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.

and fits into a 
carry-on bag.

An ultra-light high-performance fin. 

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.

Key Points 

  • 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.

  • Longer stamina




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
