Just a thought, since Kalifornia has banned suction dredging in these Northern Rivers and streams, and since there is known gold there, is there a way to detect in deeper water for nuggets? Just wondering about all those guys who can't suction dredge anymore, but want to get out to the deeper spots where they have been finding gold,and because gold is now so high per ounce, this might be a viable way to continue the hobby. Once I heard about a deep water system, but don't remember the specifics. Any ideas, guys? Thanks, BoomLover
