Hey Byron, I'm an inexperienced diver, and I can only share what I did when I first got certified.I got on a boat and did liveaboard within a week of being certified, and the only gears me and my friend had were mask and snorkel. The crew finished the first briefing with words like "we have two newly certified divers, and they'd appreciate if any of you could let them tag along". So we followed 3-4 couples for the following a few days, and they were pretty cool about it. Basically, we did the liveaboard without a comupter or watch.It might also have something to do with that people tend to be more accommodating with girls
Would you be able to rent a computer? If you couldn't commit now.
