I feel your pain! Part of my cave training is to successfully find the main line without a mask and then exit! I certainly didn't feel like flotsam, either. In fact, I found it not only fun, but exhilarating. I recently did the skills test to become a Raid instructor, and that included swimming 30 feet without a mask. I maintained perfect trim and buoyancy through the whole process. Again, it was fun and exhilarating. I guess that not everyone sees the value.
Guess the message is not getting across....masks off or on forehead or back of head does not necessarily mean a diver is panicked...that was stated in several post....I assume that was an affront to some who put the mask on backwards or routinely put the mask on their forehead....get over it, no evaluation of you was made....but to brush off the fact that many times panicked divers often try to "escape' by shedding gear including mask goes against actual experience of those who have observed and dealt with panicked divers in the water.....this is not theory...it happens... disregard and you may not recognize a diver needing assistance...
Flotsam....again check how thin skinned you are....the reference was to the fact that loss of a mask disables a diver....sure from perhaps 4,000BC divers have gone without masks underwater....you can swim around UW without a mask; and divers should have this as part of their open water training.....but in our world divers need masks to be fully functional and safe underwater....I have never carried a 'backup' mask but there is a reason divers in overhead environments carry a second mask....can you grope around UW without a mask? Sure. Do you have the same ability to deal with situations without a mask? Of course not. Flotsam....something at the surface that does not does submerge; a diver at the surface without a mask should also not submerge...get it?
Can't believe that these points are contested or denied. Not that I have all the answers to anything but experience has taught me to verify that a diver in the water shedding gear or without a mask may need my help.
