Works great for pulling gold bearing material from behind rocks and out of holes. Works in water up to 3 ft. deep. These have a 3" bore with a 2" nozzle and a 3/4" crevice nozzle and can move quite a bit of material. Lots easier than a shovel, faster & more efficient.Suck material up and deposit in a pan or a sluice box in the stream and get another load. Its that easy. New $85.00 or $95.00 with crevice tool.
