...realized that I was the only one I could depend on to save myself...
This advice often doesn't seem to propagate beyond "solo divers," but IMO is essential for all divers. The "dive industry" appears to intentionally avoid acknowledging that a dive buddy may often be unable to assist
(due to incompetence, training, availability, their issues, separation, low-air, etc). Even if that (insta-) buddy was able to assist 90% of the time (haha), that last 10% is awfully scary. The industry is often happy to recognize all other kinds of problems on the dive itself, including out-of-air, equipment issues, boat-traffic, entanglements, etc.
I think safety overall could be improved, if divers were encouraged to think more about how they would self-rescue with no assistance.
(1) solo has some advantages over buddy diving, but safety isn’t one of them. Either people make bad buddies or have had bad experiences with buddies, but (2) two divers who understand and conduct themselves properly will always be better than one.
(1) That's a generalization, perhaps good enough for inexperienced divers, but isn't strictly true.
- A buddy can be a distraction
- A buddy may encourage dangerous behavior
- A buddy may behave dangerously, especially when in need of rescue.
- Over-reliance on a buddy for rescue may endanger both divers.
- Assuming the buddy can assist, may lead to diving beyond limits of self-rescue.
(2) Assuming 2 competent, properly behaving, and equipped divers might make "(1)" true. However, this goes back to needing to acknowledge that divers often aren't those things for various reasons (ego, inexperience, recent experience, inattentiveness, carelessness, etc).
When I look at an accident-or-incident, the analysis doesn't usually start with
"he had a competent buddy, well maintained and sufficient equipment, proper skills, gas-planning, redundancy, etc...." where everything is as it should be 99% of dives.
