Holographic Trout Killer Trolling Lure Black Pearl with the Electronic EChip Attractor.  The holographic series of Trout Killers is an upgrade to the standard model.  The difference is that the holographic model has reflective fish scale holographic tape on the top.  It reflects more and provides a more lifelike look to the lure.  All 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. Instructions are on the back of each packaging card.
