What is the role of a dive computer?

A dive computer serves a crucial role in ensuring the safety of divers by tracking important variables such as current depth, elapsed time, and no-decompression limits. By continuously calculating nitrogen absorption and providing real-time data, the dive computer helps divers avoid decompression sickness, which can occur if they ascend too quickly or exceed no-decompression limits. It allows for greater flexibility in dive profiles while maintaining safety, as it can adjust to various factors such as variations in depth and breathing gas mixtures. Furthermore, the information provided by a dive computer is essential for planning safe ascents and ensuring that divers adhere to safe diving practices throughout their dive.
