U-Charters Slide Diver w/Tension Spring - U-Charters Slide Divers are a new take on the standard diver design. These fully adjustable trolling sinkers rig with the mainline running through the body of the disc. That means when a fish strikes, the diver runs freely along the line with little to no resistance. Leader length is no longer restricted as the line can be locked in at any point allowing the angler to stretch the offering well behind the diver, which instantly releases at the lightest bite from a fish. As soon as the rod moves, remove it from the rod holder and reel in. Fully adjustable trolling sinkers; Great for all species of freshwater gamefish, including walleye, lakers, steelhead, and salmon; Contains one diver, full rigging instructions, and rigging accessories including a bead, four pieces of vinyl tubing, and a barrel swivel.;
