A new addition to SCUBAPRO's S-Tek line of technical diving equipment, the S-Tek Fin is a purpose-built, next-gen technical diving fin providing maximum power when you need it. Constructed of durable Monprene and designed with an ultra-streamlined profile, the S-Tek Fin's 30º pre-angled blade requires less deflection to achieve the desired angle of attack for an efficient kick. This allows for a stiffer blade without increasing drag, thereby reducing leg cramps and ankle strain while delivering unbeatable maneuverability and alternate kick performance. The S-Tek Fin's two-piece design, with blade and foot pocket molded separately, allows you to use the same foot pockets from the Seawing Supernova fin with just the S-Tek blade. Simply disassemble the Supernova's Socket-Lock Connecting system, switch out the Supernova blade for the S-Tek blade, reassemble, and you're ready to hit the water.
