Before signing up for a TDI Cave Diving course, divers with no previous technical diving experience should consider enrolling in one of the following:
- TDI Intro to Tech diver course when you want to learn cave diving using double back mount tanks
- TDI Sidemount Diver course if you prefer the comfort of diving with two independent single tanks mounted on the side.
TDI Cavern Diver
The Cavern Diver course is the first step towards the Full Cave Diver certification and is probably the most challenging of all three courses. It is here where the diver learns all the basic emergency handling protocols for overhead environments diving.
All three courses are divided into different sections:
Briefings and Debriefings
In Water Drills
Some of the skills introduced in this level are:
Selection and preparation of equipment
Gas matching procedures
Demonstrate familiarity with basic hand and light signals
Proper touch contact communication while following a guideline
Adequate pre dive planning
Deployment and retrieval of a guideline
Gas sharing protocols
Pre dive safety checks to include:
Dive plan review
In water drills:
Proper anti silting and propulsion techniques
Ability to perform the following exercises while maintaining adequate buoyancy and trim:
- Use of light and hand signals
- Proper deployment of a guideline
- Adequate line following procedures
- Touch contact communication while following a guideline
- Gas sharing with and without visibility using touch contact
- Properly remove and replace mask without losing contact with the guideline
- Primary light failure simulation and backup light deployment
- Perform valve shut down drills
- Safety Drills
Demonstrate conservacion, awareness and back referencing techniques
The Cavern Diver course takes a minimum of three days and four cavern dives when taken separately
TDI Intro to Cave
This course introduces the basic principles of cave diving using a single guide line. This is the second step towards becoming a Full Cave diver and further develops techniques, building directly upon the TDI cavern diver course. The intro to cave objective is to fine tune the skills learnt in the cavern diving course and to introduce the additional techniques and procedures required for simple cave diving.
The course follows the same structure as the Cavern Diver course which includes, briefings and debriefings, land drills, predive drills and in water drills. All the skills of the Cavern course are practiced and perfected and the line recovery and lost diver protocols are introduced as well as line entanglement, line cutting and repair.
This course takes a minimum of 4 days when taken separately if already certified as Cavern Diver and it takes a minimum of 5 days if combined with the TDI Cavern Diver course.
TDI Full Cave Diver
This is the last step to get certified as a TDI Full Cave Diver. At this level, advanced cave diving planning for complex navigation and execution of different types of cave diving scenarios are introduced. This course expands the previously learnt skills and emphasises in dive planning and skill perfection through actual cave diving penetration.
During this course the students learn about properly marking their exit lines as they encounter multiple points of navigation and learn to safely plan dives to complete simple and complex circuits and traverses.
The duration of this course when taken on its own and the student is already certified as Intro to Cave diver is a minimum of 5 days. The skills learnt in the Cavern and Intro to Cave course are reviewed before going into the complex navigation portion of the course.
When the course is taken in one shot starting with Cavern all the way to Full Cave, it can be accomplished in a minimum of 8 days.
The Sidemount Diver course is recommended before starting with cave diving training and it adds 2 days at the beginning of the full cave course.
