Trout Killer Trolling Lure 2 Black Pearl with the Electronic EChip Attractor.  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 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.  Instructions are on the back of each packaging card.
