Hello, and thanks for this thread. I’m a newbie, just purchased the V3i and intend to tweak this machine for my area as well as experiment with all the settings and build my own programs but first with the Discrimination/All Metal mode for depth, formally called AC/DC.
I started out with the factory C/J to become familiar with the detector, went to a local school using the standard 10” DD it came with and my ear drums almost popped out of my head from all the trash in the ground. I made no adjustments, stopped searching and purchased the Eclipse 6x9 elliptical loop to include the 5.3 and the 4x6 sharp shooter. I immediately installed the 6x9; started searching where I’d left of and was amazed of the difference between these coils without any adjustments. Not only did the 6x9 help separate trash better, I took home a pocket full of dimes/qtr’s other detectors missed. I found a clad qtr 8’’ deep (I just knew it was sliver) and the dimes were 6 – 7” deep on average.
Note: I used the all frequencies mode, plucked coins next to and under trash. I did not dig trash and @ my age the V3i is time saver, if the detector displayed a cion, that's what is was including nickels.
I hope I become of some value to the thread in the near future and look forward to reading your threads.
P.S. My wireless headphones were to tight also. I just bent the wire guides out a bit and they are very comfortable now. I know this thread was going strong last year but hoping to keep it going.
