The Keene 4505PH is powered by a very reliable GX200 Honda engine equipped with the P180 2.5″ × 2″ pump. The pump design includes a side discharge port capable of running a “blaster nozzle” to blow out bedrock and clean crevices. The deluxe 4″dredge also features Keene’s famous 3 Stage Sluice Box for fine gold recovery. The break-down four piece float and frame design has floats with step nose cut and runner bottoms for sliding through fast rocky rivers. Storage indentures in the floats provide a place for your tools, mask, rock pick, etc. The KAC air compressor provides an air supply for hookah diving (additional air lines and diving gear required). The 4505PH is equipped with 20 feet of durable yet flexible 4″ suction hose. This is a 4″ gold dredge for the serious gold prospector or even the professional dredgers. The four granite gray marlex floats and breakdown frame make for easy pack loads. Weight 215 lbs. Review Here
