Most divers (including me) have been calling scuba gear “Life Support” equipment since the beginning. However, when considering redundancies, dive buddies, and proper SESA (Simulated Emergency Swimming Ascents), is our life truly dependent on this gear. And if so, is it truly life support, whereas if the gear fails we die?

After a deep dive into this term we’ve all been using since the dawn of scuba diving, I believe Frank Degnan has a great point.

Frank has been a scuba instructor for over 40 years, former Dive Safety Officer at Universities, is active with three agencies (PADI, NAUI, and one other). And even holds the title of Course Director Trainer with NAUI. 

He has won awards, teaches adaptive curriculum, and remains active in his local diving community. 

This is a well-articulated approach to recreational scuba diving and labeling gear “Life Support”. 

It’s also a bit of a wake up call for how we train scuba divers and students how to properly execute Emergency Swimming Ascents, as well as knowing when it’s time for a redundancy system (such as a pony bottle, etc.)

I ran into Frank by happenstance while visiting the NEX Underwater Products warehouse in Monterey Bay, CA. This was neither scripted or planned, but we were already shooting content with the camera and mics when he walked in. His articulation of this topic stopped me in my tracks, and he was kind enough to let me record our conversation in virtually real time.
