hi, im a new diver who is a bit confused. my open water training said that open water certification qualifies you to go a maximum of 60 feet. but the moment you step out of training & sign up with a 2-tank boat dive with any operator in cozumel, it seems they all do 1 "wall dive" at about 80 feet, and then a shallower dive of 40 to 60 feet. should i be concerned about the fact that i can't get on a dive that will max out at 60 feet all day? or is this just standard safe operation in cozumel? i've gone to 80 feet with the group & not had problems, i don't even feel uncertain about it, but i'm just trying to reconcile the PADI certification training suggestion of "up to 60 feet" with the real-world commercial options that seem to be available in cozumel. many operator websites claim to try to group people by experience, but it doesn't seem like that actually happens. am i missing something / doing something wrong? thanks!
