Chinook diver have directional troll fishing sinkers, for both sides of the boat and at multiple depths, all at the same time. You can run multiple lines off you fishing boat.Chinook Divers are designed to work best with thin wire line and the super braided lines. Use a 2 to 1 foot ratio calculation for line out-vs-depth 100 feet of line out will get you 50 feet down. Faster/slower trolling speeds and shallow/deeper will change this calculation slightly. In shallow water, a larger fishing diver will run closer to the back of the boat. In deep water, a smaller fishing diver will run further back behind the boat. Depending on fishing conditions and trolling speeds, you can see a few accidental releases depending on speeds and conditions
