My girlfriend's newly minted PADI OW card says "This qualification meets ISO 24801-2: Diver Level 2 -- Autonomous Diver Standard." I had to look it up. Basically it "recommends" that she dive to "20 m" along with other divers of the same certification level. Diver Level 1 recommends that the diver "dive to a recommended maximum depth of 12 m under the direct supervision of a dive leader." I interpret that as probably meaning that, according to PADI, she (Level 2) is qualified to dive deeper than 60 feet or under conditions beyond her training if accompanied by a "dive leader."
