We are proud to bring you our excusive Revolutionary Hand Dredge As seen on TV on the Outdoor Channel "Gold Fever" film 81FG "This sand pump actually really works. It has a diaphram check valve built into the bottom cap. This allows you to suck gold and sand from under a rock in a stream and transport it to your bucket or sluice without loosing any of your sample. It will suck sample out of a three foot deep hole and not loose any of your gold. I also have a crevice tool that goes on the end of the "Gold Trapper" and extends it a little over a foot to let you suck out the cracks in the bedrock or work your way through the big rocks in the bottom of a hole.", Chuck Cummins. Chuck guarantees the workmanship and the materials of the "Gold Trapper", when used under normal use, for a year.
