XL-PRO Bottle caps?

[HaroldILL.]

I was wondering is there a trick to tell steel bottle caps form coins? I notice the XL-PRO I just got seems to like them a lot. Also if you crank up the signal balance a little at a time for more depth do you have to re ground balance every time? Thanks.

First is the Sig Bal - this should be set as high as you can when you first ground balance. That is, set the ground balance, adjust the sig bal up and re-ground balance. Repeat until you can't ground balance, then lower sig bal until you can ground balance. Or do like I do and just start with sig bal at maximum and keep lowering it until you get a good ground balance.
So, to answer your question - yes. Every time you adjust sig bal, you have to re ground balance.

Place a nickel on the ground, adjust disc until you can just pick it up. Steel bottle caps should now have a sharper, more broken up audio than coins, making it easier to tell the difference. Though they will still fool you.

I thought to maximize depth you should just disc. out nails and accept hot rocks?

Monte has some tips on his AHRPS website, on steel rusty bottlecaps I use his Quick-Out technique. To do this, pinpoint the suspect BC and make a fast sweep over it and it should break-up the signal quite nicely.

The less you disc, the greater your depth. However, the less you disc, the more you'll dig. Only you can decide how much you want to dig, or how many "bottle caps" are actually coins or rings.

I also heard from a bunch of users the analog I.D. can split hairs and tell silver from clad. I notice this in a air test to about 6'' clads dimes hit between the di and silver dimes hit between the me.I know this isn't 100% of the time,But that is pretty cool though!

It is a pretty awesome detector. I'm going out of town this week and am sitting here contemplating which detector(s) to take, and which to leave behind. I'm planning on hitting a Boy Scout Camp, so the TDI is pretty much a given, and the DFX rarely gets left behind, but I'm sure considering the XL Pro for this trip...

There is a common trick I use on other detectors. Try walking the coil off the target to see how it reacts compared to a good target. I would bet the bottle cap will jump all over and good targets remain pretty steady.

You are right but let me add that in what you hear in your HP's; you'll hear multiple blips and burps on bottlecaps and solid (hard hitting) sound on quarters. They both share the same VDI 1 to 2 numbers either way. Watch your needle. . . Its gotta be rock steady when you sweep your coil. If its wavering all over the place 10 times outta 10 it's going to be those doggone bottlecaps!

Hope this helps, good luck,

If it's a bottle cap maybe, then you whip the head over the cap back and forth and it will Break-Up or digit, and on a nickle or coin it will hold solid on the sound then you know if its a nickel not a bottle cap.
