E-trac numbers

[Steve from Ohio]

I was wondering if anyone else is seeing this.

I was out today and the E-trac seemed to be working great. I did notice that pennies were reading sometimes 10, 11, 12 or 13 on the FE numbers depending if the ground was really wet, wet or somewhat dry. It really did not matter what year the pennies were from...I found no Zinc pennies anyway.

Does anyone know if the FE numbers are affected by ground moisture?

I read once how the moisture kind of connects some ground minerals so perhaps thats the reason.

I find the E trac is better when there is no surface moisture. I ran it a lot in the patchy snow, and it ran better when the sun dried the surface a bit. Numbers for me bounce around due to the old iron I hunt in. Surface moisture, for me, is not a plus.

Whats important is that you know the rough numerical area wher the coins fall in to and refernce this with the audio tones which should after time and experiance on the E-trac be easy to indentify.Those mid to higher smooth long tones normaly identify larger coins of copper and zinc alloy,.s

Hello Steve

 

[Steve from Ohio]

I was beginning to think that my E-trac was not working right. My finds have been only down to about 4 inches of late as compared to my first month which went down fairly deep (up to 12 inches and some even more)

I know that when I was in Florida, it was deep there too. But up here in waterlogged Ohio, almost nothing of value except clads and only down as I said to about 4 inches.

Thanks for all the feedback and I think you guys probably hit it on the head. I guess I will just have to wait till things dry out a little.

Funny, I never ever had that problem with my Fisher CZ-70 or 3D Does the same thing happen with an F-75? Does that mean that an F-75 may the the main machine for awhile until it drys out a bit here in soggy, boggy OHIO?...HH

The Etrac works equally well in very wet ground as in dry conditions and i find very little difference at all.One thing you do need to do is to adjust your sensitivity if you use manual and reduce if necessary in very wet ground.Iv found very old nondescript hammered coppers at 12 inches in very wet soil and clay.

Hi Whiggy. I agree with your recommendation of reducing sensitivity.....I often run auto in bad situations.

Just an observation on your comment :- [size=large]The Etrac works equally well in very wet ground as in dry conditions.[/size]

Could your comment be wrongly interpreted by the less experienced or new E-Trac users?

If that is intended as a contradiction of the fact that others (e.g.Coinnut, Neil, myself ) believe that saturated ground does effect detecting conditions adversely, then I question your wording.

Of course the E-Trac works equally well REGARDLESS of conditions, but the deteriorated conditions affect the transmitted and returned signal, so giving the detector poorer quality 'data' to process.

The E-Trac's excellent capabilities don't change, it was the GROUND's capabilities to mask targets that was cited, and saturated soils do indeed cause problems.

The fact is, mineralized, saturated ground,,,,boggy ground..call it what you may.....does inhibit a target's detectability if the matrix its buried in is other than 'clean' salty, wet sand..

The degree to which the ground does so, is related to many factors, some of which I've listed earlier. The target's own characteristics also play their part, as do the frequencies involved.

Interested if you can expand or clarify your thoughts on the subject.

Do you disagree with the list, or the overall suggestions?.............TheMarshall

I'm not sure about ground moisture, but the FE number DEFINITELY can change from the normal FE 12 line under certain conditions. Our $1 & $2 coins will normally came in around FE 12, 13 & CO 38, 39. Yesterday I dug two $2 coins on a beach which came in at FE 1 CO 40, I thought I must have read to numbers wrong but when I put them back in the sand they came back with the same numbers, checked the hole to make sure something else wasn't in there to confuse things but it was empty. In this case I suspect it was the minerals in the sand making the numbers come up where they did.

So I guess my advice is, DON'T, always assume that goodies will always come up on the FE12 line.
