The Ocean Reef Space Extender Neptune III is their most advanced full face mask yet for a modern and safer approach to scuba diving that feels natural to use. Comfort, safety and smooth breathing were paramount during the design and development of the new mask.
The Neptune III is an all new design that massively improves upon the Neptune II by considerably extending the field of vision by up to 20%, improving freedom of movement and improving visor clarity. The integrated second stage has also been completely redesigned for easier maintenance, servicing and swapping out if required.
The Neptune III offers a new visor geometry and orinasal pocket that minimises the internal volume, by 13% less compared to the Neptune Space. This orinasal pocket is the most anatomically designed on the market. The new pocket and visor design combine for minimal dead air space and internal volume.
Even the Quick Release tabs have been redesigned to increase their surface to more easily grip them. The Neptune III also includes a one-hand accessory removal handle to make removal of the integrated dive mask much easier whilst carrying equipment in one hand.
The Neptune III is supplied with an Ocean Reef backpack to safely store and protect the mask when not in use.
