These high performance fishing equipment, Chinook Diver - directional troll fishing sinkers, allow you to effectively cover a broad area, both side to side 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. A counter reel is very helpful in calculating depth. We use a 2 to 1 foot ratio calculation for line out-vs-depth 100 feed 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.
Generally, we don't use a "snubber". Depending on fishing conditions and trolling speeds, you can see a few accidental releases at accelerated troll fishing speeds or in rough water. We use 8 1/2 ft. or 9 ft. soft action poles with the divers. These give us the "snubber" type action to control accidental releases without adding more friction underwater.
