There is a sump in the back that comes with two different size screens. The sump can be rigged as a positive pressure flotation fluid bed or just use it for collection of the fines and heavies directly to a bucket. The table level and slope is adjustable independant from the base.

This is professionally manufactured not home brew and should work really good. It needs some scrubbing, tuning and the carpet or moss of your choice but no overhaul. I bought it to use as trading material but the trade fell through, Now it has to go.

Asking $700 OBO
