What is the purpose of using dive markers during a dive?

Using dive markers during a dive plays a crucial role in enhancing visibility and providing navigation points for divers. These markers serve as reference points that can help divers orient themselves underwater, especially in areas where visibility may be compromised due to murky water, sediment, or other factors.

Dive markers are beneficial for several reasons, including directing divers back to specific spots, marking the location of the dive site, or even indicating potential hazards. They can also be useful for buddy teams to stay together and maintain situational awareness about their surroundings.

While other options mention potential uses of dive markers, they either don’t address the primary purpose or represent less critical or relevant uses. Options that suggest distraction or marking the beginning of the dive do not encapsulate their practical application during the actual dive. The primary intention behind using dive markers is fundamentally about improving safety and navigation, which makes this option the most appropriate answer.
