We use outriggers for a numbers of things on Lake Ontario. First we troll for Trout and Salmon, generally 2.5 mph. We can use the outriggers to run toplines in the spring when the water is cold and the fish are near the surface and again in the fall as the salmon are congrgating around the rivermouths in shallow water to run toplines. Also, during the summer months, we are generally fishing 50-150' down temperature dependent and we have a number of methods of getting extra lines out in addition to typical downriggers. Namely dipsey divers, leadcore line, copper line, drop weights etc. The outriggers can allow you to use these methods and get them away from your downriggers a bit further.
