I see.
So what you're looking for is indicators that will tell you when you're ready....right?
Number of dives isn't one of them.
There are several things you need to just do:
- get your gear sorted out for solo diving. Full redundancy
- find a suitable site, which involves diving a lot of sites with a buddy first
- think about your planning as more than just the bit under water, think door-to-door.
- acquire and/or hone certain skills (handling redundant gear, self rescue, basic scuba skills)
As a diver, you need to possess:
- calm demeanor under all kinds of pressure
- discipline
- awareness of your boundaries
- acceptance of increased risk (which also applies to the people around you!)
- organisation
- a thick skin, people will pester you.
As a minimum training level, rescue
That's a start. See where I'm going with this? You started asking how many dives you need but you don't need a whole whack of dives. Other qualities are more important and even some people with enormous numbers of dives don't have what it takes to dive solo. These two things are not even remotely related.
R..
Pretty much sums up the "when are you ready part"...
With regards to training though, I dont think the piece of plastic is as important as the actual knowledge and mental preparedness..
My first solo dive was probably around dive 15, but it was a very shallow dive in an area where the biggest risk factor is hitting a moose driving to the site I dove..
No entanglement hazards, no sudden drops to depth, no loose rock I might be unfortunate enough to get stuck under as they come down and so on and so forth.
I had a lot of stress management training and experience already and knew I wouldnt be the paralyzed type in the event of an emergency. I also where unfortunate enough to experience my buddy having gear issues at 100 feet and shooting to the surface at well over 3 times the recommended ascent rates. When I was at 80 feet I had to make the choice of wether or not I was gonna try getting to her and saving her ass. As it happened there was other divers at the surface waiting to get down, so I decided that one accident is better than two and I wouldnt do anything but complicate the situation if we had two accidents, so I ascended to my safety stop, where fortunately she was hangin on to the rope as hard as she possibly could. That dive ended with a safety stop that was rather long..
After starting to dive solo I also grew a different attitude towards diving in general. If I cant rely on myself saving my own ass, why should I rely on someone I maybe bare know to save mine, or me to be able to save someone else for that matter?
It basically widened my attention to possible problems and how to deal with them as well as gave me some insight into how blindly one can trust a buddy that you dont really know much about. Its not really a matter of not trusting a buddy as much as it is a matter of making sure Im prepared to do the dive myself.
Also, if Im planning to do a solo dive and dont have any warning lights going off as to possible dangers, I dont do it as im not in the right mindset that day. Theres always dangers and if I dont even have one pop into my head while preparing, theres something I dont see that I should.
First night dive?
I tried to do one once just to test out some new lights, however I didnt feel comfortable with it once I was at 10 feet, so I just aborted it and left it for another time.
