TUSA SF-0104 Hyflex Switch Fins

Winner of the Scubalab Testers Choice Award 2017, the TUSA Hyflex Switch Fins are perfect for divers who like a responsive and crisp fin. Powered by PuRiMax, these fins are comprised of a polyurethane blade system. This high quality material is ultra responsive to movement to give a smooth and snappy experience. If you like to make quick movements on a whim then these fins will keep up with you perfectly.

The foot pocket on the fins is designed to enhance comfort while also making sure that the maximum amount of kick power is transferred through the blade to give ultimate performance. As well as this the fin comes with an angled blade design that is engineered to be as efficient as possible. It many fins when you kick a lot of the power is lost due to poor design, not with the Hyflex Switch fins however.

With efficiency and performance in mind, the fins also come with the TUSA Vortex Generator. This is made up of six ridges positioned behind the blade vent to reduce resistance and enhance performance. This reduced resistance means that kicking will be smoother and provide greater power.

To make sure that the fins are as comfortable and practical as possible they come with a bungee strap as standard. This is designed to make putting the fin on and taking it off as easy as possible and comes with a quick adjustment system in five key areas to ensure that this is the case.

Key Benefits

  • Super Responsive -The high quality polyurethane material that the fins are made up of is more responsive than standard rubber or plastic fins, allowing you to make fast movements on a whim with the fins keeping up.
  • Great Quality - Powered by PuRiMax, the high quality polyurethane material is highly durable and will take on the most rugged of dives.
  • Designed for Comfort A comfort foot pocket on the fins is designed to make them as comfortable as possible when on, even when you’re kicking ferociously.
  • Bungee Strap - The fins come with a bungee strap as standard which is designed to make putting the fins on and taking them off as easy as possible.
  • Efficient - The TUSA Vortex Generator is a clever six ridge system that works to make sure that all the effort you’re putting in to kicking is being transferred to a powerful kick on the fin.
