ABC

Mask, Snorkel and Fins

The ABC equipment for sports and technical divers consists of a mask, a snorkel and the fins. The diving mask (also named pressure compensation mask) also covers the nose, so that a compensation of the internal pressure of the mask can be carried out. The nose gutter is flexible to allow nose compression for the Valsalva trial. These two methods of pressure equalization are necessary to prevent the risk of barotrauma. The ABC equipment alone is sufficient only for snorkeling and freediving.

Mask types: Single and Double glass masks
