activities without direct supervision so long as the following limits are adhered to:
- Penetration is limited to the (1/3) air rule
- Forty (40) msw / one hundred thirty (130) fsw maximum depth.
- Safety and decompression stops as appropriate or necessary.
- Maintain a continuous guideline.
- Proper cave diving equipment is used.
- Planned dives do not exceed diver’s current certification level.
- Be a minimum age of eighteen (18).
- Have a minimum certification of TDI Full Cave Diver or equivalent.

- Course must be taught over a minimum of two (2) days.
The following material is required:
- Instructors may use any text or materials that they feel help present these topics.
The following equipment is required for each student:
- Dual cylinders, volume appropriate for planned dive, and student gas consumption.
- Two independent first and second stage regulators each with a submersible pressure gauge.
- Buoyancy compensator with power inflator appropriate for sidemount configuration.

Required Skill Performance and Graduation Requirements
The following land drills must be covered during this course:
- Land drills may be performed at the instructor’s discretion.
- Use START before every dive
*START is an acronym for S-drill (Out of Gas drill and Bubble Check), Team (buddy equipment
checks), Air (gas matching), Route (entry/exit and planned path underwater, Tables (depth,
duration, waypoints and schedule)
- Stress analysis and mitigation
The student must perform the following in-water skills during cave dives:
- Demonstrate no-silting propulsion techniques (frog kick, modified frog kick, modified flutter
kick, backwards kick, helicopter turns, and hand pulling if appropriate for the environment)
- Demonstrate adequate buoyancy control (ability to hover at fixed position in water column
without moving hands or feet)
- Demonstrate adequate trim (ability to maintain proper position during the descent, bottom
and ascent portion of the dive)
- Demonstrate the ability to perform the following exercises while maintaining trim and
buoyancy in the water column:
A. Unclipping and attaching sidemount cylinders.
B. Perform gas switches with and without a mask.
- Demonstrate the ability to safely manage gas in independent cylinders.
- Demonstrate conservation, awareness, and back referencing techniques
