was MOF for distress ever in the new science of skin and scuba diving? the text book for many old divers. I am one
Have not seen it in Editions 1 - 4. Will check editions 5 and 6 tonight.
Here is the only reference I could find, from TNSOSASD Edition 6, published 1985:
"Make sure that the mask is securely in place before entering the water, and do not remove the mask from your face until you are back on the boat or on dry land following the dive."
No mention of MOF = distress.
