Yep dialing back sensitivity in thick iron is a classic technique some call "sifting" and I have recommended doing it on both the Deus and Equinox. Yes you will lose some depth, but you are not worried about depth in thick iron, you are trying to make that shallow, masked non-ferrous pop out of the muck. Calabash is a pro at doing that. He is also dead on regarding how hot this detector is. Need to not be afraid to quiet the machine down by dialing back sensitivity. As I say, the deal with Equinox is to get it to run on the edge of quiet so you are maximizing the signal-to-noise ratio. HH.
