Keene 2.5" gold dredges are very popular for those wanting a portable suction dredge at a lower price than larger gold dredges. These gold dredges are perfect for day trips or exploration where mobility is of prime importance. Remember that 2.5" dredges do not move very much volume and so are best used on or near bedrock where gold values are most concentrated. A 2.5" dredge is the smallest that can be outfitted with an air compressor for those wanting to work underwater. The Keene 2.5" dredge is exceptionally powerful with a motor and pump combination capable of running a 3" gold dredge. This means you can throttle down for better fuel efficiency or throttle up for extra suction power. Keene 2.5" dredges feature their oversize powerjet with quick coupling system. This dramatically reduces clogging and in the rare event of a clog, allows for quick and easy access to the hose. Compare to the competition and see why a Keene 2.5" suction dredge is your best value in a portable gold dredge.

Keene 2.5" Suction Gold Dredge
This 2.5" dredge is equipped with all the latest innovations in dredge design similar to the larger dredges. This is an extremely versatile dredge that can be used as a standard floating dredge with an optional air compressor for deeper dredging, or bank mounted for shallow water applications. A 2.5" dredge is the smallest that can be outfitted with an air compressor (shown in picture to right) for those wanting to work underwater.

Our 2.5" dredges all now come standard with 20 feet of suction hose so you can reach farther and move the dredge less often.



Features for the 2.5" Dredges
bulletThe flotation is extremely light and compact and can be assembled or dismantled in a matter of a minutes. The floats have built in storage indentures providing a place for your tools, mask, rock pick etc. The floats have stringers, or "runner bottoms" for fast water and rock laden bottoms.
bulletThe dredge is equipped with Keene's powerful new PHP160 160 gpm pump with oversized pressure hose making it a more powerful dredge than ever before. Experience greater suction power with either the power jet or optional suction nozzle model.
bulletThe 12" X 40" sluice box has rolled top edges, tapered sluice design, longer classifier screen and improved riffle design for superior recovery. Equipped with ribbed black rubber matting, for quick identification of values, under a longer classifier screen. This 2.5 inch sluice box surpasses all previous designs for both fine gold recovery and ease of use.
bulletThe Marlex Jet flare is built with a longer straight section and flare making it possible to use a shorter power jet to reduce weight. The jet flare design also improves fine gold recovery and increases suction power. The jet flare also makes the dredge easier to set up in shallow water conditions. The sluice box can also be set independently on a flat area next to the water.
bulletThe sluice box design is built to accommodate a power sluice hopper.

Keene Oversize Powerjet with Quick Coupler System
Keene Oversize Power Jet with Quick Coupler System
We have taken the standard Power Jet and created a more efficient, easy to use and overall superior jet! The new design involves a slight enlargement of the jet tube, making it a bit larger than the interior of the suction hose. The result of this modification is a smooth, seamless flow from hose to jet. Rock jams and other obstructions are virtually eliminating downtime. The quick coupling features two side mounted snap levers for quick and easy joining.
AMDS has Keene suction dredges for gold and other valuable minerals. The suction dredge is the best method for the small miner to recover gold from underwater deposits. Gold dredging is a relatively inexpensive method of mining for small one or two man mining operations, and can provide reasonable returns for the hard-working miner. Keene Engineering is the oldest and largest manufacturer of portable suction gold dredging equipment. Note: the State of Alaska requires a permit for all suction dredges operating in the State of Alaska. See our Suction Dredging Regulations page for details.
