Deep Fringe Coin Response

[Critterhunter]

A few friends of mine just bought Etracs and I'm gathering various info for them. One thing they could use is info on fringe depth coin response for a silver dime. Does the audio still give you a silver tone, and what kind of VDI numbers do you get? Also, what settinds do you prefer when going after ultra deep coins.

On a deep silver dime at the fringe of detection ...
The tone will be weak and it will pickalow (change tones up and down a note or two) ... not a solid lock on.
Easy to mistake it for ground noise if you are fast sweeping.
If this is what you are searching for you need to work slowly and listen very carefully.
The signal will be repeatable but possibly not from all directions if the coin is tilted a bit.

In pinpoint you will barely hear the threshold increase.

Hunting like that is very tiring work.

Willee is correct. Go for "repeatable" the most. Consistant "beep" when swinging is a must when you find such a deep target. You can play with your gain if the majority of your targets are deep, that should really help. Worn silve dimes especially barbers and seated can sound like wheats at depth. I wouldn't pass those up at all.

I agree with Willie... My assessment, especially with FAST=ON, is that those super deep signals are more broken than smooth (like the Explorer). Gotta make sure you overlap your slow swing - the sweet spot gets much smaller at max depth.

And Willie is right - I find I have to take a 15 min break after a couple hours of hunting for super deep fringe targets, because you have to concentrate so hard, it can be very mentally exhausting. Sometimes I only move maybe ten-to-fifteen feet in 2 hours!
