C4 Carbon Tank HD Blades (PAIR)

Price is for a pair of C4 Tank HD Blades. The TANK HD fins are characterized by small dimensions and a specific thermo-rubber protection on the tip. TANK HD fin blades are ideal for spearfishing in waves and foam, especially in cold and shallow waters. The blades, 70cm in length, have a protective edge for the tip that is over-molded onto the carbon blade, thus becoming an integral part of it. The blades are compatible with 350 and C4 450 footpockets. 100% MANUFACTURED WITH SOLAR ENERGY MATERIAL: Carbon Fiber T300 BLADE HARDNESS: 30 medium WATER RAILS: Elastic-K10 black FINS WEIGHT: starting from 550 gr DIMENSIONS: 70cm x 19 cm C4 Carbon 350 footpockets, with fixing kits, available separately. OVERMOULDING PROTECTION SYSTEM O.P.S. TECHNOLOGY O.P.S. is a revolutionary manufacturing process which features the over-molding of thermo-rubber to create a protective cover on the tip of the blades. It’s the first time that plastic thermo-rubber is being over-molded on carbon fiber. This has been a true challenge. We have conducted tests for over a year which our fins have successfully passed after 300 hours in the water. Over-molding thermo-rubber, compared to traditional gluing, has allowed us to work with specific dimensions and geometries which have not compromised the classic technical features of our fin blades (reduced weight, great elastic modulus and power).
