E-TRAC TDI Numbers

[Mike K (Ohio)]

As a new E-Trac user I have looked at the above link about TDI numbers for coins that were air tested and was wondering if you guys that have had many hours under the headphones would be willing to share what numbers come up on your deep coins be it silver or copper? I'm just trying to cut down the learning curve and I'm sure it would help lots of new users I know the importance of listening to the tones but as much as everyone talks about looking at the numbers it would be nice to know what people are seeing on those deep coins Thanks ahead of time....

Mike. For me and my area the IH's will hit Co34-38, Wheat's typically 41-43 with an occasional 44 and in the right conditions 45. In dry ground the Barbers and the Seated coins (especially the more worn ones) will come in like a wheat until you start getting closer with the probe then they get more silvery sounding. Merc's, SLQ's, Rosies, Washingtons, Barber quarters will typically be 45-48. Newer shallower clad quarter will be 48 and then the closer you get to it with the probe will jump up to 49 and 50 (which in my disc. pattern I have 50 disc'd out so it nulls.....can be frustrating).

Funny thing is I can't think of too many good targets coming in at 39. Nickels for me will range 10-17....however the majority are smack on 13 and 14 Co numbers.

Let me say this though. If you're in an area that is producing the older (pre-1940) coins. I honestly would have a hard time letting ANY repeatable/diggable signal go if it is in the same depth range.

How about the FE numbers? How low will they usually go and still be a coin assuming there is not any iron around?

LOL, that's funny. I don't think I have found any site other than a farm field that wasn't loaded with iron. the E-Trac really lets you know just how much junk is there that the other machines don't register. As for the numbers, I haven't seen iron affect the numbers much. Your CO will stay pretty much just where you expect it. Your FE can be all over the place. look at where it hits MOST of the time. If there are a lot of 12 - 14 FEs, it's worth a dig. If it's mostly 20's, it's most likely junk. Also, iron falses will cause the FE # to jump back and forth from the 01 to the 20's a lot.

The best way is to use your ears, and eyes (without the screen). Listen for a repeatable signal. Look to see if it is signaling over the same spot, or jumping around. If it sounds good and is repeatable, check the pinpoint. Last check is to see if it pinpoints where is signals. Got a "yes" for all 3? Dig Dig Dig!

Fe's can be all over the board. The last two weeks has been a little strange for me. Hunted 2 parks. The first I'd only pulled a silver war nickel and kid's ring...until last Sunday. I managed to pull up a Merc. It was the first ever 1 way hit that stayed right at 27 FE number. Almost all the time that will be a bent nail or something.

If I can get it loaded this week, I'll show you our park hunt from today. We did a number of full digs and show how the Fe numbers were also ridin' in the 20's, yet we still got coins.

Consistency of signal is the number one importance. I'll dig iron if it give a consistant signal within my discrimination pattern.

Yes I'm learning that the FE's can be all over and the CO's are a little more consistent but I still haven't pulled any silver out with this E-Trac and I believe it's just never been over it.. If I was back home in Ohio I have to many places to hunt but here in Washington just haven't found a places yet...

Mike, i don't believe you put the coil over it yet. The silver will stop you in your tracks "the tone". The high tone of silver is higher than the high tone of a clad dime or penny. Once you've dug a few you will know that tone. I wouldn't take to much from other peoples numbers. Soils differ from place to place and day to day in the same areas.

well for me indians are normally 34-37, I have found 82 this year and I think one was 31, was was 32, rest were in 34-37 range

wheats are 39-42, seems like older ones are 39, 40, and the newer 1940-50s are 41-42

nickels are literally all over, lowest I had was a sheild nickel at 06-08, and a buffalo was 08-08, most are in 10, 11, 12 range, some as high as 17 especially war nickels

rosies and mercs almost always are a solid 12-45, seems they flucuate very little, clad dimes are 12-44 for me 99% of time

barbers, for the most part are 12-45, I had one really worn one come in at 12-42

the one capped bust dime I dug was super smooth and in TTF it still read 12-45

clad quarters almost always 12-46 and 12-47, silver has been the same for me

I have only dug 4 silver halves this yr, one was all over, one was a solid 12-47 and other too were both 6-47 (the two I dug side by side)

Great info. Just what I was looking for real digs with the numbers Thanks Terry..

great topic, this will help me as well.
thanks!!

edit: just realized how old this topic is..... how much did the info on here help you Mike ?
