Deep silver vs. large iron discrimination on a Silver U-max.

[Darkflight]

Working a park that I know has some deep silver. I know because I've found some. Also I found the sites trash dump so I know how deep the "old" ground is. I should be in the 6-8" zone for these coins.Other than a ground rodent pushing a deep coin into his debris pile-Wich I have had happen twice-I'm not doing very well pulling the goodies from the trash.

Likely going about it wrong so I'll ask advice.

I don't mind digging up an old splitter or something cool. But I'm after the coins & want to improve my odds.Lots of large iron in the prime target area,

I can run the stock coil same with the disc set above zinc/max sensitivity or very near. Decent soil in this area. Again-trying for the deeper targets.Works well till I hit some iron & then I have a hard time telling good from bad.At this point if I can't tell I dig.

But am I using to much "gain" or sensitivity for these conditions?. For the last 2 trips I've been zero coins & a large bundle of trash.

I have a 5.5" coil on the way for the heavy trash. I assume that will help some for masked targets but depth?.

My 10 x 12 coil really works best for open fields-few targets. I've tried using it to gain a depth advantage in the park. It's more sensetive & I have to run it at 7 to get rid of constant falses. Also,multiple targets are easily covered leading to mass confusion.I guess bigger is not always better eh?.

So-what is your favorite "nothing but net" setting/coil combination on the Silver U-max???

Personally I love the silver umax, but given the choice I'm going to use a manual ground balance machine. With the vaquero + 5" coil I can go over the same signal that was good or questionable and completely ignore it. The silver has the stock 8" coil on and has a fixed ground balance. I think the 5" coil helps more than anything.

Size the target in all metal mode.

The 5" coil on the silver is going to help, but you should prob send it to Tesoro for the 5" coil setup. I never take mine off so I think sending it in once is all you'll need to worry about.

You'll lose a little depth, but if you're hunting in iron odds are you'll do better.

Just listening to the silver umax ( even when I'm not the one using it) I can often tell my co-hunter, that sounds like Iron.

I remember when I started I thought medical detecting was more of an exact science.
It isn't and often I have to make educated guesses. Read about or google "how a metal detector works." and how frequency and conductivity work with detectors.

I actually like iron, because I know there's been activity in the area.


I'd post links, but I'm on an iPod touch right now.

I hunt in similar situation with same setup. I have had great success using the 10x12 on the Silver uMax with DISC maxxed out and the SENS pretty close to maxxed out. From my experience you just can't DISC out the silver on a Silver uMax. If you happen to find a hot spot, you can turn down DISC and/or switch to a smaller coil and look for coppers and such.

I never tried that method you described . I think the problem I'm having is truly large/old iron-with lots of rusty halo-in the ground.

I went all day, 3 parks today & never had a false iron. I had a few I played with the disc to try & determine the target & as long as it was solid I dug. The signal blanking out when you slightly lift is another good tip.

Funny thing is-the ones that really get me diggin-square nails ussually-don't register a blip once I've unearthed them. More evidence on how rust never sleeps...

Thanks!

Sounds like you're gonna just have to get all that trash outa there first. I've had some luck in tab-infested areas with setting the disc where tabs just crackle-but I think you're gonna have to clean house.

I hunt with the disc. just above foil and then go to above tab to check. The silver seems to find alum. and other metals no matter what the setting if its balled up. I use the 12x10 and max out both and find more coins than trash but the trash still comes. The higher the disc the less falsing on full gain. Not the best desc. out there but a real coin killer. I use the 4" coil alot and have learned how to fish through the trash with the 12x10. Cant block the silver or pennies for that matter. Coin KILLER and rings too.

something that may help you is sizing. I dont know if the silver has an all metal mode? if it does you should be able to get an idea of a targets size. a coin deep is going to be a smaller sized sound, try sweeping from different angles to help.
