Jan 07, 2009· I think your title-"Building the Ultimate Dry Washer, A Dry Washer that equals a dredge in recovery rates" is somewhat misleading.

Feb 19, 2013· Dryblowing is a sure way to recover gold and am convinced the bellows type retains gold down to mustard if it is set up correctly and the dirt is dry, I mean dry, not slightly damp.

The design on a water sluice box is that the gold is retained downstream of the riffle. On a dry washer, the gold is designed to be held on the upstream side of the riffle.
