I’ve got about 30 dives so far and think of myself as safety concious. I read extensively, have a 19 cu ft pony that lives on the side of my main tank just in case, and am detail oriented. I am comfortable in clear water, becoming less uncomfortable in low vis as time goes on. I am thinking that one of the next things I should do to improve my safety skills, (apart from an upcoming AOW course and then eventually Rescue), would be to practice CESA. (Technically we did ONE, from about 15 feet during OWC but it’s barely a dim memory and didn’t seem real at the time if I recall.)
My question is what is the best way to do this? I ASSUME the best way is to do it near the start of the dive, and from around 25-30 feet. (This would be in a quarry with limited viz in the shallow areas on the weekends.) Since I know it means blowing off the 15 foot stop, does that mean it would not be ok to do it later in the dive after being down say 30 min between 30-70 feet? Also I assume the buddy should go up also, side by side, (breathing normally off her reg.), but should she blow through the stop also? Finally, as long as I exhale, how fast can I / should I go up? (Gotta know that in case I ever have to do a real CESA from deeper.)
Any advice is appreciated.
