Electric Submersible Suction Portable Dredges 2",3",4", for Gold and Diamonds Prospecting and Mining, Silent, 29.6V LiPo battery - details see: https://www.machineto.com/portable-suction-electric-dredge-10311715

Suction electric submersible dredge

Ventury action gravel processing machine for gold in-stream mining and prospecting

• Very Handy Suction Dredge can be used for prospecting and selective mining for remote accessible areas.
• Comes with stabilizer buoyancy tank
• Dredge has advantage of low weight (3-inch weights 9Kg compared to 3-inch floating dredge weight 70 kg)
• Not noisy at all
• Runs completely under water.
• Can be used with electric Hookah compressor for deep diving operations
• Not producing any dangerous exhaust fumes compared to fuel motor powered dredges
• Easy switch on /off operation.
• Best gold mining tool for beginners and professional miners
• Stainless steel suction nozzle and riffles - dredge can be used in marine water
• Easy cleaning process with just tip over in plastic container makes dredge very efficient for quick hole test
• Know-how special jet and box design increase suction and volume of running water
• Li-po battery comes in waterproof and hardproff box

It has never been so easy to be in gold hunting ever.

Stabilizer buoyancy tank used to hold the dredge in a vertical position and regulate dredge angle for maximum gold recovery. Try to avoid side tilting of tube to prevent gold loss. We recommend also to empty dredge every 1-2 hours, it reduces fine gold loss and occasional tilts loses.

During operation we recommend frequently using the on /off switch. It will last battery running time and increase pump efficiency by cooling off the electric motor.

Dredge has improved riffles design with a woven wire matting system separating all fractions gold.

For quick cleaning process just tip over the tube in container with water, it will make the dredge very efficient for quick hole test.
