Hi Guys,
I am using a full face mask with my YBOD. The mask (Kirby Morgan Supermask) retains the normal mouthpiece bite in my mouth so when normally diving the deadspace is the same. However I was wondering if it possible to use the mask without the mouthpiece held in the mouth i.e. just taking it out the mouth but keeping mask on of course, the FFM will keep me dry.
I have heard talk about 'deadspace' in regulators and FFM.
Is this a real issue or a myth?
How do other FFMs work - especially when using comms? Do they all retain the mouthpiece bite in the divers mouth?
If deadspace and CO2 build up in it is an issue should I worry about fitting a OC/DSV to a YBOD or a FFM??
Any feedback would be appreciated.
