I've used the standard leaf blower available at Home Depot, Walmart, Lowes with the plastic blower nozzle removed. Take along a foam pad (like a gardening knee pad) for blower to rest on. Seen rocks gouge their way through plastic fuel tanks if it sits on gravel while running. I also have a high end vacuum/ blower that I can hook up in case the other taps out. When you set it up put the hopper end up wind so dust blows over the drywasher and not all over you. I clamp a piece of plywood to the front legs to keep the material from loading up under the drywasher and stopping the vibrating lower part. I learned from an old timer that once you're done running your material shut it off or remove the blower hose. A stream sluice can be kept in the current after you're done, a drywasher will blow out your concentrates if you let it run too long. Also, don't run material that is too damp or at least run that material thru a second time. Run a metal detector over your debris pile when done running. Take along water to pan your concentrates or pan them at home. Good luck!
