Extended reach for automotive testing: 3 m or 6 m of flexible testing wire on a long lasting retractable reel enables diagnostics in tight engine bays and hard to reach vehicle components. Secure, ready to use connections: integrated clips on both ends attach firmly to multimeter ports and automotive terminals, simplifying electrical system testing, continuity checks, and voltage measurements during car repairs and maintenance. Compact professional design: lightweight and easy to store, with a spool diameter of 152 mm for the 3 m version or 175 mm for the 6 m version, allowing tidy storage in a toolbag or glove compartment and quick access when needed. Dual port functionality: connection ports on both sides of the reel housing enable simultaneous use at multiple test points or easy switching between measurement functions without repeatedly replugging cables. Specifications and compatibility: available in 3 m or 6 m lengths; retractable reel; lightweight, durable construction; integrated clips at both ends; dual ports on the reel housing for versatile automotive electrical testing. Use scenarios: In a crowded engine bay, reach sensors and wiring without dismantling components to perform voltage checks or continuity tests. During repairs, test multiple segments of a wiring harness or switch between circuits quickly without removing cables. In a workshop, monitor several test points at once or switch measurement functions efficiently while diagnosing electrical issues.
