The longer term the operation, the more gold will be lost over time. If all you have is fine, flaky gold losses may be prohibitive. These are great unit for hit and run operations where you have coarse gold. If you are getting into gold, check the riffles to make sure they are clearing properly, and then slow up on cramming material through the unit. If you hog material, you will bury the riffle, and lose more gold. The riffle is small, and must be open to capture gold. Recovery issues with a subsurface are simple. It burns the amount of gas a 2.5" dredge would, saving more costs and weight. Thye entire unit weighs and costs about the same as a 2.5" surface dredge. This shortened the overall length and eliminated a clog point. ![]() Second, since I used a suction nozzle, I cut the tube opening into the box back far enough to insert the 4" hose into the tube and clamped it down. An alternative would be to use a 4" power jet mounted directly to the tube, which is how Keene normally did it. First, I opted for a suction nozzle design as I wanted to allow the gold to settle before it gets to the box and to reduce the chance of the riffles being "blown out" should the prime be lost in the main suction hose. ![]() NOTE: Frame is not included in this price because you will need to build your own.
