Personally I would use reactivity 2 or 3 18 kHz,,full tones,,run my disc around 2.5 with 9" coil,,,11" coil around 3.3 on the disc.
Reactivity setting of 4 help in places,,,listen for the super short tone.
Silencer -1 for all hunting.
If no Deus has been there,,,it should show pretty quickly.
Dig based solely on the tone,,,forget the meter readings.
If over clean ground adjacent to site,,if these suggested disc settings seem to be providing too much ground noise,,raise them just a bit.
11" coil should be the one that gives trouble if one does,,moreso than the 9" coil.
