So if, in the context of your insurance, you were ever asked what you believe the certification limit is of a PADI OW diver, what would you say? I'm guessing you would just play it safe and say all OW certifications are limited to 60 feet, and that's what you would limit a PADI OW diver to on your charters?PADI standards only exists to PADI instructors. They do not publish standards so it isn't possible to be held to something that doesn't exist.
