AT Pro Settings in heavy iron area

[JeremiahEdward]

As the title states, I'm hunting a friends yard (house was built in 1901). I just upgraded from an ACE 250 to an AT Pro. What settings do you guys use to combat iron masking? His yard is FULL of layer after layer of nails. I have been listening for the high chirps to ring through, and when they do it's impossible to pinpoint where they are at due to the pinpointer (on the AT Pro AND the Garrett Carrot) hitting all of the nails. I don't want to dig up his yard as he was kind enough to let me detect there.

I have a similar issue at a local park. I dig up a plug and the soil 4-5 inches down is orange/brown (rust). I ground balance, but I still get a lot of broken signals and junk chatter.

Thanks for the help guy and gals!

Do you have the smaller 5x8 coil or the NEL Snake by any chance? That's what you need in trashy areas, the stock coil is too big, it will go nuts. The small one is both easier to pinpoint with and will seperate the targets much better.

However here are my settings (not that I'm a pro, but everything here is ridden with trash):

Custom mode that is basically Pro zero mode with everything notched in. If you are just after coins I say set the discrimination so that it only picks up targets with a conductivity of 60 or higher, that will make hunting very easy but you are going to miss gold rings. As you say it's a back yard chances for gold rings are slim so you might like pretty high discrimination. I leave the iron discrimination set to 32-34, that seems to work really well for me at least. So this way I basically only ignore iron and try to dig everything that gives a repeatable signal. If the iron grunt sound lets it seem like a trash target I switch the direction of my swing 90 degrees and try if the different angle changes the sound. That's how I differentiate between close by iron targets and trash signals, seems to work quite well for me. Swing slow, it will give the detector more time to seperate targets.

Anyway, trashy areas with the stock coil are a nightmare, the small coil changes everything.

Curious as to why you don't set iron disrim to 40 max?

I agree strongly with small coil. The Snake seems to do the job and still get good depth.

Thanks

Where I don't hunt I don't want to ignore gold and with the iron discrimination maxed it doesn't only get right to where gold starts but also ignore a lot more targets if they lie close to iron targets. You can test that quite easily by lying a coin or ring between two iron nails and going over it with the coil at different iron discrim settings, you will most likely pick it up with the small coil and 32-34 but it might not even sound off with 40.

Thanks...I will try that out today if the rain lets up. I always maxed out iron at this site before. Will be interesting if I find more targets.

Set iron disc to about 32-35 and run iron audio on. All other disc wide open. You will here small iron as a low grunt mid conductors and larger iron as a mid tone and higher conductors as a high tone.

In super heavy iron sites (notice I didn't say heavy trash sites, trash isn't just iron as we all know after the 20th bottle cap that sounds so good!) I run in Pro Zero mode with NO iron discrimination. I have done many tests where if a coin or nice target is close to a non-ferrous target will mask out the good target if your discrimination is set to high With the AT Pro where you set discrimination at sets the midtone with iron adio on, thats a key thing to remember. lets say your discrimination is at 30 and you turn iron audio on, any target with a VDI of 30 or above will now be a mid tone. Try it yourself with 2 square nails and an Indian head in the middle about 1 inch from the nails. Now try discrimination at 35 and turn Iron Audio on and hit it again you'll start to hear the coin come through.
So for me, it's sensitivity at max, Zero discrimination, NEL SharpShooter coil, Grey Ghost Black Widows run full volume.

No iron discrimination?....at all? The places I hunt would blow my ears off the whole time. It would be...one....long....beeeeeep......

you want to find the good stuff cut the discrim off and listen to everything if you want a quite life follow the advice above but know this YOU ARE LEAVING GOOD TARGETS BEHIND when you start notching and running discrim. Its a double edged sword ones noisy but the other cuts masked targets out too. I hunt with no discrim and have seen plenty of masked targets if I had have been using disc and notch they woiuld still be in the ground. I have dug civil war buttons that rang in the 40s on the pro Take a coin and put it with nails and watch the numbers drop. Of course there are different schools of thought on this so you will have to decide for yourself.

If you're digging CW items, you can't be in as much iron as what I'm talking about. Demo sites where there might be three or four hits under my NEL Snake at one time. Places where it literally would make a constant noise if you had zero disc. Places where there is a "sheet" of foil, aluminum, iron and on occasion, sheets of tin. I understand bumping it down, but off would seem to depend on the site.
TrasureSeeker....I'm betting that we are talking about the same type of site. I do the same as you.....mine goes to about 32-34. Still screaches most of the time but better than the entire time.

 

[lockster99]

You don't have to notch out everything.... Just bump up the iron. These came from an extremely trashy area and all were mixed in with iron nails.

 

[rick67]

IMO. Wide open is the way go into it. No discrimination.
Unless your coin shooting. It's the best way to learn.

This is the type of iron I hunt and this is thin compared to some of my sites.

I like your video. Very informative, but still not the quantity of trash I'm talking about. With some discrimination.....I'm still listening to about as much as what you are in your video and your running wide open. But I will say this, it has made me realize that when I leave and go to the next site, often times I don't bump the discrimination back down again...when I probably should. I'm surprised how fast the deus distinguishes each hit. That's super nice.

 

[Calabash Digger]

thats not even the fastest setting either. I hunt thicker stuff than that when I can find it . actually I love to hunt it because alot wont or cant hunt it and I most of the time I pull something good from it. Ive got a video that compares the deus and the pro on recovery speed check it out its very informative.
