![]() The classifier develops a pulsing, or "jigging," action which prevents the dredged material from loading up under it. This dredge uses the highly acclaimed "wave classifier" which is proven to greatly enhance fine gold recovery by eliminating the problems associated with processing low grade sand. Our unique one piece jet/flare assembly not only reduces down time caused by rock jams, is extremely light, and outlasts conventional steel jets by four to five times! This dredge is equipped with our "sure-flow" coupler, which essentially, eliminates all surface rock jams. We highly recommend this engine/pump package for anyone who dredges to greater depths or at higher altitudes. This is the only pump in the industry designed specifically for the GX200 engine. The HP400 is a very efficient 3"x 2" pump with a high flow, "progressive bite" five vane impeller. The dredge can be equipped with either the Honda GX160 engine and HP350 pump or the Honda GX200 engine and HP400 pump for additional power. It's a sturdy bolt together design which allows the dredge to be disassembled into smaller components for ease of transport. The frame remains essentially the same as previous models. This model is equipped with pontoons that have increased stability over previous models, while remaining compact and lightweight. Small enough to slide into a pickup, light enough to be packed into remote areas, the 4" makes an excellent one man dredge. The light weight, portability and affordability of our 4" dredge makes it appealing to both the weekend prospector and the serious dredger alike. For full 2 diver support we recommend the 45HPJG with a 263 Gast compressor. T80 air compressor can be added to support up to two divers. The wave classifier and underlying riffles and rubber matting can be removed to allow quick clean up of the top of the sluice without lifting the main riffle tray. Precision cut and fabricated sluice and riffles allow the use of unbacked miners moss to make for easier clean up. Hungarian riffles are used for efficiency and miners moss is used throughout the sluice box. Material coming out of the flare and into the sluice box encounters a jigging action allowing the heavy values to concentrate under the classifier while all lighter material work out of the box. Another unique Proline design feature is the combined heavy duty rubber damper and wave classifying tray. The integrated power jet and cross linked polyethylene flare, allows material entering the flare to slow down and spread out. This coupler (shown) eliminates clog prone surfaces at the rear of the power jet and allows the suction hose to be removed with the flip of spring latches. Coupling the suction hose to the power jet is a Proline engineered and machined quick release “sure-flow coupler”. ![]() The high volume/pressure ratio is coupled into the power jet with a 2” high pressure hose. Powered by a Honda GX200 engine and Proline’s 400 GPM high volume pump, this dredge is uniquely tuned to provide maximum suction and water flow for recovery of fine gold. The PROLINE 4” JET FLARE dredge incorporates several innovative design changes to the more conventional dredges in its class.
