I was in Vancouver, BC at the time, and all the diving that wasn’t just wading in from shore was technical, due to the depths and the temperatures. So drysuits, nitrox, argon bottles for insulation in the cold, that sort of thing. It’s a fascinating world, but that time I had to do an emergency, no-air ascent from pitch black 110ft down after an o-ring snapped in my regulator kind of told me it wasn’t a life-long hobby.
