Blade replacement for long Cressi Gara Modular Impulse freediving fins. The Gara Modular Impulse Blade is made of high-modulus propylene (2500 Mpa). The blade is made of long-lasting material, very reactive, and highly elastic return. It incorporates two little antiskid spoilers on the final area. The decreasing thickness section (from 4mm to 2mm) causes the highly progressive tonnage eliminating the skid tendency because the first half of the set is more rigid and the final half is more flexible. The Impulse blade features an angle of 29 degrees, providing the ultimate in efficiency during the kick cycle requiring less energy.
