Ultra-elastic 1 meter safety line with stainless steel core - Benefits: stretchable up to about 1 m, built-in six-strand stainless steel wire, and a PU coating provide a strong, durable tether that prevents gear loss and keeps essentials within reach. Anti-loss D-shaped buckle allows secure attachment to your buoyancy compensator (BC) for quick access and tidy storage. - Material and build: crafted from high-grade 316 stainless steel for high strength, excellent corrosion resistance in seawater, and long-lasting performance. - Design and function: one end features a secure hook; the other end a robust screw closure to attach to gear and to keep the diver anchored to the safety line during movement. - Underwater performance: built to handle currents with a reliable stainless steel current hook that provides solid grip and stability, freeing both hands for underwater photography and observation. Suitable for cave diving, sport diving, and underwater imaging. - Applications and scenarios: - Cave diving in strong or unpredictable currents for secure line management. - Drift/open-water dives where hands-free operation is advantageous. - Underwater photography or reconnaissance where a stable, secure tether enhances safety and efficiency.
