I thought it might be helpful as a coil check but to also see the effect ground mineralization and EMI have on the V3i.
Stock coil, Rx10, Disc 95, Recovery Delay 60, Filter 5 pass, 3 freq. Best Data, No ground balance on the below numbers (it was on auto trac, oops).
0.3 % EMI (perfect)
Air Test
Coin (Clad) VDI Depth Notes
Quarter 83 13" relatively fast swipe, slower swipe gave me 11"-12"
Dime 78 11" 9" depth when swiped slower
Penny 54 12" 10"-11" when swiped slower
Nickel 19 12" 8"-9" when swiped slower
Ground test - I don't have anything really in depth regarding maximum to report. Would be nice to note some of your deeper finds here along with the pertinent info.
I can easily hit a non silver dime at 9" using the above settings and with 9% ground probe reading.
I can easily hit a silver dime sized target at 9" using Rx 8, Disc 90, Recovery at 65 ish, 10Hz band, 3 freq Best Data, auto trac - clean area of ground. I could also hit the target with the Deus program (85 disc, recovery delay 20, same other settings) - I was shocked it was so deep.
I would venture to say the max is probably quite a few inches deeper if I change the settings.
Suffice to say, I have a good coil
