The patented concept of raked lenses and their special “inverted drop” is developed further here. The lenses are placed as closely as possible to the eyes, with the further increase in the field of vision taken to the maximum levels possible. The soft silicone skirt has a new profile and a wide sealing ring for excellent grip and unprecedented comfort. The internal volume of the mask is exceptionally low, lower than that of many free diving models and the weight is decidedly low. Two pressure buckles, integrated into the headband, allow for quick and accurate adjustment of the strap. The surface of the snorkel has been treated applying a camouflage design for an original visual effect. When used in combination with other camouflage equipment, divers become almost invisible underwater!
The air between the glass of the mask and the face is the so-called. the internal volume of the mask. The mask sticks when diving, therefore the pressure exerts pressure and the internal volume decreases, as a result the mask sticks to the face. To avoid this painful moment, the internal pressure of the mask must be adjusted to the external pressure exerted by the water. This is achieved by gently blowing air through the nose.
The air in underwater sports is extremely valuable, so the equalization of pressures should be done with minimal effort.
For freediving and spearfishing, a mask with the smallest possible internal volume is required, providing easier pressure equalization.
