I have a 3" dredge for sale or trade. $1500 obo. Trade for? Old Keene yellow floats and frame and the box is designed for fine gold. I do have a small section of riffles for it, but have never used. Box has expanded over miners moss and 1/4" stainless mesh to overrun the larger rocks. 5 HP Briggs with T-80 compressor. I will include a regulator, but no reserve tank or air lines. Everything works great! All hoses are very useable, but are sunburned. Here's a few pics. Located in Denver.
