CCR Trimix Cave Diver
The purpose of the Trimix Cave Diver course is to provide the Cave Diver training for the safe planning and execution of mixed gas diving in caves to depths not exceeding 90 m/300 ft. The diver will be introduced to the proper and safe use of helium as a breathing gas, along with oxygen and nitrox for staged decompression. This course will emphasize precision and accuracy in all aspects of the dive beginning with advanced pre-dive planning. Safety will be a primary focus of this course due to the depths to which dives will be made.

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.
