Are you always digging such deep targets?

[earthmansurfer]

This was my 5th hunt with the E-Trac today and I went out with the intention of just digging deeper targets. I didn't dig anything that was lower than the halfway point on the depth meter. Today, I dug the following measured (with my Lesche) targets:
6" deep aluminum disc (dime sized) with an rusted iron ring attached.
2 coins at 6" - 1962 ish
1 coin at 7" - 1963
1 small silver medallion at 8"
1 quarter sized but thicker medal at 9" dated 1926

Most of the targets were around other targets. The short (just under 2 mins) edited video below had another coin that I dug 6" off to the side of the silver medallion and also had iron and other metals under and next to the target (I checked after retrieval).

Are you guys and gals often digging such deep targets? As I said above I was only digging deeper signals that I thought were coins. I dug the above, along with less than the same amount of trash items in around 4 hours and worked fairly slow to medium speed. (But note, I walked over many many shallower coins.) I played with fast off but trash high settings today (and deep on). I think fast off made it easier to pick out the deeper targets and still picked them out of trash. Do you notice that you still get good separation at depth with these settings? Signals were noticeably longer as well (I run normal audio response).

I ran the minimal disc pattern for a while looking for bounces down to that 27 area but it was a headache with the trash level so I moved to a slightly modified coin program in trashier spots. It was fine in cleaner areas. I did hear the "thunk" sound on one deeper target and then it stopped and I couldn't get it on film running auto sensitivity. When in auto it ran at 26-29 and so I often ran manual at 30 - was a little noisy but not bad at all, just had to check for iron falses.

I video'd all the above for when the ground is frozen but it's starting to get old filming the 6" - 8" finds, thanks for bearing with me! Looking for that 12" deep silver...

Thanks,
Albert

On average the targets I dig are between 5 and 8 inches deep. I have dug silver at 8-12+ inches deep but not as often as I figured I would be.

In my area I routinely dig deeper coins. I have what I would call good soil so it seems like the Etrac has no problem getting down there.

You don't have to LOOK for that bounce down to the 27 area it's just the line in the sand point that Andy says in his book that of all the coins he dug and of all the people who also beta tested the Etrac dug up NONE fell lower in the ferrous range than 27.

So you don't look for them to bounce or go there it's just you don't really want any ferrous reading like 30-45 or 35-45 as that is probably iron as it's lower than 27 that arbitrary point.

Also in quick mask you can see where that cursor is and if it's lower than I usually say 30 ferrous then to me it's probably iron junk same as in a more open discrimination pattern. This detector likes some discrimination but also it works better or quicker with the discrimination more opened up as it lets more iffy targets be found so you can decide wether to dig them or not. Not quite as bad as full on wide open just about all metal which in conductive multitones will drive you batty so hence two tone ferrous as you only have 2 tones a low one and a high one. Makes it a lot easier to decide to dig or not especially in trash iron areas.

Great to see you also playing with deep and fast and reporting your findings when used seperately or having them both on together.

Yes, those a re typical depths I dig targets with my E-trac.

Hey guys, I should say (cause I was asked on another forum) if I think these depths are even deep. Understand that in 9 years of on and off detecting I had found coins up to 6", maybe 7" deep - a total of 3 times or so. This includes my V3i and Omega 8000 as well as a T2. Now I get the E-Trac and in 2 weeks I have done what took me 9 years to do, around 4 times! So, I'm sorry if I'm making a big deal of 7" to 8" coins, but it is a Godsend to me and I want to share it.

ps - Any videos out there of an actual signal and dig in the 12" range?

 

[earthmansurfer]

Ask and you shall receive - Thanks Bill. With the same detector in my ground (low mineralized but high in iron mineralization) I got a large thin silver coin (hammered) that hit softly at around 7". I don't know that it would go deeper than 9" on larger silver. I imagine from my targets thus far, that a silver DMark which looks exactly the same size as a silver quarter, my E-Trac would get at a foot as it just hits silver so well. I think the difference is in the multi frequency cutting through the iron mineralization (which is nothing as bad as red clay I think.) To understand my soil the V3i measures the soil at 1% mineralization (extremely low) but -93 to -94 in iron mineralization (extremely high).

For comparisons sake, that small silver charm weighs 1.4 grams and is slightly smaller than a dime. A dime weighs 2.3 grams. 8" on that charm is pretty nice I think, especially when you see it was around 70 degrees on edge.

Thanks again,
Albert

I find most coins aren't past the 6-7 inch range. Rarely past 8-9.

 

[EtracTom-AdirondacksNY]

I agree so far too with that coin range Bart.
