Well, my Omega does have depth.

I can't tell you how many times I've doubled and tripled checking the same hole and found
more coins using my Omega.

When you do your re-check do you change any settings or just stick with ones that found the first coin?

While I'm not the original poster, I read his reply and felt the same way. Actually, I felt the same way when using any decent slow-motion, quick-response and fast-recovery model such as the White's IDX Pro (modified) with the smaller 6

Cal..the 11DD gives a great response to stell bottle caps, but then so do other detectors when you use a DD coil. If I know tht I'm going to detect an area that has, or is likely to have those bottle caps, I use the concentric coil...it still picks them up but does tell you what they are by the variation in the VDI response. You only need to detect a few, watch the numbers and then you can work it out. There are times when I do check to make sure it's not two coins of different denominations right next to each other. Generally, the concentric coil is much better on those pesky bottle caps. HH

Hi Jim,

I too like to find the older Buff, V and Shield nickels. Unfortunately at older sites very few give a classic nickel ID due to co-located iron/trash and or the nickel alloy itself. As Gatorfan noted in his post a while back the Shield nickel he found (lucky him!) did not lock on, giving a nickel tab range bounce, While I have dug a few that locked on s TID reading they also tend to read much higher than a 'normal' nickel. Recovering targets that give an inital bouncing reading, especially those that settle down a bit when well centered on repeated sweeps is what I have found to be the key in locating these older nickels.

Higher frequency detectors such as the MXT, T2 and F75 may lock a little better on old nickels but they can and will give readings much higher than normal.

While not fool proof your method of ID'ing bottlecaps works for me as well. To take it a bit further, on shallower relatively loud hits, sweeping the tip of the coil an inch or so off the bottlecap should give an iron reading while coins will still read as non-ferrous albeit a much lower reading.

Those deeper softer hitting bottlecaps are still dug but using this method saves a lot of time on the vast majority I run into.

Jackpine, its not so much that my Omega doesn't find and id nickels quite good, but tab tales, can slaw pieces, ect. also lock on and id as nickels as well. Seemingly more so then does my F 75, 75 LTD and cz3d. I find I am digging more of the trash items then I did before. However, having said that, I have also found several nickels with the Omega that I flat out missed, for whatever reasons, with those other detectors. A couple with the Omega also had some decent depth for making a pretty good id to dig. HH jim tn

Txquest and Tom Z thanks for the steel BC tips

The site I was at that's infested with bottlecaps is an old park that fairly routinely gives up Barbers, and once and a while a seated sqeaks out of there, but the bottlecaps in this particular part of the park are really masking a lot of stuff.

How is it that the Explorer/Etrac isn't affected by them?

Most of our recent mid and upper range Teknetics and Fisher metal detectors use a signal processing algorithm which is very good in many ways, but does "like bottlecaps" a little more than some other ID algorithms. Not that the steel bottlecap problem is unique to our machines, most modern VLF machines exhibit it to some degree esp. when using a DD searchcoil.

My personal steel bottlecap trick is to turn the searchcoil into the vertical plane and sweep all the way across the target. A coin will usually give a double hit and will usually ID both hits in the range which is normal for that type of target. In other words it will usually more or less agree with the ID you got will sweeping over the target in the normal manner.

Trash of irregular shape will tend to depart more from the ID you got in the normal sweep. Steel bottlecaps will usually ID down into the iron range when you do this.

This technique works better with smaller searchcoils than with larger ones.

I haven't tried it on machines of other manufacturers but I would guess it will work with most of them also.

The detector's that hit those caps will hit a Confederate tin back button with ease....and the T-2 loves them No problem if you're relic hunting in the Deep South back wood's!!!

Suck's if you are in a park looking for coin's though

Thanks for the excellent info, Dave. My best, and great to see you posting!

How deep would you say the 90% rotation works on this technique?

The reason I ask is I have dug partially masked deep coins, especially with the F75 LTD, that do not give solid hits at a 90 rotation.

Most of our recent mid and upper range Teknetics and Fisher metal detectors use a signal processing algorithm which is very good in many ways, but does "like bottlecaps" a little more than some other ID algorithms.

When I get a target ID and could either be a bottle cap or dime, I put my
Garrett Pro Pointer to it and if there's a broad strong signal I know it's a bottle cap
versus the dime signal which would be a smaller but strong one. Saved myself
from digging the bottle cap.
