The Inviz Wire Pro spinnerbait is built around a frame constructed from .040", heat-treated, brown color super wire that is stronger than traditional stainless wireand is much less visible to the fish. The "wobble" head design eliminates torque on the wire while producing added vibration. This design creates very straight tracking even at higher retrieve speeds and prevents fish from gaining any leverage to throw the bait. The sliding sleeve feature allows you to fully customize your spinnerbait by changing out head size or head/skirt color as well as blade size/color in seconds. Smartmouth Plus heads and individual grommeted skirts can be purchased separably to change out and customise your head/skirt color. Sampo ball bearing swivels, premium silicone skirts, .040 low viz brown wire, and 3X strong Mustad ultra point hook.
