[QUOTE="Goldpick, post: 93142, member: 1695"] It is a bit of a misnomer that running with high sensitivity is ALWAYS the best setup for detecting deep, for low mineralisation and low amounts of junk in the ground, it may be possible to crank it up a bit more. Have the sensitivity too high, and the detector will pick up "everything" in the ground including mineralisation and abundant small junk targets. You are better off lowering the sensitivity to the point of having a stable background threshold, and you will find the more prominent high conductors will still come through, and be clearly distinguishable from all the bits of iron and foil in the ground. This is especially a common mistake on the beach (wet sand), and for gold detecting where background mineralisation or salt will make the detector false and become unstable if set too high. Every area detected will be different, so be prepared to readjust sensitivity to suit. :) [/QUOTE]
