Getting them off quick hadn't occurred to me - normal respirators are quite easy though - I can improvise a quick release if required. Does the air vent back through the reg or is there a separate exhaust valves on FFMs?
Sounds like a lot of fun to be had in the local pool!  |
I have only used the Ocean Reef FFM and the adapter came as supplied (I no longer have my adapter as I exchanged my first mask for a new one when I went for the integrated reg option). Instead of a mouthpiece on the reg there was a plastic tube which was threaded so it could be attached to the mask.
The air does not vent back through the reg because of the dead air space/CO2 build up problem. It vents out through a one way valve at the bottom of the mask (on mine).
Beware if you go for the comms and try them out in a pool - there was a story in one of the dive mags some time ago abt two blokes trying FFMs/comms in the pool. They were happily chatting to each other as they finned about the pool unaware that everyone else could hear what was being said. Unfortunately for them their conversation was along the lines of "nice arse, nice tits, I wouldn't mind giving that one etc". They were slightly embarassed when they eventually surfaced.
ONE VERY IMPORTANT THING I FORGOT TO MENTION - you will need to fashion some method of equalizing the pressure in your ears. On my mask there are 2 internal nose plugs (fully adjustable) that press onto the outside of the nose when I push the top of the mask to my forehead.
