With the addition of a keel sinker 4 to 6 feet up the line from the spoon, shallow to medium depths can be trolled effectively. Sinker weights, depending upon the depth desired, usually run from 1 to 8 ounces with main line testing from 12 to 30 pounds. As in flatlining, let out 50 to 200 feet of line behind your moving boat and begin the troll. The Dipsy Diver is particularly unique diving sinker as the lead weight in its base plate can be shifted in degrees to produce starboard, port or behind the boat running. With the Dipsy you now can troll off to either side of the boat without interfering with flatlines or downrigger lines and cover an extremely wide swath of water.
Divers also act as fish attractors due to their color and shape.
With a downrigger you will be able to work all depths and will have the added advantage of no weights between you and the fish once hooked. Dodgers can be used as attractors in conjunction with a spoon behind a downrigger with good results. Allow 12 to 18 inches of leader between spoon and dodger. Shorter leaders produce more frantic and faster spoon action while longer one result in slower action. Flashers are yet another kind of attractor that can be used with a spoon behind a downrigger.
