Sorry to hear about the disappointment. Out of curiosity, was the dive buddy someone you usually dive with? If he/she was a new one, then it might either need some getting used to or keep looking for a good one. I totally get your frustration. I got paired up with a diver with similar experience during a recent dive trip (we were both solo divers). That guy was far more interested in wandering off with his GoPro than staying close to his buddy, me. He never bothered to signal me when/where he was going, and too many times I turned to check upon him and he was 5-10 meters away from me and/or on the other side of a reef/wreck. He never checked on me for the 4/5 dives we did together.
I wouldn't so much say it was a disappointment in the sense that it made me angry or anything, just that it surprised me and brought home ho quickly things can go from 'hey nice dive and I chilled out' - to 'bl**dy heck, I nearly just drowned myself and nobody noticed!'
We are both club members and have dived together several times, and I would say that during the dive he was great, visibility was very poor, sometimes only 2 or 3 feet, we did a proper buddy check, had a proper dive plan, i.e. directions and distance to each feature we were going to try to find, and we constantly communicated on direction and who would be where. From that point of view the dive was great. It was just the shock of falling over when we clearly both thought the dive was over and we were safe and winding down.
There is one guy at the club like your Go-Pro man - he likes collecting freshwater crayfish, and he is an ok buddy right until he sees one. Then he is like the dog when someone throws a ball - off he goes and forgets everything else, he'll happily go 10 or 12 metre chasing one - which when visibility is only 3 or 4 metres at best means that if your not watching you get separated very quickly. Unsurprisingly most people don't like diving with him, and avoid him like the plague. He's been told countless times, he is contrite and apologetic, behaves for a bit, then hey - theres goes another ball - woof!
Hi Eric - I have seen what you mean - someone posted a link to so youtube videos of surf entries at Monastery (a.k.a. Mortuary) Beach - not sure if that was So-Cal but that is some scary surf.
Best - P
