If you were to do just one Navigation dive (there are three in the specialty), you would qualify for AOW. You may want to find an instructor who would do that one dive with you and certify you for AOW.Deep, nitrox, UW photographer, UW naturalist, Fish ID. The instructor on the last deep dive said as far as he was concerned I earned my first boat and salvage dive as well. I was safety diver while he and another instructor salvaged an anchor for a nearby boat - we had to dive out of a very small RIB....overall I already had 71 deep dives, 8 night dives, 147 boat dives though.....
