I have to admit to date every buddy I have dove with that I have meet through DiveBuddy.com I would gladly dive with again. I have dove with people that I felt I needed to keep an eye on for their saftey though. I have dove in unfamiliar situations with divemasters on charters that I felt less secure then with new divers with less then a dozen dives. I feel the best quallities are buddies that unprompted aske about air, reg and octo checks, o2 percents, plan, if hunting what is accent or retreat plan, pesty shark aborts, just little things like that build my comfort levels, instead of me being one asking all of the time.
