The main feature of this mask is the field of vision which is almost completely non impaired. The field of vision is 30% higher, compared to a classic free diving mask such as the Alien. The internal volume is so low that if a mask as the Alien is normally compensated starting at the 8/9 m of depth, the ZERO3 does not require compensation before a depth of 18 m. This allows for a much more comfortable and enjoyable spearfishing.
Every detail on this mask has been conceived keeping in mind its design and functionality. The mask skirt features some milled surfaces that prevent the refraction of sunlight and ease compensating (gloves don’t slip when you hold the nose).
