Which items are mandatory to carry as a Divemaster during dives?

The mandatory items that a Divemaster should carry during dives include a surface marker buoy, a first aid kit, and a dive computer.

A surface marker buoy is critical for signaling your position at the surface, especially in conditions where visibility is poor or when you're diving in busy areas. It enhances safety by making it easier for boats and other divers to identify where divers are located.

A first aid kit is essential for addressing any potential medical issues that may arise during diving activities. Accidents can happen, and having immediate access to first aid supplies allows for prompt action, which can be vital in emergency situations.

A dive computer is an important tool for monitoring a diver's current depth, bottom time, and decompression status. It helps ensure divers adhere to safe diving practices and avoid the risks associated with decompression sickness.

These items contribute to the safety and well-being of the dive group and are standard safety equipment that reflects responsible dive leadership. Other options, such as carrying a buddy's equipment or personal items like a camera, do not align with the essential safety responsibilities required of a Divemaster during dives.
