00/23 ???

[sgtm8411]

I seem to be getting a 00/15, 00/17, or 00/23 as a ferrous/ conductivity reading on occassion and it is almost always a deep target. I dug a silver canadian dime that was bouncing between 00/22 and on occassion i would get 3/28. The sound was repeatable so i dug and was pleasantly surprised to find silver down about 9 inches. I also dug a 00/23 signal to find a 1752 copper last week. The wierd thing is that if i air test these coins i dont get 00/22 or 23. I actually like this little quirk in my SE because it seems to clue me into the old and deep targets. I've also dug some old deep iron on this signal so its not fully reliable but i think im cracking the code on something here. Has anyone elso noticed this on their explorer????

I am also using digital for now... I just think with the depth you lose a reliable digital response. I am starting to dig 5/27 or 4/27 seems to be an area for smaller silver jewelry and other goodies. Found a dog tag in that range...hard to dig everything where I hunt probably would just stand in a circle...
