Deep Apnea Euros 80cm Carbon Fiber Fin Blades

Overview

Deep Apnea Euros 80cm Carbon Fiber Fin Blades are designed for freediving and spearfishing, combining responsive propulsion with controlled flexibility for efficient underwater movement. Their multilayer carbon construction supports smooth surface swimming, precise positioning while hunting, and powerful ascents.

Carbon fiber construction and performance

The blades use Deep Apnea's Variable Parabolic Stiffness (VPS) design, which distributes flexibility through the carbon fiber layers to produce a responsive bending and recovery action. This allows the blades to store energy during each kick and release it as they return toward their original shape, supporting efficient propulsion with reduced effort.

The quadraxial carbon fiber structure incorporates fibers oriented at 0°, +60°, 90°, and -60°. This multidirectional arrangement increases resistance to torsional forces, helping the blades maintain stability during kicking. The responsive construction also supports controlled, low-vibration movements when approaching fish.

Stiffness selection

Choosing the appropriate stiffness depends primarily on body weight and leg strength. The blades should flex sufficiently during kicking to provide effective propulsion without excessive resistance. A blade that is too stiff can increase leg fatigue, while one that is too flexible may provide insufficient propulsion for the diver. Deep Apnea recommends selecting stiffness according to its weight and strength guidelines.

Footpocket installation and compatibility

Choose a Neritic, Neptonics, or Cressi foot pocket and the required Foot Pocket Size. Select No Foot Pocket for blades without foot pockets. Compatible foot pockets and the correct mounting configuration are required to use the blades as complete diving fins.

Confirm the intended footpocket model and mounting pattern before installation. Deep Apnea recommends mechanically fastened footpockets with full-length tendons and specifies approved footpocket models for warranty coverage. Improper drilling or installation can affect blade integrity and warranty eligibility.
