When should a diver utilize a dive float or marker buoy?

Using a dive float or marker buoy is important primarily for increased visibility and marking location. When divers deploy a buoy, it helps indicate their position on the surface to other boats and divers, enhancing safety and reducing the risk of accidents. Additionally, it serves as a visual reference for the divers underwater, allowing them to navigate back to their entry point or signal their location to others.

This practice is not limited to diving in shallow waters, as it can be beneficial in a variety of depths. While signaling for help is also a valid reason to use a buoy, it is not the primary purpose for deploying one during a dive. Moreover, deploying a buoy is not exclusively necessary during night dives; daytime use is equally important for safety and navigation purposes. Therefore, utilizing a dive float or marker buoy is crucial for visibility and location marking, ensuring a safer diving experience.
