The Magnum Double Flash, from Angler's Market, is built on their internal tube system that all but eliminates line twist commonly associated with the technique. The dual willow blades, front size 6 and back size 4, create a great deal of vibration and flash that draws fish in and pique's their interest in the trailed lure. Attaching this trolling device is easy, it slides right onto the main line above a swivel joining the leader line and main line. We offer the Angler's Market Magnum Double Flash Troll in several color options certain to meet your Kokanee fishing needs.
