8strand nylon weave for strong, durable use The 8strand nylon construction provides strength and long service life. It is safeguarded against oxidation and degradation to maintain consistent underwater performance. Smooth, lowfriction wire feeding Pure copper wire feeder glides with minimal friction, helping to keep wire tension steady over a 46 m run. The design minimizes kinks and twists for reliable line deployment. Accurate spool control for controlled descents The pressrelease mechanism locks the wire at the desired length. This enables controlled descents during scuba or snorkeling excursions. Thumbcontrolled depth adjustment A patented thumb stopper allows quick line locking with 360degree rotation. Depth adjustments can be made singlehandedly even when wearing thick gloves. Key specifications and attributes Material: 8strand nylon weave for thread construction; copper for the wire feeder. Length: 46 m dive length supported by the system. Function: Locking spool mechanism for setting and maintaining precise line length; smooth feeding to reduce tangling. Compatibility: Suitable for use with scuba and snorkeling activities requiring controlled line deployment and depth management. Practical use scenarios Scuba descent control: Preset the line to a chosen length, then descend with a steady, maintainable depth using one hand. Snorkeling and reef exploration: Maintain position and depth at a point of interest; adjust depth quickly without removing gloves. Underwater photography or inspection: Keep a stable depth while moving along a subject, with reliable line locking and tension control.
