[QUOTE="Roscoe, post: 92695, member: 1615"] Karl, most people reiterate Mono vs DD depth advantages from books, experts etc. I have never seen a gold in situ test between the two and I have never done in ground tests between the two. By design a mono should go deeper, but if that mono coil is running noisy and one has exhausted all options to control the coil (smooth threshold) then you would have to change over and run a DD coil? I have seen on the web, Air tests, test beds comparing the two. These tests give some idea, but there is no substitute for real digs with gold in situ. I know a bloke who dug 4ft down for a oil filter once and it was all caught on camera. I don't blame him though his wife scoured a 26 oncer in the same area the day before. :) [/QUOTE]
