very good advice...panning is always more effective and efficient with well classified material! I do 12/20/50 myself.<img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=967646"/> Here is a pic after I cleared most of the rocks off and pulled the super mini out of the river. I had shoveled two quick giant scoops into it that had rocks up to fist sized. Notice the flake on the skid plate. No need to classify before. I classify it through a 12 and 20 stacked afterward. Makes for easy panning.
