4‑in‑1 Remote Cable Tester – RJ45/RJ11/USB/BNC Continuity & Fault Detector with Remote Module

The 4‑in‑1 Remote Cable Tester is a handheld tool designed to verify wiring continuity, detect shorts, open circuits, and crossover wiring in Ethernet (RJ‑45), telephone (RJ‑11), USB, and coaxial (BNC) cables. Featuring gold-plated contacts and support for both shielded (STP) and unshielded (UTP) cables, it delivers reliable and consistent results. A detachable remote module enables testing at both ends—up to 1500 ft or ~460 m—while visual LED indicators and an audible buzzer report test outcomes instantly. The device automatically powers off when idle, saving battery life, and packs neatly into an included carrying pouch for easier portability.
