A lost line drill is a critical training exercise for cave divers to simulate the scenario of losing the primary guide line while inside a cave. This drill helps divers practice essential skills to locate the line and ensure a safe exit.

Steps for Performing a Lost Line Drill

1.-Preparation:
Set up the primary guide line before starting the drill.
Ensure all divers are equipped with proper gear, including reels, safety spools, and backup lights.
Conduct the drill in a controlled environment with an experienced instructor or guide present.

2.-Simulating Line Loss:
The diver closes their eyes or wears a blackout mask to simulate zero visibility.
The diver is placed a short distance away from the main line to simulate disorientation.

3.-Deploy the Safety Spool:
The diver takes out the safety spool or reel and secures it to themselves (e.g., a D-ring) or another fixed point to ensure they maintain reference to their starting position.

4.-Searching for the Line:
Use a systematic search pattern while maintaining physical contact with the spool or reel line.
Sweep the area methodically with one hand while maintaining the spool line taut to avoid entanglement.
Pay attention to the direction of movement and avoid unnecessary motions.

5.-Locating the Primary Line:
Once the primary line is found, confirm it's the correct line by feeling for markers (if used) or checking its characteristics (tension, position, etc.).
Secure the spool line to the primary line to create a reference point.

6.-Exiting the Cave:
Follow the primary line back to the exit, maintaining good buoyancy and situational awareness.

Practice calm and controlled breathing throughout the drill.

Key Points to Remember

Always maintain a good trim and buoyancy to avoid silting out the area further.
Practice team communication and hand signals when performing this as a team drill.
Regularly practice this drill to build confidence and proficiency in real-world scenarios.

This drill is vital for safety and should be practiced under the supervision of a qualified cave diving instructor.
