What does a gas-integrated computer provide to divers?

A gas-integrated computer plays a crucial role in the safety and management of scuba diving by providing real-time indications of the remaining gas supply during a dive. This feature allows divers to monitor their air consumption and plan their dive accordingly, ensuring they have adequate gas for their ascent and any potential emergencies. By displaying the current tank pressure, divers can make informed decisions regarding their remaining dive time and adjust their activities to avoid running out of air. This continuous feedback is vital for maintaining safety underwater, particularly when considering factors such as depth, duration, and individual air consumption rates.

The other options, while potentially beneficial in other contexts, do not align with the specific functionality of a gas-integrated computer. For instance, real-time weather updates are handled by different devices or services, and while information on sea life could enhance a dive experience, it is not a primary feature of these computers. Additionally, depth predictions for a dive are typically provided by dive planners or tables, rather than real-time gas management systems.
