Avoiding Entanglement: Staying Clear Underwater

Entanglement can arise from various sources in the underwater environment, from fishing lines and nets to mooring lines, kelp forests, or even poorly stowed dive gear. While less common in well-maintained recreational dive sites, derelict fishing gear (ghost gear) poses a significant and ongoing threat globally. Understanding where and when these risks are prevalent is the first step in prevention.

Factors such as strong currents, low visibility, night diving, and diving in areas known for marine vegetation or human activity (like shipping lanes or fishing grounds) amplify the potential for entanglement. Divers should always assess the site conditions and potential hazards during dive planning, consulting with local dive operators and instructors for site-specific advice.

Effective prevention begins before you even enter the water. Equipment configuration is crucial; ensure all hoses, gauges, and accessories are neatly routed and clipped close to your body. Avoid dangling equipment that can easily snag. Manufacturers often provide guidance on optimal hose routing for their specific BCDs and regulators, which should be followed diligently. Carrying a sharp cutting tool, such as a dive knife or line cutter, is essential, but it must be easily accessible with either hand.

Buoyancy control is perhaps the single most important skill for entanglement avoidance. Maintaining neutral buoyancy allows you to stay clear of the bottom and delicate marine life, as well as potential snag hazards. Proper trim, enabling a horizontal swimming posture, further reduces the chance of dragging equipment. Regular practice of these skills, as emphasized by all reputable training agencies, is fundamental.

Should an entanglement occur, the primary directive is to remain calm. Panicking will only exacerbate the situation, consume air rapidly, and impair clear thinking. Signal your buddy immediately. Most entanglement incidents can be resolved with a calm, methodical approach and the use of a cutting tool. Remember the 'Stop, Think, Act' principle taught by many agencies.

If self-extraction proves difficult or impossible, your buddy should assist. It is vital that both divers are trained in buddy rescue and entanglement procedures. If you find yourself in a situation beyond your training or comfort, ascend slowly while maintaining control, if possible, or signal for surface support. Defer to the advice of dive medical professionals for any post-incident assessment, especially if stress or injury occurred.
