The TANK HD fins are characterized by small dimensions and a specific thermorubber 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 overmolded onto the carbon blade, thus becoming an integral part of it 

The blades are compatible with 350 and C4 450 footpockets
