dedicated connector (medium size (if individually required: code 33021); a small size regulator connector (code 33020) is available as a separated accessory). The third port is available for the installation of an underwater communication unit. The 2nd stage may be installed in the front or left side of the mask. The in air weight is less than 600 grams (22.00 0z). The NEPTUNE II mask has a limited lifetime warranty.
Use of over-injected regulators Over injected regulators have a diaphragm with an inhalation crackingpressure below zero. These regulators “free flow” easily, and as a result, should not be used with the NEPTUNE II masks. Ask OCEAN REEF customer service for the best choice.
