Cave DPV Diver

Students must possess Advanced Open Water Diver and entry-level Nitrox Diver or equivalent certifications from a widely recognized diver training organization, or equivalent experience. This training may take place concurrently with the CDS Basics orientation or Apprentice Cave.

Students participating in any training program involving planned decompression must possess appropriate certification from a widely recognized diver training organization. This training must cover:  Use of pure oxygen or oxygen-rich decompression mixtures and procedures for decompression diving. This training may take place concurrently with NSS-CDS Cave Diver training.

Additionally, NSS-CDS Cave Diver level of training or equivalent and at least 50 logged cave dives beyond the Cave Diver level (not including training dives) is required. Instructors must screen and evaluate students to ensure they possess the necessary attitude, knowledge and skills before any further in-water training takes place. Instructors must refer students who cannot pass this screening process to opportunities where they can obtain remedial training. Only when students can pass the screening process may they continue their cavern/cave training.

Important Information:

Plan carfully your trip to minimize your enviromental impact, please avoid sunscreen / mosquito repellent or other skin products for all water activities. Whenever possible, choose rechargable batteries and aviod to carring things like disposable razors, plastic bags, plastic water bottels, etc. We are in a very fragil and pristine enviroment and is our responsability to keep it that way.

Cave diving is a highly demanding activity with a specific mindset and requeires very good trim, buoyancy, propulsion and awareness. We will do our best to improve your skills and knowledge, also we will set the best training plan according to the skills and experience of each diver to help them to succed in the course, but consider some times we need extra days to achive the goals with a classroom or water sessions and we apply extra rate if is necessary. We strongly recommend to the studens plan at least two extra days just in case.

Notes:

Please bring change of clothes & towels for cenote training days.
