What is the recommended buddy proximity during a dive?

The recommended buddy proximity during a dive is to stay within 2 seconds of each other. This practice ensures that divers can quickly come to each other's aid in case of an emergency, such as an equipment malfunction or an unexpected current. Maintaining this close proximity promotes safety, as divers are able to keep visual contact and easily assist one another while monitoring each other's behavior and air consumption. By adhering to this guideline, divers enhance their safety and preparedness for any potential incidents underwater.

The other choices, while suggesting varying degrees of closeness, do not adequately ensure the immediate accessibility needed in emergency situations. Staying within 5 seconds, 10 seconds, or 2 feet can create a distance that may delay assistance and response time if one diver encounters difficulties. Thus, the 2-second rule is emphasized for optimal safety and effective communication between dive buddies throughout the duration of the dive.
