Replacement or a different HyFlex blade option
Use this pair to replace damaged Switch blades while retaining your serviceable HyFlex foot pockets and straps, or choose them when assembling a HyFlex system. TUSA’s angled blade and six ridges behind the vent are designed to manage water flow and reduce resistance through the kick.
These blades form part of the HyFlex system with TA0903 foot pockets and TA0919 attachment hardware. Check the fixings during assembly and before a trip. Rinse after diving and store the blades flat, away from heat or heavy items that could distort them.
