It’s more for finding the cable pathway, but could help find a dead short. **Q: Can this unit trace wires that are in flex?** A: Yes **Q: Can I trace from a light fixture back to a switch? (I can not find how to turn on a few lights in my new house)** A: this tracer work's better on energized circuits but will also work with de-energized circuits. if your light is not energized, then hook up the transmitter to it and then use the receiver to follow the wire through walls and ceilings to find your switch. You may have to set the detection level higher on the receiver for this use. **Q: Will this tracer generate an audible tone when connected to 14/2 speaker wire?** A: Don’t know. I’m deaf and just look at the visual readout. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***D on 22 January 2026* احنا شركة لصيانة مضخات المياه و التحلية الجهاز ممتاز لتتبع الاسلاك القديمة ### ⭐⭐⭐⭐⭐ Review *by C***. on 25 January 2026* An amazing tool, it saved me a fortune on electricians. ### ⭐⭐⭐⭐⭐ Review *by C***M on 8 February 2024* Lo compre porque requiero un equipo que sea capaz de detectar y rastrear cables enterrados o en paredes, ademas de poder rastrear interruptores. Encontre este equipo, que si bien se puede utilizar para cosas caseras, por su precio y sensibilidad es mas bien para condiciones y trabajos comerciales o industriales. La sensibilidad es ajustable, pues como el generador de señal es muy potente, la señal puede difuminarse en interruptores o zonas adyacentes, pero para eso tiene un metodo de conexion que permite eliminar ligeramente la amplia distribucion de señal. El equipo se ve, se siente y tiene funciones avanzadas, es muy robusto, grande y a la vez facil de utilizar. Viene con varios accesorios para conectar el generador de señal a diferentes necesidades y su instructivo de uso es muy sencillo en caso que no hayas utilizado algun equipo similar. Lo que mas me gusto es que la potencia de señal es muy fuerte, tanto que pude rastrear cables hasta unos 50 cm de distancia y en otras condiciones hasta casi 1 metro. Lo que me gusto tambien es su robustes, es de uso rudo y de uso sencillo. Lo que no me gusto es la gran cantidad de baterias que utiliza, aunque lo usare con baterias recargables, viene con 10 baterias 2AA incluidas. Lo que no me gusto es que la sensibilidad sea ajustable manualmente y no de forma automatica segun se vaya acercando o alejando del rastreo objetivo. Pero en terminos generales estoy muy satisfecho con este equipo y definitivamente lo recomiendo. ## Frequently Bought Together - Klein Tools ET450 Advanced Circuit Breaker Finder and Wire Tracer Kit for Energized and Non-Energized Breakers, Fuses, and Wires - Klein Tools RT390 Circuit Analyzer with Large LCD, Identifies Wiring Faults, GFCI and AFCI Tester, Voltage Drop, Displays Trip Time - Klein Tools 69411 Circuit Breaker Finder Accessory Kit, Circuit Breaker Leads and Adapters --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/646700923-klein-tools-advanced-circuit-breaker-finder-and-wire-tracer-kit](https://www.desertcart.sk/products/646700923-klein-tools-advanced-circuit-breaker-finder-and-wire-tracer-kit) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-23*
