If you want to learn to dive yourself safely in overhead environment such as caves and be able to solve the problems that may occur,
these are the courses that make for you!
Different levels for different types of experience.
Courses can be conducted in sidemount or backmount configuration, ask for info
This course is designed to develop the minimum skills and knowledge for cavern and overhead environment diving within the limits of light penetration; in addition outlines specific hazards associated with cave diving.
The cavern diver course in not intended to provide instruction for cave diving environments.
The objective of this course is to train divers in the proper planning, procedures, techniques and hazards of cavern diving.
Four cavern dives with a total bottom time of 80 minutes.
This course is an introduction to the basic principles of cave diving utilizing a single primary guide line.
Introductory cave diving is the second level in the development of safe techniques for cave diving, directly building upon the cavern diver course. This introduction to cave diving is not intended to train divers for all facets of cave diving.
The objective of this course is the perfection of skills taught in the cavern diving program, in addition to the adoption of additional techniques and procedures required for elementary cave dives.
Minimum of 4 single guideline cave dives with a total bottom time of 100 minutes
This course examines the theory, methods and procedures of planned stage decompression diving.
This program is designed as a stand-alone course or it may be taught in conjunction with TDI Advanced Nitrox, Advanced Wreck, or Extended Range Course.
The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 45 metres / 150 feet unless taught in conjunction with the TDI Extended Range Course. The most common equipment requirements, equipment set-up and decompression techniques are presented. Students are permitted to utilize enriched air nitrox (EAN) mixes or oxygen for decompression provided the gas mix is within their current certification level.
8 cave dives are required with a minimum accumulated bottom time of 240 minutes.
The students must have the following personal equipment:
- Adeguate suit (recommended minimum 5 mm)
- Instruments (2 computer or computer + logger)
- Wet notes or wrist slate
- Shears or small knife
We strongly recommend students have their own equipment:
- Back mount or sidemount configuration
- 2 regulators DIR minded
- 1 primary light (at least 1000 lumen up 4 hours burning time)
- 2 back up light
- 2 Safety reels (spool)
This course is designed to teach trained cave divers how to extend bottom
times and/or penetration distance through the use of stage cylinders. Divers
will learn to plan dives that may incorporate longer bottom times, complex
dive planning, and multiple methods of gas management. With respect to
depth, gas mixes, and required decompression, course dives will not exceed
the student’s current level of certification and experience level.
Upon successful completion of this course, graduates may engage in stage
cave diving activities without direct supervision so long as the following
limits are adhered to:
1. Penetration is limited to the 1/3 air rule, or more conservative air-plan at
2. No equipment removal in cave with exception of stage cylinders.
3. Students are encouraged to gain experience before attempting to plan
and execute complex stage cave dives.
4. Safety and decompression stops are completed as appropriate or
Upon successful completion of this course, graduates may engage in DPV cave
diving activities without direct supervision so long as the following limits are
1. If each diver utilizes a single DPV, each diver must turn the dive with no less
than twice the amount of gas required to exit the cave while swimming
2. If each diver utilizes multiple DPVs, each diver must turn the dive with no less
than twice the amount of gas required to exit the cave while utilizing the DPV
3. No equipment removal in cave with exception of stage bottles if utilized
4. 39 metres /130 feet maximum depth
5. Students are encouraged to gain experience before attempting to plan and
execute complex DPV cave dives
6. Safety and decompression stops are completed as appropriate or necessary
