Perhaps. But where should people start if they’re scared of going under water but want to try scuba? I’ve been watching my girlfriend go through her OW confined water dives (literally - I’ve been training in the same pool whilst she does her pool dives so I can see how she’s getting on, provide moral support and understand any weaknesses as we’ll be dive buddies next month if she passes). She was scared of diving and claustrophobic before she started but she’s had a patient instructor whom I dived with first to ‘check him out’, and three pool dives in she’s getting the hang of it; she also found that of the four students that one of the others was the most anxious. From what I can see she’ll pass her OW and be able to come and do some easy diving with me just fine. Will she be joining me wreck diving at 25m in low visibility and cold water? No, but she will be joining me at 8m in tropical seas to look at fish, and so she doesn’t really need anything apart from OW. We’ve already decided that she doesn’t want to do AOW or anything else, when all she wants to do is ‘look at pretty fish and try something new.’
The confined water dives are there to get new divers comfortable with breathing underwater (amongst other skills). According to this advice she should never have been allowed to start, with which, respectfully, I disagree. I think it’s important not to forget what it’s like to be a beginner, and that not everybody has the same starting point or the same ambitions for their diving (ie to be the most highly skilled diver possible and to do fundies). Scuba needs to be welcoming or it’ll die out.
