This kit puts the four building blocks of a Tusa Hyflex Tri-Force fin in one order: the Hyflex System Tri-Force blade set, a spare foot pocket set of two, a Tusa Spring Strap, and the hardware kit that holds it all together. Whether you’re assembling a fin from parts or keeping spares on hand, everything you need is in one place.
The Tri-Force blade set and foot pockets share a color choice of Black, Gun Metal, Indigo, Khaki, or White, with foot pockets sized XS, S, M, or L/XL so you can match your existing setup or build a new one. The Tusa Spring Strap (TA-0918) is a separate stainless steel bungee strap, available in White or Black, that swaps in for a traditional buckle strap. Its five adjustment positions and molded rubber heel cup with an oversized finger loop make it easy to get on and off, even with gloves, and it’s built to fit most open-heel fins from TUSA, Cressi, Scubapro, Oceanic, and Aqua Lung.
Round it out with the Hyflex hardware kit: a 3mm Allen wrench, four O-rings, and four stainless steel screws sized for all TUSA HyFlex modular fin models. Keep it in your save-a-dive kit for a quick fix between dives, or use it to finish assembling the blade and foot pocket you just picked.
