Purpose-Built Power for Technical Divers
The SCUBAPRO S-Tek Blade is a next-generation technical diving fin blade designed for divers who demand maximum control, efficiency, and power underwater.
To simplify sizing, SCUBAPRO offers the S-Tek Blade in two blade sizes:
Midi Blade
- Compatible with Supernova Foot Pockets: XS, S, and M
- Ideal for divers using smaller foot pockets and seeking a balanced combination of maneuverability and power
Maxi Blade
- Compatible with Supernova Foot Pockets: L and XL
- Designed for larger foot pockets and divers looking for maximum thrust and propulsion
Built from durable Monprene® and engineered specifically for technical diving, the S-Tek Blade delivers exceptional performance during frog kicks, helicopter turns, back kicks, and other precision propulsion techniques that technical divers rely on.
Compatible with the SCUBAPRO Seawing Supernova Foot Pocket, the S-Tek Blade allows divers to customize their fin setup without purchasing an entirely new fin system.
Why We Love It
Designed Specifically for Technical Diving
Unlike recreational fins, the S-Tek Blade was engineered around the propulsion techniques used by technical and advanced divers.
Excellent Frog Kick Performance
The blade's rigidity and hydrodynamic design provide outstanding control during frog kicks and precision maneuvering.
Customizable Buoyancy
The removable stainless-steel weight system allows divers to fine-tune buoyancy characteristics based on personal preference and exposure protection.
Travel-Friendly Modular Design
The two-piece system packs smaller than many traditional technical fins.
Compatible with Supernova Foot Pockets
Divers already using the Seawing Supernova can swap blades without purchasing new foot pockets.
