Which piece of equipment is recommended for a diver's safety related to stress management?

The recommended equipment for a diver's safety related to stress management is a dive computer and a signaling device. A dive computer is essential because it provides real-time data about depth, time, and decompression limits, allowing divers to make informed decisions and avoid dangerous situations that can lead to stress. By monitoring their dive profile, divers can manage risks more effectively, reducing anxiety regarding safety and minimizing the likelihood of stress-related incidents underwater.

A signaling device, such as a whistle or surface marker buoy, serves as an important tool for communication, particularly in emergency situations. Being able to signal for help or convey one’s whereabouts can alleviate feelings of isolation or panic, enhancing overall safety and peace of mind during dives.

The other options do not directly focus on stress management. While a larger BCD and additional weights may provide physical comfort and stability, they don't address psychological factors critical for managing stress. A surface buoy and additional fins may enhance safety and mobility but lack the direct impact on stress management that communication and monitoring tools offer. Finally, while a camera can be an enjoyable way to document dives, it does not contribute to a diver's safety or stress management in the same way that the dive computer and signaling device do.
