The ScubaPro S-TEK Fin OH is a heavy-duty open-heel fin built for technical diving. Part of ScubaPro's S-TEK line, it is moulded from dense rubber that makes the fin negatively buoyant, which helps divers hold a stable, horizontal trim.

The stiff paddle blade gives powerful, precise thrust and suits the controlled kicks technical divers rely on, in particular the frog kick and back kick used for fine positioning and to keep silt down in overhead and low-visibility environments.

A stainless-steel spring strap takes thick boots, cold water and dry-suit diving, and snaps the fins on and off quickly. For Indian divers moving into technical training, the S-TEK OH is a tough fin.
