What should a diver do if they are uncertain about their dive computer's readings?

If a diver is uncertain about their dive computer's readings, referring to a dive guide or buddy is the most appropriate action. A dive computer is an essential tool for monitoring various elements such as depth, time, and no-decompression limits. However, if there is any doubt about its accuracy, consulting with a knowledgeable partner or guide can provide an additional layer of safety. They may have similar equipment and can cross-check readings or even offer a second opinion based on their own experience and training.

Continuing to dive while uncertain does not address the potential safety risks associated with incorrect readings. An immediate ascent without understanding the reason for the discrepancy could also lead to problems, such as decompression sickness if the issue was misjudged and the diver ascends too rapidly. Therefore, seeking clarification and advice from a buddy or guide is a prudent step that ensures safety while effectively resolving uncertainty regarding dive computer readings.
