Product Information

The Tusa HyFlex System Tri-Force Blade Set (item TA1802) is the interchangeable blade-only component of the TUSA HyFlex System, built around a wide, short tech-style blade with three uniquely shaped vent holes and Vortex Generator technology for powerful, efficient propulsion. It is sold as a blade set only, so foot pockets and hardware are not included, and it is offered in Black, Gun Metal, Indigo, Khaki and White.

Who it is for

TUSA rates the Tri-Force blade for all dive levels, so it suits recreational divers, instructors and tech-minded divers who already own or plan to build a HyFlex System fin and want to swap blades rather than buy a complete fin. The lightweight composition makes it easy to transport, which is useful for travel divers packing a bag, and the energy-saving design is aimed at reducing leg fatigue over long dives. It is also the right choice when you want a second color or a spare blade for an existing HyFlex setup.

Key details

  • Blade style: wide, short tech-style blade for responsive, powerful kicks.
  • Vents: three vent holes, each uniquely shaped and positioned to accelerate water flow and cut resistance.
  • Vortex Generator technology: suppresses resistance around the blade for smoother, more efficient kicking.
  • Item number: TA1802, with SKUs TA-1802-BK, GM, ID, KH and W by color.

Compatibility and sizing

The blades are part of TUSA's interchangeable HyFlex System and pair with compatible HyFlex foot pockets and hardware. TUSA also lists compatibility with the TA0918 spring strap, which offers five size adjustments. Because this listing is the blade set only, you will need compatible HyFlex System foot pockets and hardware.

Frequently Asked Questions

Does the TUSA HyFlex Tri-Force Blade Set include foot pockets?

No. This is the blade set only, the interchangeable blade component of the TUSA HyFlex System. Foot pockets, straps and mounting hardware are not included and must be sourced separately from compatible HyFlex System parts. If you already own a HyFlex fin, these blades let you change blade style or color without replacing the whole fin. Contact us if you need help confirming which parts you need.

What makes the Tri-Force blade different from a standard fin blade?

The Tri-Force uses a wide, short tech-style blade with three vent holes, each uniquely shaped and positioned to accelerate water flow and reduce resistance. TUSA pairs this with Vortex Generator technology, which suppresses resistance around the blade for smoother, more efficient kicking. The result is responsive, powerful propulsion with energy-saving efficiency intended to reduce fatigue.

Which strap works with the HyFlex Tri-Force blades?

TUSA lists the Tri-Force blade as compatible with the new TA0918 spring strap, which offers five size adjustments. TUSA lists the Tri-Force blade as compatible with the TA0918 spring strap, which offers five size adjustments. Call 888-701-4017 if you want to confirm the right strap and foot pocket combination for your setup.

What colors are available for the TA1802 Tri-Force blade set?

The Tri-Force blade set is offered in five colors: Black (TA-1802-BK), Gun Metal (TA-1802-GM), Indigo (TA-1802-ID), Khaki (TA-1802-KH) and White (TA-1802-W). Because the HyFlex System is interchangeable, you can keep one set of foot pockets and swap blade colors, which also makes it easy to identify your fins on a crowded dive boat.
