Tec Diving Journey / Seeking Advice

You had Yosemite Sam as your IT, huh?

He said ooga booga and grunted

Ah. I should have clarified. Across the dives I was in the range of 22 - 28% O2 - depending on the depth. Deco was 50% on a few and 80% O2 on the last one.

22-28% = Air

80%, just say no. Use O2.

If you find a Tech instructor who teaches deep air or 80%, its a good indication you need a different instructor. Sort of like meeting your airline pilot before takeoff at the airport bar.....take another flight.

@hammerhead_sm is diving in India. I’m betting the dive shops don’t have a booster to fill cylinders with 100% to full operating pressure. They transfill O2 into the receiving cylinder and then use air to get to the desired pressure. I had to settle for 80% in Saudi Arabia because there simply wasn’t anything else available.

I suggest take up a class. Like Gue Fundamentals.

Instead of compromising with the wrong mix, just use a larger deco stage tank and run lower pressures. The bounce dive profiles that we're discussing here don't require a huge volume of O2 anyway.
