What should a diver do if separated from their buddy?

If a diver becomes separated from their buddy, it's crucial to follow proper protocol to ensure safety. The recommended action is to search for a minute and then ascend if the buddy cannot be located. This approach is correct because it allows a brief period to reconnect with the buddy while also preparing for safety if the search is unsuccessful. During this initial minute, the diver can scan the area, using any available visibility to look for their buddy and signal them if needed.

Ascending immediately without searching might lead to unnecessary risks, such as becoming disoriented or missing the chance to reunite with the buddy. Signaling for help from other divers is a viable option, but only after assessing the situation for a brief search. Continuing to dive alone can significantly increase the risk of accidents and is not advisable under any circumstance. The combined focus on both searching and safety through ascent is fundamental to good diving practices.
