BTS Hydro™ 4x Carbon Blades

Features: 

  • 4x4 Carbon Fabric (vs. 2x2)
  • Shark Skin Finish
  • Concave Water Rail
  • 81cm Length
  • **NEW** 27 Degree Angle

We are proud to announce a next level carbon fiber freedive spearfishing fin! Meet the Hydro™ 4x Carbon Blades. They're feather light and high performance freediving bladesNew shark skin finish, and 4x4 carbon fabric (vs. 2x2) to increase energy transfer. The blade length is 81 cm, which I find to be the best propulsion without sacrificing maneuverability. New 27 degree angle lines up better with the body and proves more efficient. 

The 27 degree angle have better ergonomics, making kicking more natural and comfortable! The 27 degree angle blade will break the surface more easily, making surface kicking more comfortable and optimizing the power of the push through the water relative to effort.

The new concave water rail is designed to displace more water per kick for better thrust. So you use less energy per kick to propel through the water faster, covering greater distance in less time, using less oxygen. These fins are buttery smooth to kick, excellent for getting to depth faster and easy to pivot for spearfishing.

We guarantee everything we make. If you are not satisfied with one of our products at the time you receive it, or if one of our products does not perform to your satisfaction, return it to the store you bought it from or to Blue Tuna Spearfishing for repair, replacement or refund. Damage due to wear and tear will be repaired at a reasonable charge.  Warranty invalid if damage caused by misuse (ie - jumping off boat with direct water impact, hitting propeller with fins, kicking off bottom in shallows).

These will mount to all the top companies footpockets. The footpocket tendon, for brands like OMER, Riffe, Mares Razor, Salvimar, Hammerhead and more can easily attach to the rubber t-rail. You don't have to deal with a frustrating gluing process, unless you want to. These will also work with OMER Stingray Shorts, Pathos, Mares Razor and Beuchat with slight modifications (shave off a portion of the rail that overlaps the fin tendon, glue instead of drill and use mounting hardware). 

When blades only are ordered, they do not have pre-drilled holes, so you can match them up to your footpockets.

It's time to step up your freediving & step into the Hydro™ 4x Carbon Fins!
