All Tsunami lures are tank tested to assure proper performance and strike triggering action. Precision weight transfer designs in most models assure improved, tumble free casting performance and a better balanced swimming action. Premium Mustad or VMC Cut Point hooks are attached to each molded-in stainless steel anchor or through wire with strong stainless steel split rings for sure hook sets. Black nickel hooks are used on all fresh water models. Sonic rattle attractors help get the attention of predators to zero in on each lure.
