View on AmazonPrice and availability are shown on Amazon and can change at any time.
A transmitter and receiver kit for tracing buried and hidden cable, quoting up to 1000 ft of tracking along a conductor and up to 3 ft of depth in open damp ground, with alligator clip leads, a built in flashlight, a headphone jack, a 1 to 30 V polarity test on the transmitter and a rechargeable battery. What sets the page apart is how much it admits: the depth figure comes with its conditions attached, conduit is named as the thing that halves it, multi core cable is ruled out, and the instrument is stated to work on de energised wire only.
Non energised only is the line that decides the purchase
Buried in the third bullet, before the part about single and dual core cable, is the sentence that determines whether this is the right tool: designed for locating non energized wires only.
That is not a limitation the instrument could avoid, because of how it works. A tracer of this kind puts its own signal onto the conductor at the transmitter and then hunts for that signal with the receiver. The conductor has to be accessible, disconnected and dead for the clips to go on it, and a live mains conductor is neither safe nor quiet enough for the method.
So the job list is specific. Irrigation and sprinkler valve wiring. Invisible pet fence loops. Bell wire, alarm cable, thermostat runs and communication cable. Dead circuits in a wall where you need to know the route before cutting. Buried feeds to an outbuilding that have been isolated at the board.
And the job list it is not for is equally specific: identifying which breaker feeds a live socket, confirming a circuit is dead, or tracing an energised feed through a floor. Those need an instrument designed and rated for live work. Our comparison of circuit tracers separates the two families, because the listings often do not.
A thousand feet along the wire, three feet down, and only in mud
Two range figures are published and they measure different directions.
1000 ft, stated as 305 m, is distance along the conductor. That is how far from the transmitter you can still pick the signal up as you follow the run, and it is a generous figure for a garden, a paddock or a commercial frontage.
Up to 3 ft, stated as 1 m, is depth. And here the listing does something unusual: it qualifies the number in the same breath. The 3 ft figure is given for open muddy environments, and then the bullet says that in environments such as steel pipes, iron pipes and PVC pipes the signal will attenuate at a depth of 1 to 2 feet.
Both halves of that are useful. The reason damp open ground is the best case is that the signal needs a return path through the earth, and wet soil provides a much better one, so more current flows and the field the receiver is hunting is stronger. The reason metal conduit is the worst case is that steel and iron redistribute and absorb the magnetic field the receiver depends on.
The inclusion of PVC in that same sentence is the odd note, since plastic does not shield a magnetic field the way steel does. The practical reading is that any ducted run should be planned around the 1 to 2 ft figure rather than the headline, whatever the duct is made of, and that is a sensible default for most installed cable. Few listings in this category tell you where their own number stops working.
Single and dual core, because crosstalk is real
The third bullet states the instrument is for tracing single core and dual core wires and is not suitable for multi core, bundled or stranded wires, which may cause crosstalk between target and non target cables.
That is the correct term and the correct reason. The receiver finds a conductor by sensing the magnetic field around the current the transmitter is pushing through it. Put other conductors immediately alongside and the signal couples into them, and each one becomes a secondary source radiating the same signal from a slightly different position.
What you see then is not a failure message. It is a confident reading in the wrong place, or a peak that wanders as you walk, or two apparent routes where there is one cable. That is the worst failure mode an instrument can have, because nothing on the display tells you to distrust it, and the listing naming the condition in advance is genuinely protective.
It also tells you something about expectations on a dual core run, which is the common case for irrigation and fence wire. With two conductors, the field from the pair partly cancels, and the usual technique is to clip to one conductor and earth the other end so the current goes out along the wire and back through the ground rather than back along its partner.
The screwdriver trick explains the whole circuit
The second bullet ends with a field tip: if the cable signal is weak, attach the black alligator clip to a metal screwdriver inserted into moist soil to boost signal reception.
Read that as a diagram rather than a tip. It tells you the transmitter needs two connections, one to the conductor and one to earth, and that the signal travels out along the cable and home through the ground. Everything else about the instrument follows from that one fact.
It explains why damp ground gives the deepest results, why a dry summer makes the same cable harder to find than it was in winter, and why pouring a watering can over the earth stake is a legitimate technique rather than a bodge. It explains why the depth figure is quoted in mud. And it explains why a poor earth shows up as weak signal everywhere rather than as an obvious fault: the whole circuit is current limited at the return.
The flashlight and the headphone jack are smaller additions in the same practical spirit. A tracer is used in crawl spaces, ceiling voids and basements where you need a free hand and light. The jack is the more valuable of the two, because peaking a signal by ear is both faster and more sensitive than watching an indicator, and it works in a noisy yard. Our page on cable tracers covers how much difference audio makes to pinpointing accuracy.

The first blank row is the significant one. Signal frequency is the specification that predicts how a tracer behaves: lower frequencies travel further along a conductor and couple less readily into neighbouring ones, higher frequencies couple more easily and so find poorly connected or broken runs, but also bleed into everything nearby. Without the figure, you cannot predict in advance which of your jobs this will suit, and you cannot compare it with another instrument on anything but the range claim.
The missing ingress rating is worth a note too, since this is a tool used on wet ground by definition, and the receiver is the part that gets laid down in it.
For irrigation and fence wire, not for a live circuit
This is a sensible buy for a landscaper, an irrigation technician or a homeowner with a buried run they need to find before digging. The jobs it names are the jobs it fits: sprinkler wiring, invisible fence loops, communication cable and dead buried feeds, in gardens where a trench in the wrong place costs more than the instrument. The audio output, the long tracing range and the honest depth qualification all point the same way.
It is the wrong tool for anyone who needs to identify live circuits, map multi core or bundled cable, or report a depth to a utility standard. Those are three separate exclusions and the listing states all three rather than letting a buyer discover them in a trench. An electrician whose work is mostly inside a consumer unit should be looking at a live circuit tracer instead, and anyone working near buried services should treat any tracer result as an indication rather than a permit to dig.

Frequently Asked Questions
Can I use it to find which breaker feeds a socket?
No. The third bullet states it is designed for locating non energised wires only, which rules out circuit identification on a live board. A tracer of this type injects its own signal onto a dead conductor and listens for it, so the circuit has to be isolated and disconnected first. Finding a breaker on an energised circuit is a different instrument with different insulation and a different safety rating, usually sold as a circuit breaker finder.
How deep will it really go?
The listing gives two numbers, and the second is the honest one for most gardens. Up to 3 ft, around one metre, applies in open damp ground with nothing else in the way. Where the cable runs in or near steel, iron or PVC pipe, the same bullet says the signal attenuates at a depth of 1 to 2 feet. Most real installations are closer to the second case than the first, so plan around 1 to 2 ft and treat 3 ft as the best day you will have.
Why does damp soil help?
Because the injected signal has to return to the transmitter, and in this arrangement the return path is the ground itself. Damp soil conducts far better than dry soil, so more current flows along the target conductor, and the magnetic field the receiver is listening for is proportionally stronger. This is also why the listing suggests clipping to a screwdriver pushed into moist soil when reception is poor, and why the same job can be easy in spring and impossible in a drought.
What goes wrong on a multi core cable?
Crosstalk, which is the term the listing itself uses. The injected current couples into the conductors running alongside the target, and each of those then radiates its own field. The receiver sees several overlapping fields rather than one, so the peak it is trying to follow smears out or jumps between conductors. That is why the instrument is specified for single and dual core only, and why a bundled or stranded run will produce confident readings in the wrong place.
Is the headphone jack worth using?
More than it sounds. Peaking a tracer means finding where a signal is loudest, and hearing is good at small changes in level while watching an indicator rise and fall is not, particularly while you are also watching where you are walking. Headphones also remove the mowers, traffic and conversation that make a speaker useless in a front garden. The listing describes it as an independent jack that blocks ambient noise, which is the right reason to include one.
