When I make a solo dive, which is not as frequent as it was before I was assimilated by my DIR buddies, I use the same gear and techniques as I do when buddy diving. I always dive in doubles, iso manifold, 55# wing, liftbag and drysuit. The only thing I do differently is not worry about my buddy. Most of my solo dives are as relaxing, if not more so than buddy dives. I don't change any limits so I'm not in a different frame of mind when solo. If I were to tell myself that I couldn't dive deep, penetrate wrecks, hunt bugs or stay down for two hours unless I had someone with me I would be cheating myself out of some excellent dive opportunities.
I'm with you on this.
My best overhead dives have been solo. I know going in that the only person who's going to silt up the site and blow out the vis, get entangled in something, lose the guideline, or have some other kind of serious problem is me.
Having made this decision I also know that if I do have any of those problems, and cannot solve them on my own,
I will surely die.
However, what I get in exchange for this is that nobody else will cause me to die on that dive - only I will be responsible for that, and just as importantly, I will not cause someone
else to die.
There is a trade-off here that most people who are either solidly on the "solo" .vs. "buddy" side of this debate are either unwilling to accept or simply wish to dismiss - that by diving solo you create one risk, but avoid two. Specifically:
1. If there's a problem you can't successfully solve alone, you will die.
2. You will not, however, create a problem that causes someone else to die along with you in a futile attempt at a rescue.
3. You will not also be a witness to someone else dying while you survive, either from a problem you create, they create, or you both jointly create, which may be even worse than (2).
This trade-off is
not simple to evaluate. All the cliches in the world, and all the cult beliefs about diving either solo or with a buddy do not change any of these facts - and they are facts.
Unfortunately the zealotry, particularly on the "unified team" side of this debate, clouds the issue. It postulates
Most of the time, people die when diving because they fail to think. They either violate one of the cardinal rules for the environment they are diving in, including all relavent factors (they fail to think before they dive), or they fail to think when a problem occurs underwater (they fail to think while diving.) The remainder of the deaths are unavoidable except by perhaps not diving at all (e.g. a physiological problem - which might have killed you on land as well as under the sea.)
In truth, as long as I have gas, all is ok. Oh sure, I might have something happen that would cause stress (e.g. entanglement, loss of vis, etc) but so long as my breathing supply remains adequate its all something that's a "situation" and not an "emergency."
The only true emergency is a loss of breathing medium.
Until you get to the point in your diving where you are comfortable with all of the above, you are not ready to dive solo. Exactly when a particular individual IS comfortable with those things varies from person to person and with the environment; it could happen in 50, 100 or 1000 dives, and it could happen never. I suspect that for the diver who trains and dives in locations where his or her "recreational" dives tend to be more challenging (.vs. a caribbean reef) is likely "ready" sooner than one who only dives on 20' deep reefs in the caribbean.
