18 years in and I just learned my bailout valve was set wrong
Been diving since my first Gulf of Mexico job in 2007, always checked my regs and hoses like everyone taught me. Last month during a platform inspection off Galveston, a green hat asked why my bailout pressure was at 180 and his was at 200. Nobody ever told me the setting changes if you're doing mixed gas vs air, so I've been running rich the whole time on shallow jobs. Anyone else find out a basic setting they've been screwing up for years, or is it just me?
