PADI does 40m IIRC, with its deep diving components. Other certification organizations are different.

Mauritius had fantastic diving, but the sites tend to start at 25m. I think I saw 60m sites listed among the well know locales, although the deepest my divemasters went the week I was there was 46m (deeper would need more complex decompression stops and multiple tanks for more than a minute or so at the bottom). I think NAUI was the predominant body on the island at the time.

I went down a rabbit hole on this yesterday, and PADI does 40, 45, and 50 meter certifications. Each has the previous one as a prerequisite, plus nitrox and others. Perhaps that's the reason I was told that PADI stands for "Put Another Dollar In".
