Tusa fins are fins ideal for free diving or spearfishing. Some fins are not well-constructed, but these ones make use of split fins, as well as open heels.

Tusa X-Pert Zoom Open Heel Split Fins (SF-8) – Blue – Medium The Tusa X-Pert makes use of a ground-breaking hydrofoil design that generates lift or forward motion while requiring little effort from the diver. Just the same, the elastic material that the fins make use of are state-of-the-art and have a strongly reinforced construction that makes use of double layers. The fins also make use of its “propeller-fin technology”, for maximum comfort and enhanced performance. The fins follow a design that is angled, for increased effectiveness in kicks. Some designs may not be as effective, and propulsion may be inhibited by the design of these fins. When the leg is extended fully, a 27 degree angle stays between the leg calf and the heel of the foot. This is not something that Tusa fin users worry about at all. With these Tusa X-Pert fins, the very same angle is incorporated right into the fins. Whenever the leg is completely extended, despite the angle that may exist between the calf and the heel of the foot, the fin sits parallel to the leg and ALL of the expended energy serves the diver, whenever he kicks. |
