What are the components of the Information System?

The components of the Information System in diving are focused on providing divers with accurate and essential data during their dives. The dive computer is a critical part of this system as it calculates real-time information such as depth, dive time, and no-decompression limits, allowing divers to make informed decisions about their dive plans and safety. Analogue instruments, like traditional depth and pressure gauges, serve as essential backups to the computer, ensuring that divers can monitor their essential metrics even in case of computer failure.

Additionally, SSI Total DiveLog is a digital logbook that helps divers track their dive history, conditions of each dive, and any observations made underwater. This comprehensive approach to managing data ensures that divers can maintain safety and enhance their diving experiences through disciplined logging and monitoring of their dives.

In contrast, the other options consist of tools and devices that, while useful in the context of diving, do not comprise the core of the information system designed for monitoring and managing dive parameters. Depth and pressure gauges are part of analogue instruments and therefore do not evoke the complete picture provided by the full information system. Similarly, while a compass, watch, underwater camera, and notebook can enhance a diving experience, they do not serve the same primary function as the combined components that provide critical
