This innovative sluice is widely known for its unmatched ability to capture hard-to-find fine gold thanks to a unique dual-flair design. Constrictions near the ramp slow water flow, then widen out to cause a quick, drastic drop in water pressure. This allows heavier precious metals to fall into the riffles and get captured where it can be recovered easily. Two-step ramp riffles capture more fine gold. Struts across the sluice serve as a bridge for rock weights. Handy carrying handles. Available: Scout - Dimensions: 20-1/2L x 7-1/2W x 2-3/4D; Weight: 1.13 lbs.
