TUSA HyFlex Switch Fins: Product Overview
The TUSA HyFlex Switch is built around a solid polyurethane blade and TUSA's modular HyFlex system. The blade can be separated from the foot pocket, reducing the length of the fins when packed. This is particularly useful for divers traveling with a full set of scuba equipment who want to make better use of their luggage space.
The blade uses TUSA's PuRiMaX polyurethane material, which the manufacturer describes as providing a quick, snappy response to fin movement. A Vortex Generator is designed to reduce water resistance through the fin stroke, while the multi-compound foot pocket helps transfer movement from the foot to the blade.
The HyFlex Switch also comes standard with TUSA's Universal Bungee Strap (TA0902). Combined with its angled blade design and detachable construction, it is a distinctive option for divers who want a more compact fin system without moving to a conventional split fin.
What Makes the HyFlex Switch Different?
PuRiMaX Polyurethane Blade
TUSA's polyurethane blade material is designed to respond quickly to changes in kicking movement. For divers, that means a blade designed around a direct, responsive feel rather than simply being a compact travel fin.
Detachable HyFlex System
The blade separates from the foot pocket, making the fins shorter and easier to pack. It is a useful design detail for dive travel, particularly when luggage space is limited.
Vortex Generator
TUSA's Vortex Generator is designed to reduce water resistance during the fin stroke. It gives the blade a different profile from a conventional smooth-blade design.
Angled Blade Design
TUSA's Angled Blade Design (A.B.D.) positions the blade at an angle to the foot pocket. The design is intended to lengthen the stroke of the kick cycle.

Frequently Asked Questions
What makes the TUSA HyFlex Switch different from regular scuba fins?
The HyFlex Switch uses a detachable blade-and-foot-pocket system, allowing the fins to be separated for more compact packing. It also uses a PuRiMaX polyurethane blade and TUSA's Vortex Generator.
Are the TUSA HyFlex Switch fins split fins?
No. The HyFlex Switch has a solid polyurethane blade. The TUSA HyFlex Zoom is the split-fin alternative, with a six-gill blade design.
Can the blade be detached from the foot pocket?
Yes. The TUSA HyFlex system allows the blade to be separated from the foot pocket, helping reduce the length of the fins when packing them for travel.
What type of diver are these fins designed for?
TUSA classifies the HyFlex Switch as an advanced diving fin. Its polyurethane blade, Vortex Generator and modular construction make it an option for divers who want a performance-focused fin with a more compact packing design.
Do the TUSA HyFlex Switch fins come with bungee straps?
Yes. TUSA lists the Universal Bungee Strap (TA0902) as standard equipment with the HyFlex Switch.
Can I wear the HyFlex Switch with dive boots?
The open-heel foot pocket is designed for use with suitable dive boots. Boot thickness and sole construction affect fit, so check the sizing guide and try the fins with the boots you plan to dive in.
Are the HyFlex Switch fins lightweight for travel?
Their detachable design makes them more compact to pack, but they are not the lightest fins available. TUSA catalogue figures list pair weights of approximately 1.76–1.97 kg depending on size.
What is the difference between the HyFlex Switch and HyFlex Zoom?
The Switch uses a solid PuRiMaX polyurethane blade, while the Zoom has a six-gill split blade. Both use the HyFlex modular system, so the main decision is which blade design you prefer.
