EQ800 Silver Dime TID Variances

I thought this was interesting. I've noticed that a U.S. silver dime will TID spot on at 25 when either air testing or when at shallow depths. BUT as the coin gets deeper, the TID goes up. I've seen anywhere from 27-32, the deeper the higher.

This phenomenon along with the additional modulated audio at depth, and frequently loss of pinpointing, will almost always result in a deep (9" or deeper) squeaker silver coin for me. Once I understood this pattern, I'm personally okay with that, I actually even prefer it that way because when I get a target with these conditions I have a fairly high confidence it's going to be a silver coin at good depth (I've observed similar results on deep silver quarters as well).

Are others observing the same phenomenon?

Same with 8-9 inch wheaties also. They usually bounce from 23 to low 30's. Had a barber dime hit the low 30's once, and assumed it was a wheatie till I saw it shining in the hole. I'm like you, when I hear that deep high tone I'm 99% sure it's a coin.

Funny you bring this up.

I was watching this very thing this last week, but with clad dimes.

I was experimenting with some of Tom D's newer Fe2 settings in a known park environment, 3 separate outings, 3 different locations.

Shallow clad 10¢ are right at 25 on my 800 with the 11" coil, but as they get to 4-5-6", start to upscale into high 20's to 30-31; occasionally higher.

Target ID is flighty rather than a steady climb. This is with a sample size for this week of 20 clad dimes found in the field. I had 1 Merc right at 5" that was the same, ID between 25-31, flighty numbers, but the audio was correct. (50 tones)

Interestingly, and here is what throws me, deep nickels HOLD to their TARGET ID in strong fashion.

I popped a war nickel at 8" that was 13-14. Solid ID. Most nickels come in 12-13 for me whether deep or shallow and the depth give away is the modulation in the audio.

Not sure why the difference in the lower (nickel) conductors giving a solid yet as i work my way up the conductivity scale, the target ID varies.

I'm interested to read theories here.

Just one more good target before I go.

The tell tale audio [50-tone] combined with the modulated audio is a tell tale sign of a deep coin, and the real fringe whispers have no pinpoint, love those kind of targets.

Perhaps Tom D. can shed some light on this phenomenon??

I'm not saying it's a bad thing, personally I like it, I think it sets it apart from other machines by providing more data, and this data set is a good one IMHO

Brian, absolutely. Your description is spot on, to exactly what I have observed, and it's exactly what I look for when trying to dig the deep dimes (in other words, the ones that Tom_in_CA things are only able to be located with an EXII!)

But seriously, what you describe is exactly what I have learned -- perfect air test on these silver dimes (as expected), but then ID numbers (and audio tones of course) going higher the deeper it is, with deep ones bouncing upper 20s to low 30s. That plus the modulated audio giving a tell-tale, soft but clear sound...absolutely.

And yes, 67GTA -- some wheats, especially the newer ones -- do the same thing. The really old ones are more likely to give me lower tones/VDI -- even into the IHP range at times. But the newer ones can read well into the 30s, when really deep.

But I totally agree with Brian -- once you learn this, it's fine; I'd rather have them up-average (farther into the "big silver" range), than down-average (into the pulltab range)!

Cal, I have started typing this a couple times in past 3 weeks, deleted, started again....same sort of thing with my Nox and deep items.

2 deep barber dimes in the past 2 hunts that were on the edge of detection.. IDs were jumpy but all the way to low 30s. i commented to ozzie on the phone on the way home that it means i have to go slower in huge fields...good bye to coverage, but ill take it if i keep getting barbers.


ground moisture distorts it even more, i think.
at my jewelry hunting spot, got two deep silver rings..not lunkers, but pretty thin. down near the waterline (fresh water spring) where the ground is always sopping wet, the IDs in the ground were both high 38 and 39s, with some grunts...they were both very deep, and I have missed them with f75, cz, mk, g2, everything else...so not complaining. its the tone that stops me, and i really try not to look at the IDs at all when looking for deep items. I almost think that even if i hit them with f75, i would have discounted hearing both the grunts and IDs that high as iron wrap around.

Mr Cobra-Cal Brian : Does this FINALLY mean you will duel with me in the turf ? C'mon, bring it on buddy ! Let's head to SF or Oakland to some known deep-turf-duel test zones. Ya ready big buddy ?

Clearly you didn't read my disclaimer

Primary reason for the up-averaging ….. is mild-to-medium dirt mineralization. In particular..... oxides of iron.
If you air-test a silver dime with the EQX...…. it (mostly) will not up-average.
Also...…. there is a slight propensity for higher conductors to have a greater (larger) percentage of up-averaging.

(If you have medium-to-high mineralization...… the tables turn...…..,,,,,,,,, and ALL non-ferrous conductors will down-average...…..right down to 'iron' readings).

C'mon, admit you like angling for merc's more than those pesky seateds and gold coins. C'mon , I'm calling you out !

But seriously now : Turf is a "sport unto itself". There's something fun about the strategy involved. But yes, it's not the way to bag seateds or relics in CA, for the most part.

all sites are open,EXCEPT "sidewalk easements"
you guys will be too busy "shoveling piles" to detect!
