Benefits of Wire Tracers

  • Efficient. Wire tracers are specially designed to locate wires in hard-to-reach areas. These days, wires run underground or through the walls, which makes them harder to trace. With a proper tracker, you can locate wires with ease, whether you're in a home or commercial environment. 
  • Time-saving. A wire tracer also saves you a lot of time you would otherwise spend trying to figure out there the wires go. It can locate wires both underground and in walls within a few minutes, allowing you to perform any repair rather quickly.
  • Easy on the budget. Wire tracers are smart investments because they last for a long time. They allow you to trace wires, network cables, and open circuits for years, saving you a lot of money on electricians and other related expenses. Wire tracers are not expensive, so you won't have to spend a fortune to get one in the first place.

Active Tracing 

There are two methods of checking for wires and cables with wire tracers. The first one regards active locating, which is convenient for those who need to locate specific lines, pipes, and more. A wire tracer charges a specific line with electricity and uses a receiver to pick up the generated signal. It does that by using a direct connection or by emitting a signal. Some devices require direct attachment to the line, while others only have to be well positioned on the ground above the particular line. 

Passive Tracing

The second method is called passive wire locating. It is used when a targeted line is already charged with electricity. The tracer picks up the signal without the help of the receiver. This method, however, won’t help you find a specific wire in wire pairs or groups. It will detect power in a specific area and help you secure the place prior to drilling or other activities.

Key Features


Consider what type of wire tracer you need in the first place. Some of them are specifically designed for certain conditions and environments and might not work for all purposes. Along with the two main types of wire tracers (active or passive tracing), there are also several other models. There's an underground wire tracer that can help you with finding wires buried deep under the ground or circuit breakers for locating power issues. Determine which type works best for your specific issues and pick a model accordingly. 


Along with choosing between an active or passive wire tracing, you can also opt for a particular attachment type. Some wire trackers need to be attached to the network directly, and only then they can send the signal and detect specific lines, power issues, and more. Others, however, use clamps or alligator clips to send the signal when there's no direct access to the line. 

Adjustable Features

Whether you're a professional or a DIYer, you'll need an adjustable receiver. It will allow you to pick up the signal of a different range, and consequently, detect and locate wires faster and more accurately. The best wire tracers have adjustable sensitivity modes, and users can set them up according to the situation and environment. 

Other Considerations

  • Range. Not all line finders have the same range. Although most of them detect the signal at around three feet deep and 100 feet length, that can vary a lot depending on the model. These standard wire tracers work just fine for home purposes, but you might need the one with a higher range for professional purposes. 
  • Construction. It's also important to look for a device that comes with a rugged case for more durability. Home inspectors can go with a less durable wire tracer, but professionals might want to get a sturdier model. They are likely to use the device frequently and store it with other tools, which can cause damage and shorten the lifespan of a wire tracer. 
  • Additional Accessories. Consider what extra features and accessories you might need in the future. You might need the extra range at some point, as well as signal clamps and other accessories. If you have the means, you could invest in an all-purpose tracer that would work on all kinds of cabling and last for many years. 

Best Wire Tracers Reviews & Recommendations 2021

If you're looking for a reliable device to help you detect, prevent, and resolve electrical issues, the Kolsol wire tracker is an excellent choice. It's an efficient device that traces all kinds of hidden wires, from pet fences to metal pipes. 

The Kolsol wire tracer comes with an impressive range of up to three feet in depth and 1,000 feet in length. That should be enough to let you tackle all electrical issues, from commercial to DIY ones. The tracer also accurately traces circuits and wires buried underground and behind walls. In addition, it's compact, lightweight, and easy to transport. 

The main drawback of this wire tracer is the fragile outer shell. It's made of plastic, feels a bit flimsy, and might break easily. The device, therefore, is not a perfect option for daily use where it can be highly exposed to damage. Also, the tracer works only on single strand wires, which means it can't locate and differentiate specific wires in a group.

This wire and cable tracer is ideal for those who are looking for a versatile yet budget-friendly device to help them track lines behind walls or those buried underground. It's also handy for checking the status of network and telephone lines. Thanks to the user-friendly design, it's suitable for everyone—even first-time users can get the hang of it. 

The wire and cable tester is easy to maneuver, and it comes with a comprehensive manual that contains all the necessary information. What makes it even more appealing is the signal range of up to 3,000 meters. The tracer is quite powerful and can locate wires in different environments. It even has a loud signal sound and multiple-color indicator light for easier coordination. Additionally, a pair of earplugs and a storage bag are included in the package. 

It's important to note that this device is not a perfect option for commercial use, although it does give accurate results. Unfortunately, the tracer might break or malfunction if it's used daily or not handled carefully. Also, the button on the probe is flimsy and might accidentally turn on the tracer. The included earplugs are not of the best quality either.

Extech offers a high-quality tracing kit for detecting electrical issues. Along with detecting wires, this kit can also help you locate circuits, installation defects, and other malfunctions around the house. It's also quite handy for professionals because it's very powerful and highly efficient. 

The wire and circuit tester features a unique snap-on design. A transmitter and a receiver snap together for easier transport and storage. The tracer is ergonomically designed and pretty straightforward. It comes with an LED light and an audible alarm, so the results are easy to read. There's also a sensitivity adjustment button that allows you to set up the signal and detect wires in every situation. 

The button, however, doesn't have increment markings, so setting it up might be quite a challenge. It also feels a little loose. Another thing that requires careful handling is the outer shell in general. It’s rather fragile and might break if dropped or damaged in any other way.

The Klein Tools Cable Tracer is a high-grade tool for finding and testing wires. It’s built with a strong plastic housing and includes durable ABN (angled bed of nails) clips that grip wires securely without pinching or damaging them. It’s simple to use and helps save time in the long run.

By far, one of its best features is its audible alerts. The device comes with five distinct tone cadences that alert you to different types of wires. It can also detect wires that are up to 1,000 feet away. It’s an accurate device that is compact, lightweight, and easy to carry around, either in your pocket or in a box.

While the tool may not be overly expensive, it is mid-range when it comes to price. There may be issues with the speaker not being loud enough to hear without headphones, but it does include a headphone jack for extra versatility. Also, the buttons can be turned on quite easily if it is left in a bag or pocket.

The Fluke Networks Tone Generator is designed by a top-of-the-line manufacturer. It’s a premium wire tracer that is ultra-sleek and compact, but mighty in power. It’s meant to test wires on non-active networks and is set up with five tones for multiple ways to identify wires and cables around the house or workshop.

It also includes a completely replaceable tip. It features a great grip and ergonomic handle so it is easier to hold onto. Also, perhaps its best aspect is its loud and clear speaker. But if that doesn’t work, you could always use its included 3.5mm headphone jack. It saves you time by allowing you to track down wires in minutes as well.

It is a pricey wire tracer device, but it isn’t absurdly expensive. There have been complaints with the RJ11 port not being adaptable with the RJ45 connector. Also, the batteries may not be included with the tool. The buttons may also get turned on if you leave it inside of a tool bag and move it around. It’s small and can get squished more easily inside the bag too.

The PTE Wire Tracer and Circuit Tester features a simple yet elegant-looking design. It’s another great budget-friendly choice for a wire tracer kit that is accurate and simple to set up and use. It’s capable of detecting wires through ceilings, floors, and walls with its strong tone signal. It functions quickly and works at a depth of up to 10 feet.

Continuing with the simplicity of the tool, it has a variable sensitivity dial that lets you cycle through different wires until it identifies the correct one you’ve found. It’s precise and handy enough to fit in your pocket, a drawer, or a tool chest, too. 

Sure, the tool won’t win any awards for how it looks, but it’s functional. It’s a cheap wire tracer that is designed for the everyday homeowner and not the mechanic or electrician. It’s better for small projects and may not be the best for larger buildings. The audio through the speaker may not be the loudest either.

The Sperry Instruments Wire Tracker Wire Tracer is a tool designed to help anyone with their audio visual troubles. Keeping track of cables can be annoying, and this little tool helps track down RJ45, RJ11, and coaxial cables behind walls and floors. It’s not difficult to adjust its sensitivity levels and is all around easy to use.

When it comes to price, the wire tracer is on the lower end of the spectrum. It even fits snugly and securely inside of a slot designed in the device itself. The audible tones are loud, the plastic case is tough, and it is able to detect cables a few feet deep. Also, even though it isn’t a premium priced tracer, it can differentiate between several types quickly and conveniently.

The batteries are not included with the device, so you will have to spend a few extra bucks on batteries. It may not be able to find cables that are super far away—not 1,000 feet for sure—but is great for those just behind drywall or insulation.


  • The price of wire trackers could vary a lot depending on its purpose. You can find an excellent cheap tracker for home purposes and detecting wires occasionally. If you need a professional-grade tool, however, you'll need the best tracker that money can buy. 
  • Check the voltage power of a wire tracer before you use it. Not all devices are made to withstand the same amount of power. If the voltage of the source is higher than what the tracer can endure, the results won't be accurate. This can also cause a short circuit.
  • Perform the necessary tests to see whether a wire tracer works well. It's important to know that the probe and the transmitter are at their peak power before you start tracing. Once you set the probe's sensitivity to a maximum level, move it towards the transmitter. It will allow you to check the connectivity and alert you about possible issues. 


Q: What is a wire tracer?

It's a device that tracks wires and cables located deep inside walls, underground, or in water. It also identifies specific wires in a set or groups of other wires in the same connection. A wire tracer is perfect for detecting wiring issues and malfunctions in houses. It is also helpful in professional electrical tasks.

Q: How do wire tracers work? 

Every wire tracer has a transmitter, a receiver, and a probe. The probe itself has three sensors. They are meant to locate a wire and determine in which direction the current goes. The probe points to a particular area, and the sensor catches the signal. The transmitter produces a unique signal that is detected by the receiver. Lastly, a receiver provides a numeric value that will depend on the signal strength. 

Q: What are the most common types of wire tracers? 

The main difference between wire tracers is each one’s ability to locate energized or non-energized wires. Some of them can locate both wire types, but most models are specialized for only one of them. There's also a type of circuit tracer that detects the circuit and its voltage.  

Final Thoughts

The Kolsol Wire Locator is our top pick when it comes to wire tracers. It’s reliable, quick, and easy to use. If stored properly, the device can be used for DIY purposes and some professional applications.
