NDL = No Decompression Limit. (Going beyond the time allowed on tables or your computer) Definitely dive a cenote with a computer.

Cenotes go from 30 feet or so down to beyond recreational limits. But they can take 45 minutes to navigate. So if you go too deep and your consumption increases accordingly, you might see an issue. Personally I am a heavy breather and usually dive with 100s. But if you are with a good operator/guide and you discuss your air consumption beforehand you shouldn’t have any problem selecting a cenote with a dive profile that suits your skill set and personal limits.
