As seen on Discovery Channel's Shark Week with Paul de gelder
The TAC fin is the essence of performance through efficiency.
Ultra-High Performance Fin
- The wide tips slash through the water with optimal thrust
- The shorter length reduces the overall strain on your legs
- This agile fin design allows for quick transitional change in direction
- Excellent travel fin
- Fits into a carry-on bag.

Features & Benefits
Finning is a start stop motion, like lifting weights. There is less strain with less weight. Tac fin weighs only 1.9 pounds compared to other High-Performance Fins that weigh as much as 5! We do this through a proprietary compound that is stiff and because it is stiff we need less material which makes it very thin. We also use a curved fin design to add rigidity. No giant masses of rubber ribs on each fin, the sleek, thin design at less than half the weight of other High Performance Fins means you get less tired, and that translates into more bottom time.
Thanks to TAC’s proprietary material, thin design, and curved blade we have a very rigid cross section. This means when you turn in the water, the sides of the fin cut through the water instead of having to move a large mass and “sailing” (bending the fin sideways.) This makes tac the most agile fin on the market! In military testing TAC Red Label beat every fin tested hands down in agility underwater.
Tac’s shorter design provides more rotational control. This in turn supports a stronger kick and allows a slightly wider blade for a larger bite. Stiffeners on top of the fin blade engage on the power stroke to add thrust to the stoke that provides 90% of total thrust. They release on the recovery stroke to conserve energy. Carbon stiffeners can be added to tune the fin to your body and kick style.
The shorter design reduces the leverage working against the diver. Additionally, the open toe means we can reduce it further and use the section under the toes as working fin surface. Plus, the load is transferred to larger quadriceps instead of weak hip flexor muscles. Power in vs power out. That is ultimately what defines a great high-performance fin.
Optional Carbon Stiffener
You can add our Carbon Fiber stiffeners underneath the standard stiffener to tune your fins perfectly to your body and kick style.
Carbon Stiffener Soft: Increases rigidity over stock fin by ~10%
Carbon Stiffener Rigid: Increases rigidity over stock fin by ~20%
Frogger Carbon Stiffener Soft: Increases power stroke rigidity by ~10%, Recovery stroke which is used for thrust in Frog kick increased by 20%
Frogger Carbon Stiffener Rigid: Increases power stroke rigidity by ~20%, Recovery stroke which is used for thrust in Frog kick increased by 35%
