Gold prospecting with Audrey, Nikki, Robert and Chris at the LDMA property in Athens, Michigan. May 25, 2008. This is a water powered trommel. It easily breaks apart into two pieces- 42lbs for the top unit and 44lbs for the bottom. The drum is 3/16 stainless punch hole screen. Material classified out the front of the drum is moved to the side tray with its own water supply. Great fine gold recovery. … honcoop highbanking gold prospecting trommel turgo water wheel panning …
