DandyDon:
Pony bottle close to dry at end, back gas - which I'd returned to -still had 500#. Really okay there.
Ok, there are 2 components to what you did:
1/ Less efficient search
- Discussed in my earlier post - not calling in backup, going down immediately as opposed to a shallower bubble search, etc. Lots of good info there - not meant to replace a Rescue course.
2/ Extra risk incurred by going back down to depth on a used tank
- In principle, going down alone puts you at greater incremental risk and violates one of the basic premises of rescue: you now run the risk of going OOA yourself, you take on all the extra risk of solo diving and you are also doing a purportedly riskier dive profile.
I'd expect an experienced diver to be fully aware of these issues, take them into account and make their own assessment. OTOH, I would be horrified if an inexperienced diver chose to take these risks, as they are in no position to assess those risks or make that decision.
My rule in this sort of case would be "if you have to ask, you are not ready to do it" - the fact that you are doing so indicates to me that you perhaps were not in a position to do. OTOH, you do have a lot of experience, so without knowing you, I dont want to say for sure.
I will say that if you converted your remaining gas and NDL into remaining bottom time, then you were doing ok. OTOH, if you just blindly relied on the pony to bail you out - as it seems from your original post - you didnt do too well. You might have been "really ok" here - but in another situation, you may not be.
Tried. Always try...Yeah, with his crippled wife waiting in their car. :11: Again, thanks.
As a dive instructor, I can never recommend doing what you did. As a person, I salute you for taking the extra risk to save a friend (even if that decision was not rational, not the safest of decisions and not fully thought through).
If I had a friend go missing while diving, I'd be searching for them till my tank was dry. I am alive today because someone went above and beyond the call of what they should have done as a buddy.
That being said, still put me down more in the "bad idea" camp as opposed to "good idea" camp.
And general caveat for any beginners reading this (and at the risk of repeating myself): just because I am saying that I am ok with one individual deciding to go back down an look for a missing buddy does NOT mean that I am ok with this course of action. It is not safe - it may be ok for an experienced diver, who is fully aware of all the hazards, to take on the additional risks, but it is not ok for someone who doesnt understand all those risks to try this course of action.
