PADI Divemaster Certification Practice Exam

What equipment should be available at 5 meters/15 feet for deep dive support?

1. Underwater cameras

2. Spare weights

3. Spare cylinder and regulator

4. Emergency oxygen tanks

The correct answer is: Spare cylinder and regulator

The correct choice is spare cylinder and regulator. At a depth of 5 meters (15 feet), a spare cylinder and regulator can provide essential support in the event of an emergency, particularly if a diver experiences a problem with their primary breathing apparatus. The availability of this equipment enables a timely response to potential gas supply issues, allowing divers to safely manage ascent or return to the surface without running out of air. While underwater cameras, spare weights, and emergency oxygen tanks may have their place in diver safety and experience, they do not directly address the immediate need for breathable air that is crucial during deep dives. Cameras, for instance, aid in capturing experiences but offer no critical support in emergencies; spare weights are useful for buoyancy adjustments but do not assist with breathing issues; and while oxygen tanks are beneficial for treatment of certain conditions like decompression sickness, they may not be immediately necessary or useful at this depth for a deep dive scenario. Thus, having a spare cylinder and regulator is fundamentally important for ensuring safety and preparedness during a dive.
