AOW won't be enough for 'everywhere', NAUI doesn't look at AOW like PADI does, you'll need Rescue to equal AOW in a place that recognizes NAUI such as French Polynesia. Just say'n if you want to be technical.
I have my open water certification with 30+ dives. Just quit my corporate job and have some free time on my hands. Was considering going for my dive master certification somewhere warm. Looked like about 8 week investment and around $2800. Might be doable. But I don't really need the certification and I don't really plan on working in the industry. I just want to do a bunch of diving and keep my costs down. Is it worth it? Or am I better off just going somewhere cheap like Utilla or Thailand for a month?
