Is that TDI? (Your profile is not clear on that.)
My NSS-CDS card has no such notation. If your card has a limit to depth on it, then does the agency have another card that does away with that limit?
Yes, that is TDI. Hence, my view on the meaning of what's written on the card. But if other agencies have limits for some levels and then they disappear for other levels, maybe those limits work in a different way. Probably another thing that should be discussed among agencies.
There are no other cave cards that remove this limit, I think they see deco as a different line of diving progression. And in the standards for full cave they allow deco dives if the diver has at least Deco Procedures or is learning that course at the same time.
