Both allow 50m with 30min deco.
You are "allowed" to do anything you like: We're not dealing with law here.
Courses TRAIN YOU to do a certain thing in accordance with some published curriculum. They don't "allow you" to do anything.
On a beach dive, you are "allowed" to do anything you choose to do, unless the Fish-Cops demand you show a dive flag from your float (try that for a 190 foot beach dive.. off of Castle Hill here.. ever tow a float in 190 feet of water? Fish-Cops insist it's "The LAW")
On a boat dive you are allowed to do *anything* the Captain choses to let you do. As for this Captain, I'd be far less likely to allow you to dive air to 50 meters in 2 meter visibility on a wreck no matter what your C-Card says, than I would be to allow you to dive that same depth using normoxic trimix no matter what C-Card you carry. One is safer than the other, so which one has a better chance of bring the diver back to the deck safely? That, after all, is the *goal*, isn't it? Yes, I would encourage a diver to seek proper training. Its the definition of "Proper" that's the key here. Don't die, OK?
