PADI Divemaster Certification Practice Exam

What should you monitor when supervising a deep dive?

1. Weather conditions only

2. Surface signals only

3. Diver experience, depth, and time

4. Only air supply

The correct answer is: Diver experience, depth, and time

When supervising a deep dive, it is crucial to monitor diver experience, depth, and time because these factors directly affect diver safety and dive planning. Diver experience determines their ability to handle various situations underwater, and knowing their level helps you provide appropriate guidance and support. Monitoring depth is vital, as deeper dives increase the risks of narcosis and decompression sickness. Ensuring that divers adhere to the planned depth limits is essential for safety. Time management is equally important. It helps prevent situations where divers exceed their no-decompression limits and allows for proper ascent rates to avoid the dangers associated with rapid ascents. Tracking dive time also facilitates adequate planning for safety stops and overall dive safety. While elements such as weather conditions, surface signals, and air supply play an important role in dive safety, they do not encompass the comprehensive monitoring needed during a deep dive as effectively as the triad of diver experience, depth, and time.
