I have been fascinated by this thread.
I am from New York, but now live in London with a divemaster husband. A bit of history on me: I'm a woman who works in a man's world - I was an engineer, and now manage a large group of alpha males in a manufacturing environment. I'm reasonably well paid and am fortunate to have a bit of disposable income. I cycle in London, have been a motobiker in the past, and like me a bit of photography, none of which are cheap / safe hobbies. I'm not trying to brag here, but put a bit of context on my situation.
My husband really loves diving but he wasn't doing a heck of a lot of it because I wasn't a diver. So I thought I'd give it a go on a try dive in a pool here in London. I'm very claustrophobic and have the aforementioned deadly fear of sharks.
The dive organisation I signed up with had 4-5 of us in the pool at once with 1-2 instructors. At the end of it they asked how we felt and there was no pressure to sign up for a course or buy anything. I signed up for the OW Referral course, for which you could go as many Tuesday nights (had to be consecutive so you didn't lose knowledge) as it took for you (and them) to feel comfortable with your skills. For me this took three nights with about 3-4 hours in the pool. Most of the other people there were young and female, which surprised me. Again no mention of gear purchase and in fact they recommended against it.
With that we committed to dive trip in Thailand for me to do the OW dives. I was fortunate that I had a great instructor all to myself, and the dive shop was happy for my husband to tag along in the background. The shop did 6 dives instead of the required 4. During one of these I had a bit of a panic in moderately strong waves and had to be tired diver towed back to the boat by the instructor and husband. My dive instructor coached me through what had happened and 90 min later I was back in working on my skills again. Had I not had the instructor and husband to help, I probably would have tossed in the towel at that point. I finished the dives, and went on to complete 10 total in Thailand. The dive shop were just great. It was overall a really great experience and there was never any pressure to prebook, any grief, anything.
We then booked another dive trip to Grenada where I would complete my AOW course. I had a personal recommendation on a shop, and again I got REALLY lucky and had an instructor all to myself for AOW and he would tailor everything to my interests (photography/wrecks). He obviously had time to do whatever I needed, and within a few dives I was down at 30m on an amazing wreck gaping at eagle rays- something I never EVER thought I could do, and I was so happy with myself for handling what the dive shop classified as a "challenging" dive.
We're now looking to book another trip to Indonesia or the Philippines in a few months time. A genuine interest has been created which I hope will lead to a long term passion for diving.
My point in mentioning all of this is that I felt like I was well trained and safe. I didn't feel rushed in ANY way to push myself or to buy anything. In fact my husband has a full set of gear which he never takes anywhere and he prefers to rent. I have a wetsuit, mask, snorkel and computer. I have no intention of buying anything else. I've only been to a dive shop once, and the guy was a complete moron, and almost put me off the whole thing.
I was a reluctant diver, and if I had been pushed through a cattle car program or been told I had to buy $1000+ worth of kit to "try" diving, I NEVER EVER EVER would have considered diving. Feeling in control, looked after, and coached was critical to my moving past the "stressed" phase to the "actually this is fun" phase. Maybe most people don't get this luxury and they don't continue.
Side note on people's fear of sea life: As mentioned above, my team are all alpha male types. They were taking bets on whether or not I'd be fish food. In fact a few of them confessed they freak out when they see a fish in the water at the beach. These are not "soft" emo types but 6'4 big rough men who think I'm a death defying risk taking lunatic. SO yeah, there is probably a perception problem.
Just a newb's perspective.
