Hi, What OceanReef mask do you have? Is it the Neptune II? I started with the Neptune II and it worked well for me, after that I got the Neptune space, now I'm using the Preditor. It works like a dream.

I've never used a rebreather with the OceanReef masks, of course, I thought I would give out this information to you. Don't know if this will help you but I thought I would just give you the info.

It's down below.

I'm working on my own rebreather system that willmake it easier for me to get deeper.

Safe diving Matt

NEPTUNE II NIRA with

REBREATHER

The Neptune II mask and even the Neptune II NIRA may be used

with rebreather. The attached picture rappresent the application

of the Neptune II NIRA with a rebreather for military appliaction by

Italian CONSUBIM (Italian Special Forces) Neptune II configuration

allows the application of a rebreather, however due to the differ-

ent models available in the market each one must be connected to

the mask by different ways. The 4 ports available in the mask (the

2 sides, the front and the botton) allows to apply the In and OUT

hoses from and to the rebreather and have additional ports for the

communication unit or for special adapters.
