Scuba diving with full face mask?

Question

who has scuba dived with a full face mask.what are they like.

Answer 1

They're more fiddly to fit and adjust.  And it can be harder to clear your ears.  Visibility depends a lot on the make of the mask.  A full face mask will have more drag going through the water.

They're most often used by working divers that don't move around a lot, and need to use a comm system.

Answer 2

They're warmer for starters. What is it exactly you need to know? Clearing? Equalizing? Comms gear? Heads up display?
