Extech TG20 Wire Tracer Kit and Tone Generator, Cable Locator

Great job and works well, brought for tracing the wires in my motor home and it works.

I was pleasantly surprised how good this purchase was ,it’s accurate and easy to use

At first I was not terribly impressed, thought I had wasted my money. However a few months down the line and it went from waste of money to being gold plated and fantastic. A real life saver. I am an gas engine engineer and had to trace 2 core wire out of a electrical control cabinet in a bundle of 15 wires, down conduit, where it then split into 4 different conduit going all over the engine, we are talking a 30ft x 10ft x 8ft (LxHxW) engine all cable tied together. An impossible task, but this little cheap plastic green tone generator did it, I was so thankful. I would not have been able to do it without this. I identified the cable, checked continuity and it was spot on. Fantastic. I can’t praise this enough today, it has earned its place in my van and it’s now a valuable bit of kit for electrical fault finding and tracing wires

Works reall well. Enabled me to trace a broken wire joint very quickly. Probably rarely needed but invalueable when it is. The tone makes it easy to track wire paths within walls.

Tried this on a job,it does not give you a clear identification tone of correct cable,the signal tone is very weak and inconsistent it comes and goes, changed batteries just in case,same bad result. Do not buy

Works well and has lasted

Good cheap tool

Works well the minus 1 star is because it arrived with two batteries in original packaging but they were both empty so I had to go buy new batteries straight away that than makes the product more expensive as it's sold practically without batteries.

j'ai récupéré le colis en locker ce soir, mais le contenant était un papier souple et le blister est abimé (fendu et troué), en espérant que l'appareil soit intact. je le testerai le week-end prochain et complèterai alors mon commentaire J'ai pu testé ce TG20, c'est impeccable, détection à 80 cm sans obstacle avec le volume fort et en volume faible bonne précision entre 2 câbles d'un faisceau. il est simple, pas de détection lumineuse, seule une sonorité double, mais c'est efficace, de plus son prix est correct et livré avec des piles en plus. Je plébiscite donc ce TG20.

Me ha funcionado a la perfección puedo realizar localización de nodos de red sin mucho esfuerzo, ampliamente recomendado para gente de redes e informatica

I had a problem where there was unusual wiring feeding into a box of light switches. A 14/3 cable (typically used for 3-way light switches) was wired to two different switches at the box - red traveller was connected to one switch, black to another switch. The switch with the black wire also had a burn mark on a terminal. Since I did not know the state of the wiring, I needed a way to diagnose and trace where these cables were running. The Extech TG20 did the trick. With it I was able to trace signal of the red traveller through my joists and drywall to my pendant lights (the signal was actually on a black wire on the pendant... which means I have a hidden junction somewhere in my ceiling), while the black went to the fixture above the dining table. I was able to put the wiring all back knowing what is happening and that there wasn't going to be a hazard. I have since used the TG20 to test a lightbulb, a lamp switch, and terminals on a 12V transformer. Other tools being sold on Amazon included features I didn't need (which could break), and those products seemed to have reliability issues too. Pleasantly surprised the Extech TG20 is made by FLIR (says on the package) which I didn't know prior to purchasing. Nice bonus. TIP 1: To trace a single wire, clip to wire and clip to a grounded wire and not the device box. The tone when clipped to the ground wire is much stronger than if clipped to the box. TIP 2: TURN OFF the main power before doing any work. You do not want to connect anything to live wires. If you are tracing wires through your electrical panel, you want your branch circuits ON but your main service OFF. TIP 3: Connect the TG20 to a foot of cable and play "Find the TG20" with the kids.
