The Elec-Tra-Mate Dredge Master 400 was created to eliminate the unnatural jerking action of rods by heavy dredges.Manufactured from aircraft aluminium for strength and lightness, it is then anodized black and gold for protection and lasting beauty, making the Dredge Master 400 a work of art.The Elec-Tra-Mate Dredge Master 4000 features a solid aluminium shaft to handle the extraordinary amounts of weight and features a swivel roller tip with a 2 ?” roller that spins effortlessly on two stainless steel bearings. The swivel head has a large stainless steel bearing for rotation and a thrust bearing with 1,910 lbs. of load capacity for silky smooth operation. Additionally, the roller is machined for 400 lb. monofilament line which is being used to pull these dredges.Because of the strength of this product, dredges and other heavy lures may also be pulled to the side rather than directly off the transom, giving the lures a wider spread.The Elec-Tra-Mate Dredge Master 400 is available in two sizes. The DM-4 is designed to fit into a 80 lb. class curved rod butt while the DM-6 is designed to fit into a 130 lb. class curved rod butt.The Dredge Master 400 is manufactured entirely in Elec-Tra-Mate’s North Carolina factory, and comes with a one-year warranty against defects in material and workmanship.
