We offer Cavern Diver certification through TDI. A cavern diving certification allows divers to dive with another cavern certified diver in the cavern zone: within the site of daylight, no more than 60 meters from a surface, and avoiding restrictions (tight places).
The course covers everything from laying a guideline to emergency management, and can be conducted in single tanks, back mounted doubles, or side mount. Prerequisites include a minimum of 25 logged dives and an advanced open water certification from a recognized agency.
Divers who have mastered advanced propulsion techniques, such as frog-kicking and back finning can typically complete the course in three days, divers who are interested in learning to cavern dive, but have not yet mastered these techniques, can typically complete the course in five days.
Intro to Cave Certification through TDI allows a diver to cave dive within the following restrictions: mainline navigation only, no restrictions (areas where divers are forced into single file), no decompression, and using a maximum of 1/6 of double tanks for penetration.
Prerequisites include a minimum of 60 logged dives and an advanced open water certification. For divers with experience in double tanks (back mounted) the course generally requires five days to complete.
Divers without experience in doubles should expect to add approximately two days to the course for familiarization with the equipment configuration, and those interested in learning in side mount should plan on adding approximately three days to the course length. Intro to Cave if a prerequisite for the TDI Full Cave Diver certification.
It should be noted that there is a great number of incredible dives to be done in the Yucatan Peninsula at the Intro to Cave Level, and that the course may be done either as a step towards TDI Full Cave Certification, or as a end in itself. The TDI Intro to Cave Certification does not expire. Divers wishing to complete a Full Cave Certification often take time to gain experience at the Intro to Cave Level.
TDI’s Full Cave Diver Certification allows divers to conduct cave divers including complex navigation (jumps, T’s, traverses and circuits) and restrictions and allows penetration to a maximum of 1/3 of the diver’s breathing gas. Prerequisites include a minimum of 100 logged dives and an advanced open water certification.
The course can be done in combination with an TDI’s Intro to Cave Course (9 days) or after Intro to Cave Certification (4-5 days). Divers without experience in backmounted doubles should expect to add 2 days to the course length, and those in new to side mount should expect to add three days to the course length. This is the big daddy of cave certifications, and opens up hundreds, if not thousands of dives to be done in the Yucatan Peninsula.
For certified full cave divers, we offer a range of cave diving specialties including DPV (scooter), stage and multi-stage, (technical cave), side mount, and advanced side mount.
Prerequisites depend upon the course and experience level, but in general a minimum of 25 logged cave dives past after Full Cave Diver certification are required.
