At Bear Bottom Mining we have been building sluice boxes since 1979. We have gone from a narrow wood box for Grizzly Sluice 1...to a wider hinged riffle system in Grizzly II...to a wider, light weight, heavy duty aluminum sluice box made from .090 thickness aluminum, which no other box on the market is made of, like our Grizzly Sluice III. We have the only box on the market with it's own water regulation baffle built right into the box, which makes it goof proof !!

Our web site is www.bearbottommining.com  We have a video presentation under product info and this box was originally designed to save .999 fine flour gold that every one else's equipment would not save. But the added bonus is not only does it save flour gold, but all of the coarse gold as well as precious stones, which really add up to making your camping or prospecting trips profitable. 
It is the most accurate sluice box for doing cross sections up a river 
that anyone has had the pleasure to use. We offer a back-packer model that allows the prospector to not only be able to pack in a sluice box, but a pick 
shovel combo, a gold pan, a collapsible water bucket, a thermal mining 
bag that not only carries his lunch, but carries his snuffer bottle, black 
sand container, black sand magnet, small crevice tool, and mining 
solution " bio degradable detergent ".

The best part of all is the back-packer comes with detachable back pack straps, so they don't get all wet and muddy while mining. We are also on you tube under "sluice boxes" although the clarity on you tube has a lot to be desired. Once again, thanks for your e-mail, we are excited to have the opportunity of working with you.
