What’s the difference between diving in cenotes and diving in the ocean?
Diving in cenotes is different than diving in Ocean. The environment changes, the rules change. For example, it’s not an open water environment, the buddy system doesn’t exist, the kick technique is different, the guide ratio is strictly 4:1 (4 divers /guide), the communication signs change and the “one third air consuming” rule is very important: 1/3 to enter, 1/3 to go out and the other 1/3 kept for any emergency (it’s easy to get lost). That means, the minimum tank pressure to exit cavern zone is 1000 psi or 80 bars. For all these reasons (and many more), for your safety and to protect Cenotes’ formations, the diver, no matter how experienced he is, must pay attention to the guide’s briefing and to his indications underwater!
