I have noticed follks just breathing on the reg without looking at the gauge a number of times. I always do the breath test while looking. Saved my tail in mexico where a new crew man had only cracked open my tank before a hot drop.
I will add I usually do my own gear set up but this was a very small boat. We took off gear in water and passed it up onto boat and then climbed aboard one at a time. By the time I was on the boat and in my seat my gear had been switched to a new tank. Was my own BCD and regs.
