APOLLO BIO FINS PRO
A standard for navy and dry divers: Apollo Bio-Fins are made of solid rubber. These kinds of fins have long been essential for use in the navy.
They offer ideal power amplification and, above all, they are not buoyant, minimizing the risk of the fins breaking through the surface of the water. And if a fin is lost, it sinks to the bottom.
Advanced dry and DIR diving also benefit from this advantage, because the heavy section of the fin optimizes the water position and ensures a clean frog kick.
