C4 Falcon MST

C4 Falcon MST

The carbon fiber blades that have changed forever the way to do freediving.


MATERIAL: 100% carbon fiber T700 SUPERFORCE

BLADE DIMENSION: 790 x 190 mm

BLADE HARDNESS: 25 soft – 30 medium – 40 hard

WATER RAILS: Constant h10mm



A standard stiffness (Tensil Modulus) combined with a 40% higher resistance (compared to the standard) makes T700 High Tensil carbon fiber particularly suitable for more reliable and durable fins. This new line of fins by C4 is manufactured with this T700 composite material. This line of new fins are manufactured with a standard elastic modulus (ability and speed of the material to return to its original position after having been bent) and high resistance (to breakage) carbon fiber. In addition, we have introduced the new large square fabric texture whose fibers are 5 times bigger to improve the performance. The wide bands of the weaving of the T700, compared to traditional carbon fiber cloth, reduce the number of total weaves. Weaves create friction and bend the extremely thin wires of the fiber. Friction and bends, generate negative effects on the performance of the blade. Reducing this effect, by using T700, results in a higher resistance and much better elastic return of the blades, generating more efficiency (more push and less fatigue) when diving.

D.P.C. Double Parabolic Curve

The blade works best when it bends completely? From heel to toe !! This is possible thanks to the double parabolic curve of blades, from heel to toe. A neutral intermediate bottom and two progressive declining curves. Thus it fully exploits the shovel and its elasticity.


Blades concave shape pushes water flows towards the blade core. This provides fins with immediate elastic reaction to the movement coupling, allowing rapid restarts, therefore resulting in excellent energy transmission.


Fin blades, in areas where water rails are not present, disperse 50% of the water they come in contact with. This is what the French call “drifting”. We make an effort to move water for thrust but we disperse it on the side. Therefore the forward thrust is low, and the action useless. The solution to this problem was invented in 1993. Constant water rails, inspired by racing car spoilers, were invented to keep water on the blades and not disperse it on the sides. Divers feel as if they were kicking on two rails. Water is not side channeled, blades do not twist and system efficiency is outstanding. Especially indicated for freediving deep dives, where constant speed is key compared to acceleration.


C4 has over thirty years experience in designing and manufacturing advanced carbon fiber equipment, in Italy. Our history is at the base of our brand success.
