- Durable construction and reliable materials The hand reel uses ABS and plastic for a strong, durable body, while the reel itself is aluminum with a stainless steel double-ended bolt. This combination provides lightweight performance and corrosion resistance for reliability in a variety of underwater conditions. - Large center hole for easy handling The larger center hole is designed for bare hands or when wearing cold water gloves. A swivel connector helps prevent line tangling and twisting, and the clip easily attaches to the hole for secure setup and quick use. - High visibility line for tracking and safety Includes a nylon line in lengths of 49 feet or 98 feet. The bright orange color stands out underwater, making it easy to spot and track the line during your dive. - Easy to use and operate The curved side design and double-ended clip prevent the line from spinning on the spool when winding, allowing smooth winding on or off. A large reel handle provides easier pulling back of the line. - Practical use scenarios 1) Reef or wreck exploration: deploy and retrieve a retrievable line to mark a path, aid navigation, and ensure quick line recovery in currents. 2) Cold water or glove-heavy diving: the large center hole accommodates gloves, improving handling and setup in chilly conditions. 3) Orientation and safety tethering: use the high-visibility line to maintain orientation and quickly locate the reel during ascent or when working in low-visibility environments.
