[QUOTE="Mike Marsupial, post: 389731, member: 11868"] Hi Matt, Thanks for your post. I've looked at Knudsen bowls and they look pretty good. Apparently there's a bit of an improvement whereby water is injected back through the riffles to lift the lighter stuff back out again. One British site claimed 99% efficiency. You can buy big ones from China for 5 or 6 grand, but they are very big!!! Just looking at inline pressure jigs now. Thanks for the heads-up. [/QUOTE]
