Full face masks for cold water diving

[dfreeman]

Good discussion on Full-mask units.  I haave tried several and the ADA is a great mask.  I would agree that the ambeint air port is a required feature.

Ear clearing is done by pressing your nose agains 2 pins whit then squeeze close te nostral and then blow.  Takes some adjustment but is realatively easy to master.

Hope this discussion helps you out.
