It's been a long road back from Covid, ready to dive again!

Hi @12th Man

Sorry about the bad assumption I made about your Jupiter shark dives, I was wrong.

2.75 atm is 1.75 atm over the 1 atm at sea level. 2.75 atm is a depth of just under 58 feet (57.75/33 +1 = 2.75). Unless, of course, they are talking about 2.75 atm over normal atmospheric pressure (90.75/33 +1 = 3.75). The former is the usual nomenclature.

No problem, it's all good. I was just going off the depth that the tech told me when she was setting up the chamber for my session. I will tell you I cleared my ears twice as much in that chamber than I normally would do when diving. At the 1.75 atmospheres the decompression was 6 min. Today the decompression at 2.75 was 12 minutes. Just little things I noticed having never been in a hyperbaric chamber. I was able to nap when not watching TV.
