But but but some of us like collecting tools, there's hours of procrastination being able to select the right table saw, reading reviews, etc.
Just like an underused table saw, an underused rebreather is an expensive ornament and a dangerous diving tool; competence is earned through lots of practice and it's rather volatile, slowly ebbing with disuse.
The point is I like my rebreather. I'd happily dive it in a shallow puddle, a pool, anywhere.
To that end I must get around to disposing of all my open circuit diving kit that cannot be re-purposed for CCR. It needs a loving home.
