PADI Divemaster Certification 2026 – 400 Free Practice Questions to Pass the Exam

A dive computer is designed to assist divers by providing real-time information crucial for safe diving practices. Among the aspects typically tracked by a dive computer are dive time, current depth, and ascent rate. These parameters help divers manage their dive profile safely, ensuring they stay within acceptable limits of exposure and ascension to avoid decompression sickness.

Heart rate, however, is not a standard feature tracked by most dive computers. While some advanced dive computers may have capabilities to integrate with additional sensors that monitor heart rate, it is not a core function of dive computers in general. The primary focus of these devices is on tracking the diver's environment related to pressure and time, which are vital for ensuring safe ascent rates and compliance with no-decompression limits.

Therefore, the aspect that is not typically tracked by a dive computer during a dive is heart rate, as it falls outside the primary function of monitoring underwater parameters relevant to dive safety.
