Anyone Used The Quicksand Concentrator Or Familiar With It?

The science behind it seems credible, but the information about it on line is really limited. Size screening the feed and adjusting the water flow should theoretically give one the opportunity to tweak it somewhat?Any comments would be really appreciated.

few years back I almost bought one but while researching it on youtube I saw one of Doc's videos where he made a little fluid bed concentrator from a outlet box. I made one and used it a few times with black beach sands, it did work.
