Thanks Steve,
I've heard everything from 4 to 24 hours run time, but I would imagine the variety of batteries being used are the culprit. I've also heard Keene has changed pumps, opting to increase the flow to around 650 each, but I agree that better flow could be attained using it as a sluice. I've been using the A52 and have been impressed with the rate of feed and fine gold catch in stock form (zero flour gold found in my tailings so far...). I like that there's a port to add a gasoline pump as well. The cam lock legs are a nice touch. I contacted Keene regarding selling just the rotating leg kit, but their response was that it would be cost prohibitive at this time (around $150)...
