The TAC is the optimum combination of size and with for unprecedented performance.
Modeled after its military counterpart, the TAC fin provides superior thrust and maneuverability.

This fin brings carbon fiber,
lightweight, style and
propulsion to a whole
The DEFIANT XT is taking the blade fin to the next level. With a bi-directional design, it carves through currents and provides exceptional thrust.
The Adaptive fin is designed to provide amputee divers with independence in the water. The fins are engineered above the knee and below the knee amputations and feature an adjustable strap to adjust to individual needs. Perfect for adaptive scuba divers and swimmers.

How leverage works with Scuba Fins
Competitor Fin length
Stamina increases with lighter weights. The human body performs better with lighter weight and more repetitions. (Think bicycle cadence)
The leverage on long fins increases the weight on your body.
Shorter fins equal
Less weight on your ankle
Every stroke is easier to achieve
Less weight on your foot (far less cramping)
More kicks that are easier to achieve.
Long fins equal
More weight on your ankle
Every stroke is harder to achieve
More weight on your foot (far MORE cramping)
Less kicks that are harder to achieve. (example of fins = 46% Harder to kick)
Far less stamina
Weight on your ankle =
Increase weight on your ankle of 46%
Weight on your ankle =
Our bodies perform best over a long period of exertion when the weight we carry is light. Scuba is no different. One of the laws of physics is the effect of leverage. It is not changeable... not even with fins. The longer the fin the more leverage it has and that leverage is working against you as shown below.
