Free diving bifins 820 mm length E 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. The perfect fins to taste the composites. 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 long bifins are suitable for the practice of dynamic apnea in large pool. Glass fiber will allow you a strong progression compared to plastic fins. For a practice in a small pool, they will be reserved for experienced freedivers with a good technique of turn and relaunch. For stiffness, in addition to your size, it is essential to know what technique you will use to cover the greatest distance in apnea. If you practice the slow option, few movements with great amplitude, you should prefer flexibility. If you rely on your ability to move quickly in apnea, higher frequency and reduced amplitude, you will have to opt for a higher hardness. To choose well, use our help: 'which model and which stiffness for me?'.
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.
