I'm new to Etrac, only had mine for about 6 weeks, and am learning a lot from this forum. No silver yet but lot of deep pennies, so I know I have not had the coil over silver or I would have found it.
For an "Apples to Apples" test tell me if the following idea will work?
Build a Conductive Program with all the SAME SETTINGS that you are running in the Ferrous 2-Tone program. (If you use an open screen in one program then use an open screen in the other, etc). Then Save that Conductive program next door to where you have saved your Ferrous 2-Tone program. Next, load you Conductive program into your QUICK MASK and your Ferrous 2-Tone into your Digital Screen.
With a quick touch of the Quick Mask touchpad you can go from one program to the other. When you get a good signal on a target in Ferrous 2-Tone simply switch to Quick Mask (Conductive Program) and rescan the target to see how it sounds or TID's in that mode.
Hopefully this will be a true "Apples to Apples" comparison.
I've been using Ferrous 2-Tone for about a week now (with Fast ON, Deep Off, Varibility at 30, Sensitivity at Auto + 1, Threshold at 18, Volumn limit 30, Volumn gain 22, Response Normal, Trash Density High, Ground Neutral. I Blacked Out the bottom of the screen up to Ferrous 22 so as not to hear as many Ferrous Sounds (as I was hearing too many very small ferrous objects). Now I hear fewer ferrous sounds but I can still hear High Tones when I cross a conductive object. In the past week of using this program I have heard (and dug) about 200 coins, (memorial pennies, nickels, dimes and quarters, wheat pennies, buffalo nickles and a silver ring). Most of these were found by hearing a LOW TONE AND A HIGH TONE under the coil AT THE SAME TIME. I criss-cross those signals from 2 directions TRYING to PINPOINT THE HIGH TONE . When the hole is open I use my Sunray X-1 to find and remove the ferrous object if necessary in order to find the coin. While probing the open hole the Sunray X-1 lots of times will seperate the ferrous from the conductive although many time I have to remove the ferrous object FIRST in order to hear the coin. I have found as many a 4 coins in the same hole after removing the rusty items.
I sometimes use a Very High Discrimate program in Quick Mask (blacking out EVERTHING but pennies, dimes and quarters) to rescan the hole before digging. Many times this Discrimate program WILL NOT HEAR a signal (probably because I have it set so high) on the same target as Ferrous 2-Tone.
I use the TID numbers in Ferrous 2-Tone to tell if I am over a pull tab or coin.
I've had good luck with this method so far, but still NO SILVER, yet I know it will come WHEN I GET ONE UNDER THE COIL.
This is just my inexperienced opinion being as new as I am, but I hope you will try the "Apples to Apples" test and post the results.
Thanks,
Kenneth
