sef 6x8 for the trash,i have not yet learned that machine,but i do like it ,captin silver,doesn't the falsing issues drive you a little nuts a boost 99,let's here about your technique,running in this mode at 99,as since you have been running wide open in boost,we might pick up on a few thing's

 

[Captain Silver]

If there is a falsing issue, I must not notice it...When I was working my way up to full power as I learned the machine, I noticed some falsing in the 85-90 sensitivity area, but once I got to 99 and kept running it there, I don't hear it anymore. My current settings for land hunting, be it trashy parks, schoolyards, open fields, woods...anywhere besides a cellar hole/homestead site, are as follows...G.B.+3. Boost Process. Discriminate Mode, disc set at zero, sensitivity set at 99. 3 tone setting. Any questionable target, I'll switch to All Metal mode to help with a target i.d. but as time goes on, I find I don't need to do that much anymore...I see no difference in depth running in Disc vs All Metal, but I get a better target i.d. in Disc....At a cellar hole, I use the same settings, but run in All Metal mode mostly, because of buttons and other relics. I keep the 11" coil mounted at all times now, I got good at separating the keepers from the trash because of the constant 'bottlecap park' and 'pulltab school' hunting, several hundred hours worth. I still learn something new each time out, but it's all advanced training now, I graduated the basic course and am working on the MD doctorate now...

I use it occassionally at some sites but I find the 11 is like a razor blade in the ground and I can usually manage fine without swapping out. I find the factory DD on the Minelab isn't nearly as tight as the F75's. YMMV.

I run at 90 sens/disc4/bp/gb+2/3 and get no falsing to speak of either.

Anyone use the Cache with the 5 in DD coil.
I run in BP mode most of the time and know the Cache mode
was made for big targets but have read of some doing
well with this setup.

I plan on giving it a go this season.

I haven't. It seems sort of counter-intuitive but I've seen many of those work out great. Give it a shot and let us know how it goes.

I tried a air test .
From BP to Cache mode it added a good almost 2 inches
on a dime.

No, it is the deepest mode but the processor is very slow. Not sure how it'd work in the real world and I find BP at the limit of what I want to dig 50+ holes at. Let us know if you try it out how it IDs deep.
