Cave Diver

This course is designed for divers who already possess their Cavern Diver and Intro to Cave Diver certifications. It can be taught as a package with those courses or as a stand-alone addition for divers already certified in the prerequisites. You can do this course in sidemount or Backmount. All training is conducted in the cenotes of Tulum or Playa Del Carmen.

In this course divers learn about navigation inside the cave. The Quintana Roo is home to some of the most complex caves in the world. We teach you techniques that allow you to dive confidently. Divers will also learn to pass through minor restrictions independently whilst in single file formation, as well as whilst sharing gas and in touch-contact with a dive buddy during a simulated zero visibility drill. Divers will venture deeper into the cave, using the full rule of thirds to maintain adequate gas supply, should an out of gas emergency arise. Divers learn about the unique psychological challenges of diving in an overhead environment and how “distance stress” can present the farther the diver is from the cave entrance.

Our team of international instructors and explorers have been diving in caves all over the world including; Mexico, France, Italy, Madagascar, Bahamas, Florida, Dominican Republic, Australia, Haiti, Austria, Belize and many more locations. Being exposed to so many different conditions in underwater caves, our team can condense years of knowledge and experience into your class, making you a more rounded cave diver that is equipped for diving all types of caves and conditions.

With an average depth of 9m (30ft) – 12m (40ft) the caves of Mexico are the perfect place to hone your skills as a Cave Diver in sidemount configuration or backmount configuration. Considering this and the fact we will be using a more aggressive gas rule, you can expect for some much longer dives during this section of your training. Once we leave the mainline and venture off into the labyrinth of cave passages found throughout the area, we will expose you to new problems that might arise and give you the tools you need to work through these problems, and many more, in a safe and controlled setting.

Certification for this course is offered through PSAI Mexico. This course takes a minimum of 4 days to complete and is available to all Intro To Cave Divers or those with an equivalent certification. Alternatively, it can be combined with the Cavern Diver and Intro To Cave class for 9 days of training.
