Scubapro Twin Jet Max fins-with FREE Boots & Gloves Discover the power of the Twin Jet Max split fin by SCUBAPRO. *** Please add boots & gloves sizes into the notes section when ordering. *** *** 3mm or 5mm glove will be sent depending on stock Levels *** The Twin Jet Max Fin features a patented split-hydrofoil shape to deliver optimum power with minimum effort, plus dual-compound construction, which enables SCUBAPRO to fine-tune performance & optimize maneuverability & diver comfort. The new spring strap means that you can easily & quickly slip on your fins. No struggling with adjustments or getting a twisted strap over your boots. The spring strap system simply rolls onto your heel & keeps the fin snugly, yet comfortably, on your foot. Its added durability & sturdiness make your Twin Jet Max fins fit for a lifetime. There are three primary variables to consider when selecting a fin: power, efficiency & fit. The more water a fin moves, the greater its kicking power. Furthermore, fins that transfer a greater percentage of a diver's kicking effort into forward motion are considered to be more efficient. TWIN JET MAX FINS do just that! Quick release easy adjust buckles. Semi rigid side rails for blade stability throughout kick. Bio-engineered soft foot pocket for seemless energy transfer. Vented area for hydrodynamic superior flow during upstroke. Bi-material blade for ideal blending of flex & performance. Proven patented split-fin technology. All SCUBAPRO split fins employ a truly remarkable propulsion technology that uses an unconventional hydrofoil shape to produce forward motion with considerably less effort than any other conventional blade. This secret lies in the patented design, which allows water to flow between & around each of the twin blades, which flex independently to produce propulsion in much the same manner as a propeller. Blades are also angled to provide symmetrical power on both up & down strokes to achieve seamless propulsion. TWIN JET MAX ADJUSTABLE FINS Patented split-fin propeller technology has been proven to deliver more forward motion with considerably less effort than traditional blades. Dual-compound construction blends the best characteristics of two different yet compatible compounds to achieve the highest level of performance. Drag-reducing vents substantially decrease resistance on both up & down strokes. Extended sole plate acts like a lever to enhance power stroke. Soft, vented foot pocket is bio-engineered for optimum fit & comfort while seamlessly transferring energy from the diver to the fin. Quick-connect swivel buckles with quick-adjust straps facilitate adjustment & use. Available in Red, Yellow & Blue
