Nomad incorporated their patented Autotune System into this bait which allows for the perfect balance and action even under truly fast troll speeds. It has a seductive S-shape swimming action and tail kick, ready to troll 5-10 knots and work an area or 10-15+ knots to cover ground. Each lure is built tough to withstand strikes of tuna, wahoo, and more as it features a full Metal Matrix Internal plate with Diamond Armour Construction. Additional pin supports, vertical internal reinforcement, and beefed-up welding give it the Heavy-Duty status. Before production begins, each lure blank is pressure tested under extreme loads for several minutes, giving the angler full confidence in their gear.
