Experience powerful propulsion, precise control and efficient finning with the TUSA HyFlex Tri-Force Fins. Designed for recreational and experienced scuba divers, the Tri-Force combines a compact, wide blade with TUSA’s advanced vented design to produce strong thrust without unnecessary resistance.
The distinctive short and wide Tri-Force blade responds quickly from the first kick, making these fins an excellent choice when you need acceleration, manoeuvrability and control underwater. Three strategically shaped vent holes channel water through the blade, helping reduce turbulence while improving water flow and propulsion.
TUSA’s Vortex Generator technology further manages water flow around the blade to reduce resistance and improve efficiency. The result is a responsive fin that converts your kicking effort into useful forward movement rather than wasted energy.
As part of the TUSA HyFlex System, the blade, foot pocket and strap are modular components. This makes the fins convenient for travel and allows compatible HyFlex components to be separated or changed when required.
Why Choose the TUSA HyFlex Tri-Force?
- Powerful Propulsion – the wide, short blade produces strong thrust from the beginning of each kick.
- Three-Vent Blade Design – strategically positioned vents improve water flow and help reduce turbulence and resistance.
- Vortex Generator Technology – further controls water movement around the blade for smoother, more efficient finning.
- Excellent Manoeuvrability – responsive blade design provides precise control when turning, positioning or navigating tighter dive environments.
- Reduced Wasted Energy – efficient water flow helps convert your kicking effort into useful propulsion.
- Comfortable Open-Heel Foot Pocket – designed for a secure and comfortable fit with dive boots.
- TUSA HyFlex Modular System – separate blade, foot pocket and strap components provide additional flexibility for travel, replacement and customisation.
- Compact Tech-Style Blade – delivers strong performance without requiring an excessively long blade.
- Versatile Performance – suitable for recreational scuba diving, advanced diving and divers wanting a powerful, responsive fin.
Tri-Force Blade Technology
Rather than relying simply on blade length to generate power, TUSA uses a short, broad blade with three specialised vent holes. Water is directed through the vents during the kick cycle, helping minimise unwanted turbulence and resistance while accelerating water through and around the blade.
Combined with the Vortex Generator design, the Tri-Force provides the combination many divers look for in a high-performance fin: strong acceleration, efficient propulsion and precise underwater control.
TUSA HyFlex System
The modular TUSA HyFlex System allows the blade and foot pocket to be separated, making the fins easier to pack and giving divers greater flexibility when configuring compatible HyFlex components.
For divers looking for a modern open-heel scuba fin that combines power, manoeuvrability and efficient water flow, the TUSA HyFlex Tri-Force Fins are an impressive choice.
