A low volume mask has a much
smaller air space inside it. This is the only kind
of mask that freedivers should use. It's because
the last thing freedivers need, is to waste their
precious air on equalizing a lager volume
mask. ::Top
Can I use my freediving (low volume) mask
on SCUBA?
Yes, absolutely. Not only that, but a
low volume mask is both more enjoyable and practical
than a SCUBA mask; being lighter, less obtrusive and
much more hydrodynamic. ::Top
