What is your personal depth that CESA is option #1

    I assume we all agree that if one went out of gas at 10 feet that there would be no looking for another diver to share air. CESA would be the proper move. So what is your depth that is the grey area between doing a controlled emergency swimming assent and starting the process of getting another diver to share air?

    Probably 15ft. But it’s not option number one.

    I dive sidemount, even recreationally. If I need air from someone, something’s gone REALLY wrong.

    Yes Marie13 I am assuming no gas redundancy. However there is a correlation with my question and redundancy (If you get my drift).

    I'm typically diving solo with a 40 cf alternate air source. In that case at any depth I'd switch to it instead of doing a CESA. Even from my 15-20' safety stop. I'm not going to do a CESA if one isn't necessary. When I solo dive at Blue Heron Bridge if I had a gas emergency I would do a CESA. My max depth there would be about 25' but my typical depth is 10-12'.

    Without an AAS and diving with a buddy I would only choose a CESA if my buddy isn't right there. Even from the safety stop. I'm not going to do a CESA if it isn't necessary.

    So JimBlay I wouldn't bring my 19 cuft pony at Blue Heron Bridge and I assume you don't bring your 40 cu ft alternate because it is so shallow. Is this correct?

    So if you are doing a 25 foot reef dive in Key Largo do you bring the alternate air source?

    I’m solo certified. If I wasn’t diving SM, I’d be slinging an AL40 for a pony for single tank diving that was solo.

    Thanks for the responses. It may help to give more information. I don't have a regular buddy. Spouse doesn't dive. So if I'm in Key Largo diving I follow a guide. I may have an instabuddy. This has sometimes been an instructor with 5000 dives or someone who is new and clueless.

    On shallow reef dives instbuddies may not even be assigned, it is just a group dive. Of course the dive op knows me by now and doesn't worry about me.

    So if I do the Spiegel Grove at 90-100 feet I take my pony and will continue to do so.

    At Blue Heron Bridge I would not, maximum depth is 22 feet, usually 15 feet.

    I have not come to grips with if I am diving with an instabuddy or a guided group at what depth of a dive to take the bailout bottle.

    @FishWatcher747

    Sounds like solo would be a good choice for you once you have the minimum number of dives (100) required before taking the class.

    Never needed to but fell confident enough that I can do it from 80’ . On northeast wrecks I carry a pony bottle but never had to use it. Diving down south in clear warm water I see it as too much trouble to bother with.
