Hi Ron.Not sure what your asking.Ive run the V for almost a year and have used the deep silver program a few times.This program runs mixed mode (discrimination & all metal) and can be tricky to interpret.The all metal is going to sound off on all metal targets,while the discrimination mode is set to +65-+94 (in the stock program anyway).This program is somewhat of a balancing act so to speak,because depending on the ground you hunt in,if all metal is reading deeper than your discrimination you may get the all metal signal with no discrimination sound off and vice versa.The few times I ran the program I was fooled by rusty nails more often than not.I have more experience running the 3 freq. best data for silver and have found on deeper silver the VDI can vary considerably when sweeping over a suspected target,but will for the most part stay up in the 80s VDI range.It seems,usually when I get a good repeatable signal,sweeping side to side over a suspected target,it will seem like a solid silver signal.Then when I go to pinpoint,if the pinpoint is strongest off to the side considerably of the suspected target,it seems more often than not its been a rusty nail.Has anyone else found this to be the case?
