C4 Tank 25 Freediving Blades

C4 Tank 25 Freediving Blades are ideal for spearfishing and collecting, in particular chasing Crayfish and Abalone in the shallows as the reduced size of the blades allow for less movement caused by swell and waves. However, these are still fantastic fins that we would recommend to divers who are diving down to 30m Max. 

Tank Blades are made of 100% T300 TW carbon and they are inserted in the foot pocket all the way to the heel for an excellent transmission of energy through the blade to the tips of the fins. These blades are specifically symmetrical therefore increasing mechanical and dynamic efficiency. This solution reduces energy dispersion and torque forces which are typical of asymmetric geometries.

These blades are designed to suit the C4 300 and 400 footpockets, connected to the pocket by a mechanical insert that is blocked by two special screws that cannot be easily unscrewed, providing a safe and efficient connection.
