Choose your blade length:

• 560mm: This shorter length provides more dexterity. Good for instructors, underwater photographers, and spearfishers navigating reefs. Good for rocky entries and exits. 
• 820mm: This medium length provides a balance of dexterity and momentum. Best choice for beginners, and freedivers who want a good all-round option.
• 1000mm: This longer length provides phenomenal momentum during deeper dives, but takes longer to get going and is less maneuverable. Best for advanced freedivers and competitors. Not advised for beginners and those navigating rocky terrain.

Choose your blade stiffness:

• Soft: Least tiring for the legs. Great for smaller people and those who prefer to fin more softly. Great for competitors for avoiding lactic acid buildup on extremely long dives. 
• Medium: Provides a balance of comfort and acceleration. Great for medium sized people and those who want a good all-round option.
• Hard: Most tiring for the legs, but also most power on tap. Great for large people (100kg+), if you are diving in cold water with heavy weights, or plan to fight strong currents or big fish.

Choose your blade angle:

• 26°: This more acute angle provides a harder fin feel. Good for people with more flexible ankles. Holds more tension in the calves during freefall.
• 29°: This more obtuse angle provides a softer fin feel. Good for beginners and competitors during long freefalls.
