The Pro-Troll Trout Killers are deadly for trout. When trolled between 1.5 and 2 mph they have a wild darting action that attracts trout. The size 1 lure is 1.5 inches long and the size 2 is 2 inches long. Each lure is equipped with raised eyes and a size 4 hook and a red flicker blade. Each lure is equipped with the Pro-Troll electronic EChip which discharges tiny electric nerve pulses which exactly duplicate the nerve discharge of a baitfish. The size 2 Trout Killers are equipped with a third rigging hole for extra slow trolling. When the leader is threaded through the third hole the lure rides at a much steeper angle thereby allowing good action at very slow speeds.
