Explorer 23 River Sluice Box



After many requests from folks around the world, we have finally finished with the testing of our latest design. With the smaller expanded metal and the rod riffle design, all incorporated into our Alluvial Sluice Box Design, we have created a sluice that is ideal for running smaller gravels. These units are perfect for beach boxes and streams with fine gold. These sluices are intended for classified 1/8″ material and smaller, while still handling material up to 1/4″. These are available with either rubber matting or carpet.

The sluice is 23” long (30” with flare) 8 1/2” wide with 3” tall sides , and weighs 15 lbs, 15 oz.

Inspired by Mother Nature

The Explorer 23 River Sluice Box takes advantage of a continuous slowing of the water current, causing more gold to deposit out, increasing your efficiency, giving you back more time for fishing, hiking, drinking, what have you.

We started by trying to improve our methods of extracting the gold from our concentrates. After about the 10th generation of sluice, we settled on our unique design.

Our design in different from the other 98% of the sluice boxes out there that are built straight. There is no flow difference from the start to the finish. The water’s velocity is the same from head to tail.  We looked to Mother Nature’s concept of an Alluvial Fan, or Plain, to come up with a much better method of extracting gold.

Prospectors Choice Alluvial design takes advantage of a continuously slowing water current, and just like in nature, drops more gold in less time.

The Alluvial effect creates a continuously lowering water pressure zone, allowing gold of different sizes and weights to drop out of suspension at different intervals. This sluice box works by a constant capture system. We have focused on the entire length of the sluice box as being one big capture element.

Made for easy transport, set up, and clean up… and a long lifetime of use

The Explorer 23 River Sluice Box  trough is made from lightweight, rugged, premium-grade 5052 16-gauge (1/16’) aluminum. It has a high fatigue strength, excellent corrosion resistance, perfect for marine atmospheres. Both the riffle tray, and the raised 1/4″ expanded, are steel. Solid welds ensure a long life time of use.

How it works

Upon entering the alluvial sluice, the material instantly lands on a heavy duty assay matting, made of ribbed rubber matting.

The material then flows over our rod-style riffles, backed by black ribbed carpet.

This style of riffle allows for easy clearing of gravels, while still capturing even the smallest pieces of Gold.

The black background shows high-contrast material such as gold very well.

Hinged riffle design makes clean up quick and easy.

Compact size makes clean up into a pan, bucket or tub simple and easy.
