Our design teams created this diving mask for freedivers. Enables you to freedive in the sea or in a pool.

The enlarged upward field of vision allows you to look up to the surface without raising your head. This reduces the risk of losing consciousness (syncope) when returning to the surface.

BENEFITS

Field of vision

Vertical field of vision: 96 ° (M). Horizontal field of vision: 117 ° (M).

Durability

Two window, scratch resistant tempered glass.

TECHNICAL INFORMATIONS

Internal volume

The volume of air inside the mask, between the face and the lens, represents the internal volume.
For free-divers and spearfishers, the internal volume of the mask must be as small as possible to facilitate equalisation.

ADAPTED FIELD OF VISION

There is a risk of losing consciousness (syncope) during a freediving session. This risk is even greater in the last 10 metres before reaching the surface.
It increases further still if the freediver raises their head to look up at the surface.
To reduce the risk of such a blackout, our design teams have developed a mask shape that increases the upward field of vision, without the diver needing to raise their head.

Equalisation

The mask gets pressed against the face when diving. As you dive, pressure gets applied to the mask's soft skirt, reducing the internal volume and pressing the mask against the face. This phenomenon, which can cause pain in the eyes, can be avoided by equalising the internal pressure of the mask and the external pressure applied by the water. Simply breathe out gently through your nose. Air is very precious in underwater sports, this equalising effect must be kept to a strict minimum.

Silicone

Silicone is an extremely flexible material. A silicone skirt fits flexibly to the contours of the face, creating a watertight seal.
