Have opportunity to take SSI Perfect Buoyancy this Friday have set personal goal to get Master Diver by April this year by end of March before trip to Cozumel in April and need two more specialties for total of five already have AOW, Rescue Diver along with three PADI Specialties (Wreck, Dry Suit, & Enriched Air). Don't care which dive agency I get specialties with as long as PADI will recognize them for Master Diver. taking suggestions for other specialty courses I should look at that will make me a better diver. I have 234 logged dives and in the neighborhood of 100-150 dives that I failed to log that were in my Suunto Cobra Dive computer (stuck in perpetual dive mode till battery died) that I failed to log before it died and I cant retrieve dive data.
Here is a simple explanation of the 2 agencies and the requirements from each to earn the Master Scuba Diver Certificaiton.
