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?

THRUST/PROPULSION

The radius design, surface area and leverage points provide extreme propulsion you can feel. This fins performance in current is stellar!

AGILITY/MOBILITY

The fin allows quick turns, directional changes, and maneuverability.  This thin, firm, curve design maximizes 
mobility. 

EFFICIENCY-LEVERAGE.png

EFFICIENCY/ LEVERAGE

Shorter design and open toes mean less leverage on calf muscles. Fin design uses larger quad muscles

reducing calf muscle cramps.

LIGHTWEIGHT

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

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.

CARBON FIBER 
WITH KEVLAR

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%

INDIGO INDUSTRIES TAC Fin - the BEST Fin out - that's what he said

Check out why Indigo Industries TAC fin is making waves in the scuba industry. It has taken Indigo Industries 3 years of R & D to perfect the TAC fin. Now, this fin is unmatched in performance! www.indigo-industries.com TAC Key Features The TAC fin is the essence of performance through efficiency. ​ This fin is setting the bar for performance! Try it - your customers always say they will never dive another fin again! ​ 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 a quick transitional change in direction Excellent travel fin Fits into a carry-on bag. Features & Benefits WEIGHT 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, which translates into more bottom time. AGILITY 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. THRUST 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. EFFICIENCY 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 a 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.
