Also redesigned are the pontoon floats and pontoon frame. The 4” dredge is powered by the Honda GX200 equipped with the P180 pump for suction depths of approximately 20-30 feet. The Jet Flare and rubber damper are designed to spread material more evenly for better classification. Stage 3 riffles line the bottom of the sluice box under the Stage 2 riffles to provide recovery for super fine gold due to decreased water velocity. Stage 2 is equipped with riffles that don’t pack full of black sands and that capture gold tied up in clays. Note below that in Stage 1 the primary riffles can be removed separately from the other riffles and a new plate covered with deep V rubber matting that is also easily removable is placed at the end of the flare for fine gold recovery. Keene’s “3 Stage Sluice Box” provides excellent gold recovery and easy, convenient clean up.
