Hmmm Solo Diving.
I have 50 dives. Not a lot, but more than just out of OW. I am also a skydiver with over 300 skydives. I'm very comfortable in water. You'd think I'd be a safe bet to stay calm.
Recently I got VERY spooked by **** visability. OK I was at 30 Meters (100 feet) so I may have been narked. I made a very poorly controlled acsent with one of the dive masters. Luckily neither of us were hurt. More down to his skill than mine.
If I'd been solo I'd quite possibly be dead now.
It took a long time for me to get back in the water. Mostly because I knew I'd messed up. More recently we had an "incident" at 22 meters, we got separated from an instructor, and caught in a current, and just to add to the fun, I lost a fin. Did I mention that vis was ****. Anyhow I stayed calm and in control. Even then I was VERY GLAD of my buddy who was much more used to diving in cold and murky water.
Until **** happens you DO NOT KNOW how you will react. Usually if you get a chance to deal with the same problem again, you deal a lot better. (AKA experience)
If you dive SOLO without experience, you may not get to learn from your mistakes. If you have the experience and you want to dive solo, well you've WAY more dives than me - so why are you reading my advise ?
