Sadly, presets are not very deep but good for building your own programs

Higher reactivity means better in trash, lower more depth, always lower silencer to minus 1

I think most programs have audio set so deep targets are softer, this may help you tell if it's deep or shallow?

Clear open, non mineralized ground I run reactivity as low as zero, Ilike 11.7 but silver coins may do better at 4 or 8 kHz

Time and patience along with help on here and you should love the Deus.

I like Andys book, explains what features mean and do.

I really like the instruction videos that Gary does, watch them over and over, happy hunting
