F70 new coins verses old

[podojils]

Through several months of trying to adapt to this new detectors style, i seem to be getting alot more familar with its sounds, and am starting to pinpoint finds much more accurate, but i sure seem to be finding way more new coins rather than old. I have been detecting really old areas that should have older finds, im not sure if im skipping these finds by not digging the right signals???When i have a strong signal, and also have a good pinpoint signal, i seem to find only new coins, should i be digging lighter ,choppy, or bouncing signals also.

Firstly, to avoid the critic killers, I love my F70. I've found some very nice coins at relatively shallow depths. But I have a similar problem in that there seems to be some sort of light-switch feature that just shuts down anything below 8" deep. This despite the fact that I've found good targets that id'ed excellently up to 8" deep and not even with the unit cranked out. I cannot get a good read on any target below that magical depth unless it's iron.

I can hear targets below that depth with AT or pinpoint but no ID info comes through in those modes on deep targets. Two days ago I was with my buddy who asked me if he had a good target under his ETrac coil. He was getting erratic reads and no reliable data. My F70 told me it was high coin, most likely a dime, on edge at 5" and I told him this. He dug down and at 5" he got a 1916-S merc standing up in gravel. Half hour later I checked another target for him, could not get any good numbers on it myself but in AT and in pinpoint I told him two targets near each other, no good id. Both were early wheats at 5", Flat orientation and no junk in the ground above or within half a foot. I'd dug multiple mulit-coin spills at the site already and got good reads on all of them, usually in the mem cent range even though they contained clad quarters and dimes as well. I was getting clad and wheats all week to almost 8" but nothing deeper.

A couple weeks ago I scored an 1857 seated dime at 5", slanted in roots amid lots of .22 brass, in highly mineralized ground. Clear as a bell signal too.

Using the 11" DD coil, settings were disc 21, sense 90-99, thresh 0-3 3H tones and notch 1. Tried going Disc 0, max sense and thresh between 3 and 9 also, nothing deeper than 8" showed up. I wouldn't complain except the guys I hunt with are using Garrets, White's and ETracs of course, and are pulling deeper coins with the exception of the Garret. Last point, was trying last couple days SL mode and DE Mode on everything I thought I heard grom the deep, SL just gave me more small junk to look at, not deeper stuff with good reads.

I have found that the IH's range more widely than any other coin and it seems their numeric readout value goes down with depth/age. Silver dimes and quarters read a couple digits higher than their clad counterparts also. I've only used the big DD coil and am somewhat confident the smaller coil will not get better depth. But for those of you who know, will the concentric coil go deeper? I know in the ground I'm working now that the deepies would not be hiding from me if I still had my CZ-5 or CZ-7.

Now for some eye candy.
