sweet I actually didn't know that. I've been thinking of combining the bazooka with a drop riffle sluice. set it up kinda like the calsluice 2b. the bazooka would be the first part the screen would act like normal on the bazooka buteverything thar was pushed up would have another chance to get into the second half cause of a punch plate. ontop that anything small enough would fall down in and hit the drop riffle section. the fluid bed (if) anything got out of there would already be classified and would run over the drop riffle section just to kinda double up as a safety net.
but still on the drawing board. but all the times I've used my bazooka I've never been let down
so I may not even build this double decker sluice
