TAC SCUBA FINS
The TAC fin is a performance leader in Ultra-High Performance Fins. The TAC’s operation is unlike any other fin in the market. This light, efficient fin propels you through the water with immense force. The TAC’s proprietary material, thin design, and curved blade provide a rigid cross-section that attacks the water. The fin length, width, open toes, and proprietary material have created the goldilocks’ zone for ultra-high performance fins.
This fin is the REAL deal!
Why buy TAC Scuba Fins?
The radius design, surface area and leverage points provide extreme propulsion you can feel. This fins performance in current is stellar!
The fin allows quick turns, directional changes, and maneuverability. This thin, firm, curve design maximizes
Shorter design and open toes mean less leverage on calf muscles. Fin design uses larger quad muscles
= reducing calf muscle cramps.
The fin weighs 1.9 lbs.

How leverage works with Scuba Fins
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.

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

Optional Carbon Stiffener
Warning - Carbon Stiffeners are suggested for divers with powerful legs. We suggest standard first, and if you then want a more rigid fin to add the carbon after a few dives with the standard.

You can add our Carbon Fiber with Kevlar stiffeners underneath the standard stiffener to tune your fins perfectly to your body and kick style.
Carbon Fiber with Kevlar Stiffener Rigid: Increases rigidity over stock fin by ~20%
