OK Andy...Here's One...Anyone Else Notice This About The E-Trac?

[unearth]

I've noticed something about my E-Trac that I have a question about. When I get a low conductor sound that sounds good and looks good, digitally, when I pinpoint I notice that the cursor bounces to a different line than the F 12 line. So far everything I've dug that has a low conductor sound and the cursor bounces around has been junk. The good items, gold and nickels, is when the cursor doesn't bounce while pinpointing, BUT some gold and nickels have come in on the F 11 or F 13 line. But the cursor was still a constant and not bouncing.
So, my question is, is it a smart idea not dig items when the cursor bounces around, with low conductors, or do you think I may miss something good?
Thanks,
HH Gary

If you see a slight variation in Pinpoint vs Motion mode, that is expected. Typically what I have seen is when you get a signal, go to Pinpoint and the FE value drops into the 29 to 35 range, you can virtually be assured that it is ferrous junk.

When you say the cursor bounces around on a low conductor are you talking in both modes or just in pinpoint. If there is anything in the area when you go to pinpoint, the reading will move around based on what you are moving the coil across.

The cursor bounces when in detecting mode, not in pinpoint mode.

Hi Andy, hello Unearth!

Try this......Pin-point the iron, take it out.....

Now go back and get the good target that was being masked...????????? No...????..............TheMarshall

Very few detectors can lay claim to that feature. Boy has it been handy.

Marshall-
My quick mask is set at F 27 Thru F 35 disc out, plus a little more at the bottom right to disc out the nails. I use no discrimination on the C side. Normal pinpoint; gain 20; deep off; fast on; variability 30; limits 30; sounds multi.

I hope I've explained my inquiry correctly. If I didn't, please indulge me while I try again.

While detecting, the cursor, at times, bounces around with a low conductor sound. When I pinpoint the cursor will stop somewhere else except on the F 11,12 or 13 line. Do I dig?

So far my gold and nickel finds, the cursor did not bounce while detecting. The F line was a solid 11,12 or 13 while in the detecting mode. When pinpointing, the cursor didn't move, it stayed on one of the lines mentioned above.

Thanks for all replies to my query

In pinpoint mode, the Etrac is in all metal (ignorant of all your settings) and will lock on to the strongest signal under the coil. So if your target is a coin on edge or deeper than the iron trash, or smaller than the iron trash it is next to, and you are not perfectly on top and centered over your intended target, your ID could be jumping from one target to the other (trash) and make the two separate ID's look as though you are having one target ID bouncing when you are really seeing both ID's and thinking they are one. Marshall's advice on digging the iron out first and going back over is the best way that I have found. I don't really mess around with pinpoint in trash unless I am using a very small coil as it is for me seldom effective, slow, and very misleading at times. Especially if I am using high trash on, many times the target I am hearing is only because the high trash setting is causing the machine to lock onto the weaker signal not disced out and as soon as I hit the pinpoint button it is as if high trash was turned off and now I only hear the iron, even though the good target is still present, but now being masked out by the accepted iron signal in pinpoint.

Hello Gary, and all following the thread.

Let's imagine we're using your settings......(I don't think you need the extra 'naily' bit on top of a F3 35 to 27 reject).

I AM USING FERROUS AUDIO...AND ...TWO TONES.....(Please try both together).....Why???....Highly conductive iron doesn't fool you, as in COND mode.

ANY AUDIO THEREFORE MAKES ME STOP.......... AND WORK THE TARGET.

WHY??..BECAUSE YOUR IRON-MASK OF Fe35 to Fe27, SHOULD KILL 99.9 OF IRON, [size=x-large]STONE DEAD,...NO AUDIO WHAT SO EVER.[/size]

The audio is the MASTER clue.....any evidence of REPEATABLE tone...high or low.....is trying to tell you that there is something there other than a ferrous target.

Even if it's broken sound....AS LONG AS IT IS REPEATABLE.....get stuck in.

Try locating target in "motion".....then in PIN-POINT. They may/will differ in position if iron is a few inches away from a good target. (Re-read DIGITRICH's post)

PIN-POINT is ALL-METAL as DIG correctly stated....PP will prefer to lock onto the iron.....SO GET RID OF THAT FIRST....but take care to check the spoil-soil

whilst you're doing so in case you incidentally disturb the good target nearby.

Once you've positively removed the iron.........sweep and find the good target....

Come back if I've not explained things in an understandable way............TheMarshall.

Thanks Marshall, your explanation was clear. I'll give your setup a try.
Thanks to all for responding to my question.

P.S. The Fe reading can go from the normal Fe12 to any value up to Fe 20 or more.....watch the cursor banging it's head on the iron mask boundary.....(good clue...MIXED TARGET)

AND.......notice how it actually drops into the Black at Fe 35 Con 50 (for example)...when in PIN-POINT.....it's locking onto the iron.

DON'T take that as the total picture.....It's Just the 100's of times greater dominance of iron....GET IT OUT...
