Constant weight bifins 820 mm length S glass fiber
Apnea bifins with very long blades for maximum propulsion for each kick. The length of the blade increases the leverage effect, finning is ample, while sparing energy. Less kicks for a same distance. S glass fiber provides a better resistance and improves durability. You can choose a branded closed-heel footpocket or a custom-made open-heel footpocket. This one frees the rotation of the ankle in all directions and thus increases the finning's amplitude and the efficiency thanks to a more precise foot positioning on the blade. Finally, it facilitates direction changes. It takes a little time to get used to it.
These fins were designed for deep diving, they will not be comfortable for surface movements. Depending on your weight, the stiffness you choose will allow you to descend to 35 m and beyond for the lightest and most trained divers.The 5% higher yield compared to E-glass will allow you to limit energy consumption a little more. To choose the right stiffness, use our selector 'which model for me ?'. Hardness gives more power but consumes more energy.
PRECAUTIONS FOR USE :
Your fibreglass or carbon blade can break :
- If the fin is stuck (the end of the fin is stuck, all the weight is on the blade and it cannot bend) => Do not push off with the blade on the bottom, the side of the pool or on the bottom of the water
- If you jump into the water with the blade parallel to the water.
