What is the role of a dive computer?

The role of a dive computer is to monitor safe dive limits, making it an essential tool for divers. It continuously tracks a diver's depth, time underwater, and ascent rate. This information is crucial for avoiding decompression sickness, also known as "the bends," which can occur when divers ascend too quickly or exceed no-decompression limits.

By calculating the amount of nitrogen absorbed by the body at various depths and durations, the dive computer can recommend safe ascent rates and necessary decompression stops. This ongoing monitoring provides real-time feedback, ensuring that divers remain within safe parameters throughout their dive.

While tracking underwater navigation and predicting environmental conditions are important aspects of diving, they do not encompass the primary function of a dive computer. Enhancing physical training is also unrelated to the specific job a dive computer performs. This technological device's main focus is to support divers in maintaining safety during their underwater excursions.
