KOLSOL F02 Underground Cable Locator, F02 Wire Tracer with Earphones for Locating Wires and Cables, Pet Fencing Cable Tester, Up to 2-3 Feet Depth and 1000 Feet in Length

This gadget is a fraction of the cost of even hiring a professional cable finder but for most of us will do all we need. The instructions could be better but just as some of the reviews say - After playing with it for a short while u learn how to use it. - Great tool

I got this to find a break in a buried automower wire.My unit did come with instructions and 2 9 volt batteries.I followed the instructions and I can find the wire easily enough but when I got to what I thought was a break in the wire I found that the wire was intact!It seems to me that the receiver is susceptible to interference and changes in depth of the wire.Also the distance from the transmitter seems to effect the signal strength.So I am going to try and use this some more to see if I can improve my technique but for now I am disappointed.

Previously I was using an AM radio to detect breaks in the perimeter wire which worked a few times but it was hard to locate other times. I used this product instead and I found 2 breaks in the perimeter wire and guide wire instantly. Highly recommended!

I tried for several hours. Sometimes I got a "null" signal when I was above the wire, sometimes I didn't. It was far, far from clear. There was sufficient variation in tone even in places without a wire at all that I could have dug up half the garden with false positives. Useless for me.

Easy to trace buried perimeter wires and to pinpoint underground breaks. Looks fairly cheaply made but does the job for a fraction of the cost of professional tools.

Had a break in my robotic mower cable. This gave a signal the whole way round my large garden (despite no continuity when tested). Tried reducing sensitivity but it simply gave whole series of false readings.

Detected broken underground cable on my robotic mower in minutes. Easy to operate. This a really useful addition to my tool box

Signal generator - one lead on the boundary line, one in earth, then simple walk around with the receiver to find the break.I went from both ends and found the break within about 30cm so minimal wire to lift and repair.Good machine.

Je l'ai utilisé pour trouver le cheminement et les ruptures de continuité électriques de câbles enterrés, notamment les fils de guidages de robots tondeuses, mais aussi le cheminement enterré du câble ADSL enterré en vue du passage de la fibre.De grands services pour un prix modique.

Geprobeerd een kabel te vinden. Helaas totaal geen succes

Lo compré para tratar de localizar la toma de tierra general de mi casa (unifamiliar ) y el recorrido de los cable de alimentación de una puerta corredera de entrada de la casa al garaje. Esta alimentación tenía fugas a tierra y de forma intermitente me hacía saltar el disyuntor diferencial de protección.En un registro de conexiones eléctricas en el garaje sale un tubo corrugado con un cable de tierra de 16 mm2 (toma de tierra de la casa) y dos cables (fase y neutro). Estos últimos se dirigen hacia el controlador del motor de la puerta que da a la calle. El cable de tierra se separa en un punto que me era desconocido para hacer la conexión a una pica enterrada en el terreno cuya situación también me era desconocida.Parece ser que los instaladores de la puerta utilizaron la canalización (tubo corrugado) existente para la tierra para poder acceder al interior de la vivienda y alimentar el controlador de la puerta.Puesto en faena, conecté el transmisor entre uno de los dos cables de alimentación al controlador (desconectado tanto en el registro del garaje como en el controlador) y una toma provisional de tierra que hice para este propósito enterrando una varilla de acero de unos 30 cm de longitud en el césped que hay por esa zona.Con el receptor me fui moviendo desde la puerta hacia el garaje siguiendo el "nulo" que se observa cuando la sonda se encuentra justo encima del cable enterrado. Tras unos 5 o 6 metros, se perdió el nulo pero sí que se escuchaba el pitido. En este punto, ya sobre césped, decidí cavar y encontré los dos cables del motor y el cable de tierra. Este último se dirigía hacia su pica en otra dirección.Mientras el cable que seguía no iba junto al de tierra, el nulo era claro. A partir del punto en que se reúnen con el de tierra, el nulo no se observa, sólo el pitido. La operación me permitió sustituir el cable con fugas y solucionar el problema.El aparato ha cumplido la misión para la que lo compré. He de decir que su construcción no es tan robusta como la de medidores profesionales, pero es más que adecuada para un uso ocasional.

I was a little skeptical when I bought this product; I didn't know if this was any good for finding underground cables, but it turned out it was! I did my tracing by connecting the live wire of the cable (power is turned off) to the red alligator clip and putting the black alligator clip on a thin wire that was long enough for me to reach the ground. This way, I could connect the wire to a screwdriver and poke it in the ground. I first tried just connecting the black alligator clip to the neutral conductor, but those results were worse than with the screwdriver in the ground.The signal didn't diminish that much after ±20 meter of wire, even though the soil was pretty solid and the cable was buried ±30 cm underground. I needed to get used to the system at first; don't just swish the antenna back and forth because this may give false results. Instead, gently sweep the ground and hear for a strong signal going into a weak signal (= a sign that you're right on top of the cable) going back into a strong signal on the other side of the cable.Eventually, I found out that I had a break underground. I first thought that the tester was faulty because I didn't get good readings, but after some digging, it was clear that the tester was working like a charm.You do sometimes get some hiccups (weird horror-like sounds when you crank up the volume of the receiver too much) and you have to take your time to get good measurements, but this is definitely useful for outdoor cable tracing!

Fait mieux qu'une radio AM, mais il faut quand même s'y reprendre à plusieurs fois pour localiser la coupure.
