[QUOTE="oldtimerROB, post: 626732, member: 8947"] Hi ronnie, surprising about the discrim. modes not picking up the signal. I used to constantly test the machine at 20 Khz on a 3/4 inch long gold specimen I have and in D12 it goes 5 inches deep compared to AM 3 inches deep. I intend to persevere even after 40 hours in the field coming up empty handed as I remember it took me 6 moths to find a small specimen back in 1980 defecting every weekend at Wedderburn. I got a good signal on a 3 inch bent nail in the DEEP mode 6 inches deep at Inkerman which I think was steel and tried to mask it using the tone break and placing it alongside my specimen on the ground and at one setting around 20 the gold and nail were both masked. I adjusted the setting slightly and the nail was masked but not the gold. I would not recommend doing this normally. All tin foil and silver foil I found at the diggings and at picnic areas surprisingly came up at 18 ID in D12 and it is easy to mask the foil and not have to dig it up constantly. [/QUOTE]
