I had a Proline 2" high banker dredge combo and loved it. As a high banker it was great, found a lot of gold, but the streams we were working here in Northern Cal. were too large for a non floating dredge so I ended up selling it. They do make the floats for it, but then it makes it almost the size of a 4", so why not use a 4" and that's what I did. I bought a used Proline 4" and ran it for 2 years with good results, so I figured bigger is better and last year I bought a brand new Keen 6". Of course work messed me up last year so I only got to take it out once for 2 days, but I did find almost 1/8 oz of fines and that was just in over burden. Never reached the bedrock. This year I'm planing on a couple of week long trips, so hopefully I can see what it can do. I think the build quality of the Prolines are better than the Keens, but The Keens are better for fine gold recovery. Hope this helps.
