Introducing our new line of A.I. inspired composite fin blades (the A.I. stands for almost invisible). We've combined 30 years of composite design and manufacturing with our 50 years of spearfishing innovation to produce the best damn blade on the market. These blades provide a uniform stiffness at the foot and taper to a soft or medium flex at the blade's end to produce maximum thrust while minimizing leg fatigue. These blades look incredible. A proprietary resin delivery process combined with ultra fine fiber weave cloth allows for the brilliant translucent finish that make the graphics pop at certain angles and semi see-thru at others.
