Blue life is a dive operation run by my colleague Frank Gutierrez.
I send people to Frank for cave certification because I know the quality of training he provides, having taken his courses myself.
To become a certified cave diver, you'll do the following courses:
- Cavern Diving
- Introduction to Cave Diving
- Full Cave
Sidemount is the preferred method of diving the Mexican caves, and you will thank yourself for doing a little extra training to become a sidemount diver at the beginning of your cave training.
Discuss equipment purchase with Frank when you are booking. He can do great deals on cave gear.
