Dr. Sluice The Hybrid Sluice - Drop Riffle Sluice Box

The Dr. Sluice The Hybrid Sluice is a drop riffle sluice box for gold prospecting that combines the two earlier Dr. Sluice designs in one longer box. Behind a larger indicator mat it carries several of the deep, wide troughs from The Original and the shallower, narrower troughs from The Prospector, so one sluice handles both heavy throughput and fine gold cleanup. It is molded from 4 mm plastic with two 3 mm stainless steel braces, measures 31.5 in long by 9 in wide by 4 in deep, weighs 2.15 lbs, and runs classified or unclassified river gravel. What the mat and the two trough shapes do in use Larger indicator V mat at the head: It spreads a shovelful across the width of the box before the material reaches the troughs, and it shows you color early so you know the feed rate and slope are right before you commit the rest of the bucket. Deep, wide troughs from The Original: These sit first behind the mat and take the bulk of the heavies, so the box can run for a long stretch without clogging or needing a cleanup. Shallow, narrow troughs from The Prospector: These sit further down and catch what the deep troughs let past. They hold less material, which keeps the cleanup concentrate small and makes flour gold easier to find in the pan. Deep side walls: A surge in the creek is less likely to wash over the side and carry the concentrate out with it. 4 mm plastic body with two 3 mm stainless steel braces: At 2.15 lbs it is light to carry for its length, and stiff enough not to flex when it is loaded with wet gravel. No riffle hardware, no matting to lift: Cleanup is a matter of tipping the box into a bucket and rinsing the troughs, with nothing to unbolt or peel back. What is in the box The Hybrid ships as the sluice body and braces fitted. It does not include a stand, classifier, pump or carry bag. If you feed it with a pump rather than a shovel, any small 12 V water pump works; we stock pumps, classifiers and snuffer bottles in our old prospecting equipment collection.
