The Mares Volo Power scuba fin is an open heel fin, commonly used for scuba and snorkeling. This fin is popular as it accommodates boots, is comfortable, efficient and lightweight.
The fin has ABS plus buckles, an OPB system for great kicking efficiency and channel thrust technology.
Optimized pivoting blade allows the blade to maintain an optimal angle throughout the kicking cycle, whereas traditional fins achieve this only during a small portion of the cycle. OPB produces a constant thrust, which minimizes fatigue and produces fluid movement through the water.
Channel thrust is where soft longitudinal inserts allow a controlled deformation of the fin blade while kicking. This channel shape moves a greater amount of water resulting in more thrust for the same effort.
