Required Skill Performance and Graduation Requirements
The following land drills must be covered during this course:
1. Land drills may be performed at the instructor’s discretion
Pre-dive drills 1. 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)
2. Stress analysis and mitigation
The student must perform the following in-water skills during dives:
1. Demonstrate various propulsion techniques: frog kick, modified frog kick, modified flutter kick, backward kick, helicopter turns, and hand pulling if appropriate for the environment
2. Demonstrate adequate buoyancy control; ability to hover at a fixed position in the water column without moving hands or feet
3. Demonstrate adequate trim; ability to maintain proper position during the descent, bottom, and ascent portion of the dive
4. 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 Version 0123 55TDI Standards and Procedures Part 2: TDI Diver Standards
5. Demonstrate the ability to manage gas in independent cylinders safely
6. Demonstrate conservation, awareness, and back referencing techniques
7. Deploy lift bag
8. Carry additional cylinder(s);
optional To complete this course, students must:
1. Perform all land drills and dive requirements safely and efficiently
2. Demonstrate mature, sound judgment concerning dive planning and execution
3. Maintain an appropriate level of awareness and respect for the environment
4. Log all dives
