Detecting pull tabs and gold jewelry

[Tony N (Michigan)]

Don't you wish they could make a detector that could detect a pull tab and know with certainty it's a pull tab and detect a gold piece of jewelry and know for certain it's gold?
Detecting ferrous/conductivenous of an object is one thing.

One method I use, is if I find a lot of one type of pull tab, say hitting in at 65-67, I just notch 65-67 and keep truckin. When I go back over the site to finish cleaning it out I'll get the rest of the tabs but only after I've worked around them.

Edit: I wish the Deus had a quick notch feature like a minelab xterra. Swing the coil hit a button and the target is notched.

One way of achieving this would be make 2 identical programmes next door to another but have in one of them the notch of what ever you want,then all you have to do is hit the + or - buttons to change progs,it would give you some indication if its a bottle cap !! just a thought,but must admit its been years sincee i dug a bottle cap or ring pull as most of my permissions are off the beaten track for tourists etc.

I've gold detected with my DMC IIb before and would run the disc just high enough to dic out a pull tab but still hit the gold ring on my hand. Had great luck doing that.
Maybe I should notch out the pull tabs like you say.

Tony if they came out with a machine that separated the two there would be no rings to find. The dealer i bought my ML from has a tie rack in his office with hundreds of pull tabs on the spokes. However, I have a lot of gold family rings that I tested and I determined that if you notched the pull tabs that fall in the nickel range 60-65 norm on, you would only lose about 16% of the rings the rest fall below or above. Another option.

That sounds doable. The problem around here, at least in Michigan, is that there are so many different pull tabs. Maybe I should just do like I did with my DMC IIb and notch out a specific tab. Of course the IIb couldn't notch but you know what I mean.
If I'm in an area where I am finding rings, I could first use the notch and then later mop up by removing it.

A lot less harmful to depth to discriminate by tone instead of notch. And it's easy.

 

[LTimedigger]

That exactly what I meant. Notching beyond this you'll lose more but the greatest % is in this range.

I agree. I'd notch on the Deus any day rather than disc. The DMCIIb can't notch. It can only disc.

I don't think I made myself clear...........don't notch either, it costs depth. Adjust the tones to cut out what you don't want.

Well Tony,
If they did that it wouldn't be as fun.

Not to mention there would be less gold jewelry for the taking.

When you say, "do it with tones". Are you saying the things you don't want, make them a tone you recognize as the bad target?

I did some air tests today with the nine inch HF coil using the 28 frequency. I want to use this frequency to enhance my probability of finding gold chains. I used my gold ring finds to find out what the range of numbers they produced. The numbers I got were 55 to 91. Now there may be more, but I checked all the ones I had which consisted of eight karat to 22 karat yellow and some white gold. I did all this with a notch up to 40 and still got all the rings to sound off up to four to eight maybe as much as 10 inches away, depending on the size of the ring. Setting the notch to zero seemed to make no difference in depth with this air test.

Ground notch, according to Calabashs video does affect hearing the gold piece.
From what I understand, notching out certain items does not affect depth, only discing does. I'm not talking about ground notch.

Sorry, got the wrong one.

In that video he was talking about iron wrap around which is what notching 97-99 is for.

I was talking about notching pull tabs. That does not affect depth whatsoever and neither does notching 97-99 affect depth. What notching 97-99 can do is that if your deep silver coin is being driven into the 97-99 area, it may not be heard. But it has nothing to do with depth.
