What types of underwater hazards should divers actively avoid?

Divers should actively avoid entanglement hazards, marine life, and currents because these factors can significantly affect their safety underwater.

Entanglement hazards, such as fishing lines, nets, or underwater structures, pose a risk of trapping a diver, which can lead to panic and potentially serious injury or drowning. Being cautious around these types of hazards is essential for ensuring a safe diving experience.

Certain marine life can also present dangers, whether through bites, stings, or defensive behaviors. Understanding and recognizing potentially harmful species helps divers to maintain a safe distance and avoid any aggressive encounters.

Currents can drastically alter the dynamics of a dive. Strong currents can lead to disorientation, difficulty returning to the entry point, and excessive physical exertion, which can quickly lead to exhaustion. Divers must be aware of the current conditions and plan their dive accordingly to avoid being swept away or getting into difficult situations.

In contrast, weather changes and tides, coral reefs and underwater plants, as well as other divers and swimming classes, can present challenges but are often manageable with proper training, awareness, and planning. While they should be considered, they do not pose the same immediate personal safety threat as entanglement hazards, dangerous marine life, and strong currents. Thus, focusing
