Had a talk with an old salvage diver last week that flipped my view on comms gear

I was working a dock repair job in Norfolk and this guy who started diving in the 80s saw my setup. He told me I was spending way too much on fancy wireless units when a simple hardwire system with a good backup line does the job 90% of the time. He said he lost a diver once because a battery died mid-job and the backup never got tested. Now I test every single cable and backup unit before I even step off the boat. Have you guys ever had a comms failure that made you change your whole routine?

My buddy Dave had a backup air line fail on him once, not comms but close enough. He was doing a hull inspection and his main umbilical got nicked by a prop blade. The backup line had a slow leak nobody caught because they never pressure tested it to full depth. By the time he noticed his gas was getting thick he was already starting to feel it. Now I test every piece of gear like it's the only thing keeping me alive that day, air lines, cables, everything gets the full treatment before I suit up. Have you ever had a backup piece of gear let you down when you needed it most?

Redundancy is the only thing that saves your ass when shit hits the fan.
