Circuit tracer: Trace wires hidden inside bundles, conduits, or upholstery with ease. Enables locating circuits without invasive access and serves as a circuit breaker tracer to help identify the correct circuit quickly. Electrical tester: Flexible probes reach wires in congested places and hardtoreach areas. Facilitates safe testing and verification of wiring and circuit conditions in tight spaces. Cable tester: Quickly identify broken wires and current leaks. Useful for diagnosing cable faults and, in automotive applications, acts as a car short/open finder to locate faults in harnesses and cables. Car wire finder: Designed for car electrical work. Use across a connector, in series with an open wire, in place of a blown fuse, or with a light bulb socket to verify circuit integrity and locate faults in the vehicle electrical system. Key benefits and attributes Allinone functionality: Combines circuit tracing, electrical testing, and cable/auto wiring diagnosis to streamline troubleshooting. Broad compatibility: Suitable for wiring in home environments (bundles, conduits, upholstery) and for automotive electrical systems. Compact and portable: Handheld design optimized for use in tight spaces and on the go. Practical performance: Flexible probes and probing capability enable testing and tracing in hardtoreach areas while delivering reliable results. 23 practical use scenarios Home electrical work: Before remodeling or opening walls, trace the correct circuit behind studs or upholstery to avoid cutting into misplaced lines. Automotive diagnostics: When an intermittent or unexpected electrical issue occurs, locate shorts or open circuits in wiring harnesses by tracing connections and testing across connectors and fuses. Cable and harness maintenance: Inspect long cable runs and automotive wiring harnesses for continuity and leakage, ensuring each segment is fault during installation or projects.
