Entanglement — What It Is and Why It Matters
Entanglement is a hazard where a diver becomes caught in fishing line, nets, kelp, rope, cable, or other material that restricts movement. Entanglement can escalate quickly if the diver panics and thrashes, wrapping the material tighter. Calm, methodical cutting with a dive knife or line cutter is the standard response.
Prevention involves streamlining your equipment (tucking in dangling hoses, gauges, and accessories), maintaining awareness of your surroundings, and avoiding contact with overhead obstructions. Carrying a cutting device — even a small line cutter — is considered essential safety equipment for any dive environment where entanglement hazards exist.

Frequently Asked Questions
What should I do if I get entangled?
Stop. Do not pull or thrash — this usually makes it worse. Signal your buddy for help. Identify the material and where it is catching. Use your dive knife or line cutter to carefully cut yourself free. If your buddy is helping, stay still and let them work. Maintain controlled breathing throughout.
How do I reduce my entanglement risk?
Streamline everything: clip your SPG and octopus close, tuck your alternate air source into a holder, use short hose configurations, keep your reel line taut during deployment, and do not let gear dangle. Avoid swimming through dense kelp or near fishing line. Carry a cutting device on every dive.
