Proline 3 inch dredge for getting the gold.

Proline Mining set out to build a machine that addressed most of the problems associated with this dredge size.

The Proline 3" is built as a three inch dredge, Not a scaled down 4". This dredge is designed to be smaller and lighter than the 4" dredge without sacrificing strength or stability. To this day the HP 300 is the only pump on the market designed specifically for 3" dredges.

This is the smallest dredge equipped with the well known "sure flow" hose coupler system. The coupler is not glued to the hose, but actually spins onto the hose and then clamps to the Jet tube. This makes most surface rock jams a thing of the past. The Proline system isn't going to fall off from silicone failure in the middle of dredging.

Prolines single sluice design with the wave classifier has been PROVEN in gold recovery for its owners.
