C4 Martin Stepanek Blades Only

C4 Martin Stepanek Blades Only

One pair of blades without footpockets.

This project was the result of the exceptional experience of Martin Stepanek, one of the greatest competitive freedivers of all times, combined with the 30 years of experience of the C4 carbon fiber fin Co. of Marco Bonfanti. Stepanek’s signature fin features TR50-Hypertech Big Square, an even more responsive carbon fiber material compared to the already highly proven T700 adopted previously by C4. 

After a year of long testing, Martin carefully developed a fin with C4 that fit his needs and catered to the most important needs of freedivers and spearfishers from his experience in American waters. 

Features of this signature C4 fin:

• NEW Industry unique TR50 Carbon fiber construction.

• 780mm Length (30.7”)

• 190mm Width (7.5”)

• 10mm Water Rail height

• 22 Degree Angle

3 Stiffness options: 

  • 25/Soft – This stiffness is suited for divers who weigh -175lbs, diving between 20-80’ with a mix of surface swimming and deeper diving/spearfishing.
  • 30/Medium – This all around medium stiffness is intended for divers who weight 175-210lbs, engage in surface as well as a mix of shallow and deep diving to 30 meters (100’).     
  • 40/Hard. This stiffer blade is generally indicated for bigger divers weighing over 200lbs or with a strong preference for deep spearfishing to a depth of 40 meters (130’).  The stiffness of the blade renders this blade stiffness choice well suited to overcoming added negativity at depth and rapid acceleration requiring more power and energy from the divers’ legs.  The 40 stiffness are not recommended for beginners and lighter divers as they can contribute to ankle strain and reduced bottom times.
