Target shooting bifins 640 mm length S glass fiber
Short target shooting bifins. This short length makes them very maneuverable and allows a faster activation. For a hardness index equal to that of a longer fin, they will in fact be stiffer. These fins are therefore only available in 3 stiffnesses. The S fiberglass will give you a return of energy 4 to 5% higher than the E glass but especially a fatigue resistance of 10 to 15% higher. 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.
The 640 SERIES will be perfect for biathlon events. Their fast activation allows you to increase your speed over a short distance. Easy to handle, they enable quick direction change directions and turn around. Due to their smaller size, these fins are only available in 3 stiffnesses. For the same hardness grade, the 640 fin is stiffer than a longer fin. 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.
