I only scuba dive with a partner.
I was shocked to learn while in Roatan a couple of years ago that PADI has a certification for people who dive alone. WTH?? I got certified PADI/NAUI/YMCA 42 years ago and the cardinal rule was always NEVER DIVE ALONE.
As a solo 10 day type backpacker and solo (small time) climber, solo white guy in a black bar, and such, I understand the attraction of solo diving, it is easier to die, but then again, you can dive when you want and live your own life, without being overly concerned about when and where you will die.
Ha Ha! Your old.
As a foolish twenty-something I was on a boat excursion on the Great Barrier Reef. For extra $20 they would rent scuba gear and give you a lesson. “Put the breathing thing in your mouth”.
The guy I was with thought it was too risky. What a wimp. Thankfully my stupidity didn’t kill me. A large shark swam below me (much larger than me), and there was one of those huge clams on the bottom far below me like from a Popeye cartoon. It was really amazing.
And then snorkeling on a shallow reef which was amazing. About the only thing I’ve ever done that was better than what you would expect from watching those nature shows.
The Grand Tetons, Yellowstone, Grand Canyon, etc. look a lot better on those shows than in real life.
