Full Cave Diver Course
When it comes to cave diving, Mexico offers something for everyone. Whether a novice or experienced cave diver, Mexico has fantastic dive sites perfect for learning new skills and exploring your passion. Suppose you’re interested in becoming a TDI Full Cave Diver and want to explore the option of learning to dive in caves in Mexico. In that case, this blog post will give you all the information you need to get started on your path to becoming a certified cave diver:
There’s so much more to cave diving than just donning a wetsuit and jumping into the water. From technical diving equipment requirements to specialized dive training programs, Divers UnderGround is here for you!
Cave diving is a type of diving that requires technical diving knowledge. It is not something that can or should be attempted by divers without the proper training and certification. The risks of cave diving are significantly higher than those of conventional scuba dives because there is no direct way out of the water in case of an emergency.
There are many different courses and levels of certification when it comes to cave diving.
As with any other type of diving, cave diving requires training and certification from an accredited agency. We are an official TDI Five Star Cave Diving Center and Instructor Training Facility. Diving in Overhead Environments is different from other types of diving, requiring additional equipment and specialized training.
You must follow all diving protocols, monitor your gas levels, keep track of dive time, and conduct regular equipment checks. Awareness of local hazards in the diving area is also essential.
Improperly maintaining your dive gear, not following your training, or failing to equip yourself with the right dive gear for the dive site are some ways you can find yourself in a horror situation in the cave.
Also, it would be best if you dived with a certified and experienced local cave diving guide/instructor who can help you understand the hazards and risks of the dive site.
It is up to you to stay safe and ensure that nothing happens to you inside the cave by following the rules.
Do not enter the water if you do not have the experience and training to do the dives. Stay safe, and do not put yourself and your team in danger.
The TDI Full Cave Diver course teaches you to dive into more navigationally challenging cave systems safely.
During this course, you will learn advanced dive planning, gas management, and navigating complex caves. Also, at this level, you begin to encounter and deal with restricted cave passageways.
The Full Cave Diver course expands your skills and knowledge from the TDI Cavern Diver and the Intro to Cave diver level to prepare you for more complicated dives, including penetrating extensive distances in the cave with tricky navigation and negotiating restricted passages.
Here, you learn how to plan more complex dives and enhance previously known skills to match new and more challenging situations. Greater distances require greater awareness as the physical and psychological challenges increase.
Cave divers can encounter intersections, jumps, gaps, circuits, and traverses. Complex navigation requires clean diving techniques and advanced referencing methods to avoid disorientation.
TDI Full Cave Diver Course
The Technical Diving International (TDI) Full Cave Diver program consists of three sections:
1. Cavern Diver:
TDI designed this course to develop the minimum skills and knowledge for cavern and overhead environment diving within the limits of light penetration; it also outlines specific hazards associated with cave diving. The intention of the cavern diver course is NOT to provide instruction for cave diving environments. This course aims to train divers in the proper planning, procedures, techniques, and cavern diving hazards.
Qualifications limits of Graduates:
1. Cavern diving within the natural light zone of the cavern entrance.
2. Maximum penetration is limited to 1/3 of a single diving cylinder or 1/6th if using double cylinders.
3. 61 linear meters / 200 linear feet from the surface.
4. 40 meters / 130 feet maximum depth.
5. No decompression diving.
6. No restrictions; no areas too small for two divers to pass side-by-side
7. Safety stops as appropriate or necessary.
8. Maintain a continuous guide-line.
9. Use proper cavern diving equipment.
10. Removal of dive gear within the overhead environment is not allowed at this level of training.
Upon completing this program, graduates are qualified to enroll in the TDI Introductory Cave Diver course.
1. Minimum age 18 (15 with parental consent).
2. Provide proof of an Open Water Scuba Diver certification.
3. Minimum of 25 logged dives.
Course Structure and Duration:
At least four cavern dives at two different sites.
The TDI Cavern Diver course takes at least three days to complete.
2. Intro to Cave:
This course is the introduction to the basic principles of cave diving utilizing a single primary guide-line. The TDI Introductory cave diving is the second level in developing safe cave diving techniques, directly building upon the cavern diver course. The intention of this Introduction is NOT to train divers for all facets of cave diving. The Intro to Cave course aims to perfect the Cavern Diving Program’s skills and learn additional techniques and procedures required for elementary cave dives.
Qualification limits of Graduates:
1. Single guide-line cave diving.
2. Maximum penetration is limited to1/3 of a single diving cylinder or 1/6th if using double cylinders.
3. 40 meters / 130 feet maximum depth.
4. No decompression diving.
5. Maintain a continuous guide-line.
6. Student divers must use proper cave diving equipment.
Upon completing this course, graduates are qualified to enroll in the TDI Full Cave Diver course.
1. Minimum age is 18 years old, or 15 with parental consent.
2. Provide proof of certification as a TDI Cavern Diver or equivalent.

1. At least six single guide-line cave dives in two different sites.
1. The TDI Introductory Cave Diver course takes a minimum of 4 days. (Cavern + Intro combined = 5 Days and 8 dives).
3. Full Cave Diver Course:
This course is the third step of training in the series of the TDI’s Cave Diver development program. During this part, you learn Advanced cave dive planning, the practical execution of different types of cave systems, and possible scenarios cave divers can encounter. This course aims to practice and expand previous skills achieved in the TDI Cavern and Introductory Cave Diving programs. We emphasize dive planning and skill perfection through actual complex navigation cave dives and cave
