263-Gast compressor with storage tank and pressure gauge that will supply air to 2 divers (brand new condition).

Twin 9-HP motors in brand new condition.

Non-slip decking to allow ease of movement and gear-storage on the platform.

6-inch Proline dredge platform with an extra set of pontoons on the front end (dredge is in brand new condition).

Here are some live videos which demonstrate this dredge:įine gold recovery under double-screen classification Machining to allow these adjustments is by far the best ever done. This allows flows to be modified on all three levels according to the needs of different locations. The two classification screens are adjustable in height. This system and technology is basically priceless, since it only exists through custom-made fabrication by only a few people. From years of extensive testing, we have found that it does not get any better than this for processing volume amounts of material through a suction dredge.

Material which drops through the 1/8 th inch screen (all of the gold that is not trapped in the high-grade section at the head of the box) is then washed across a combination of turned-up expanded metal over top of ribbed rubber matting. Under the 3/8 th in screen is an additional 1/8 th inch screen which allows another cut of the oversized material to be discarded into tailings. After the high-grader up front (which recovers an important portion of your daily gold), there is initially a 3/8-inch classification screen which allows all the larger-sized material to be immediately discarded as tailings. The most valuable part of this dredge is the double classification system. Very low hours on the twin 9-HP Honda motors with authentic Proline pumps (best in the world). The 263-Gast compressor allows for two divers. Two additional floatation modules have been added, along with decking so one or two people can get onto the dredge even when it is operating.

This is a huge time saver because it allows you to leave the super-fine gold recovery sections alone (without any worry of gold loss from them) until they are worth the time to clean-up.

This 6-incher is a step up from my own Pro-Mack 5-incher (which is the 3 rd generation of double screen classification) largely because we have added a high-grade gold recovery section at the head of the box which recovers all the larger sized gold and has preliminary fine gold recovery section that can be cleaned up every day with minimal effort.
