AGA Full face mask

[jmsdiver]

FFM's are great at keeping your face warm in cool water. Furthermore, they offer a wide view of wherever you are (almost 180 degrees), can handle eye glasses (frames), multiple gas mixtures with the right kind of valve/switch, and communications support.

You should either take a class or find someone that is experienced in utilizing them to get yourself familiar with FFM diving. Things you'll want to consider are:

• Can you ditch the FFM and switch to an alternate supply of gas (remember the FFM has an integrated regulator, you need to know how to resolve the contingency of a free flow or failed regulator)?
  
• Do you have a way to carry an extra mask (remember that the mask in integrated in the FFM)?
  
• Comfort level with the FFM (take it easy for several dives as it is a different experience)
  
• Bouyancy characteristics (the FFM may change your bouyancy slightly and you may need to add a couple of pounds to your belt).
  
• How do you supply your buddy with air in an out of air situation? How does your buddy supply you air in an out of air situation?
  

I'm sure that there are other considerations, but that is all that I can think of at 4 in the morning.
