John--- I remember. Unfortunately PESCO did not get credit they deserved. This is often the way "real-life" goes.

But when I was "following the drywashers" I learned not to kick down and detect the riffle tray tailings from a PESCO constant air.

What ever happened to the "poppet valve" that worked by pressure to change a constant air into a pseudo bellows?
I thought this adaption could have promise but it never caught on.

Anyone out there reading this thread, just jump in with any comments. A poppet valve may be what will make Wishbones land dredge workable?
