[QUOTE="Fox, post: 93723, member: 2991"] In reply to Joe's post I have just done a bench test with my ATX using the standard DD coil on various sized bits of gold. I generally run the following settings: Disc = 0 Vol. = 7 Sens= 11 Thresh = 6 - 7 I find that the signal response and depth is affected by the shape and solidity of the gold particles, for instance a 0.1gm flat or chunky piece is picked up more readily than a 0.3gm wiry or porous piece. Results are as follows: 0.05gm solid = 3cm 0.10gm flat = 5cm 0.20gm flat = 7cm 0.30gm porous = 3cm 0.50gm chunk = 8cm 1.20gm chunk = 11cm 3.10gm flat = 16cm 23.4gm speci = 22cm ( apx 50% wt Au ) Have been following posts regarding the ML Sdc2300 which seems to be kicking butt on subgram gold at impressive depths in heavily flogged areas. In theory my ATX should do the same with the 8" mono coil. [/QUOTE]
