12 kHz
Reactivity = 3
Silencer = -1 or 0
Disc = 2 to 10
Iron Vol = 0
Sens = 93-95
TX = 3
Audio Response = 3
Overload = 1
Notch = 00-50
GB Manual...3 points BELOW average GB readings
Ground Notch = 85-90
Set breakpoints (if not using full tones) for nickel<dime<quarter targets. I think US nickels in 12 kHz read 52-54, dimes 88-90, and quarters 92-94 if I remember correctly (I've really gotten used to 4 kHz VDI readings)
12 kHz for faster recovery vs 4 or 8 kHz, reactivity = 3 enabling a fast swing speed, {TX = 3; -3 points GB from average; Silencer = -1 or 0} for easier "hooking" of targets at the edge of the coil. Slightly offset manual GB enables a little more sensitivity without falsing.Notch of course ignores everything else non-ferrous...Will there be seeded trash targets as well? Or just the coins?
Basically this is the Deus Fast program except you would be using 12 kHz. Iron Vol is at "0" so no iron distractions. Ground notch will help if you bump the coil on a tree root, or stubble - enabling ground notch seems to further quiet the machine when it's run nearly wide open like this, especially in TX = 3
Good luck with the hunt and as always - we want pics!
