This is the relic hunting program I use in Fauquier County, Virginia with my V3i with 13" coil.
Copy the default Relic program and save under a different name and then make the following changes:
Rx Gain can be left at 8 or as ground conditions permit. I usually have mine set at 4 or 5 most of the time but, occasionally can go higher if EMI permits.
Discrimination N/A (Discrimination sensitivity will not effect the All Metal mode, unless you use the mixed mode option, then it will).
All Metal 70 to 88 as ground conditions permit.
Ground Filter 10Hz High (adjust to your ground conditions).
AutoTrack OFF.
LockTrack ON.
Offset +1.
Three Frequencies OFF.
7.5 kHz ON.
S.A.T. 20.
All Metal ON.
VCO OFF.
Mixed Mode OFF.
Modulation OFF.
Pinpoint Audio VCO OFF.
