Comments about Ocean Reef Ocean Reef Neptune II NIRA 6600 Full Face Mask with 6600 1st Stage:
Taken the mask to Cozumel, Hawaii and local diving. YOU MUST read to learn how to use it.
1. put on tighten center strap, then lower strap lthe last it the top one.
-Adjust air flow screw when at bottom= use less air.
-Does free flow at certain angles. You learn to avoig them.
-Go to pool to learn to adjust it. Not your learn at the dive mask!
-If you do not adjust it well= leaker!
-take your time with the nose plugs.
-learn to relax to save air.

Tank life shortened, I suggest that you use a double tank set up. That way you get max time, with out having to re-surface.

This was my first FF mask and its a good product but air comsumption is bigger with this kind of mask, I recomend it for those who wants the benefits of a FF mask over air durability.
