Top 5 Best Electric Wire Detectors of 2023

Are you planning on carrying out an excavation? If you answered yes, you could be aware of how dangerous an activity is. Without an appropriate location, excavation is extremely dangerous. It's highly probable that you will hit the buried wire, resulting in catastrophic consequences. A wire locator is essential for locating concealed wiring.


The Common Ground Alliance estimates that there are approximately 20 million miles of underground utilities in the United States alone. This undoubtedly raises the possibility that the excavation site may contain underground hidden electric lines.


Here comes the role of an underground wire detector that will help you save time and money by detecting the course of hidden/buried wires and measuring the depth in a simple, accurate, quick, and affordable way.


Not only does this wire locator reveal potential breakage, but it also helps you avoid digging in the wrong place.


Finding the best underground wire locator on the web can take time and effort. Here are the top five best underground wire locators, as determined by our research. Please continue reading to get our buyer's guide and other helpful information for your digging needs.


What is an underground wire locator?

The transmitter and receiver are the two primary parts of an underground wire locator. An alternating current (AC) will be sent from the transmitter to the wire. The electromagnetic field is produced when the current flows. The receiver can then trace the source of the electromagnetic field and record its location. You will have a full report of the situation on the ground. On top of that, these wire locators would allow you to find the breaks without spending days digging the ground.


There are two different approaches to tracing the position of barred buried cable and pipe.


Active Locating:

Active locating is the first common method to find out where the target is. This method produces the electromagnetic field when the locator tool sends out a specific frequency without using the transmitter.


Passive Locating:

The passive locating method lacks a transmission frequency feed since it receives the current existing flowing through an underground line.

Klein Tools VDV500-705 tone/probe test and trace kit:

The Tone & Probe Test and Trace Kit allow for straightforward toning and tracing of wire that is not already powered. When combined with the probe that comes with the tone generator, it is easy to trace wires. Unterminated cables can be secured with the included alligator clips, and an RJ45 to RJ45 cable can be used to test or tone data cables. The responsive probe is a tone tracer that features a long-lasting, non-metallic conductive tip, a speaker that produces an audible output, and headphone connectors for usage in noisy surroundings. The pin-to-pin wire map test is carried out by the toner and the probe working together.



● Adjustable volume control

● RJ45 to RJ45 test cable

● Clearly labeled LEDs indicate the results


● No headphones included

● Weak wand speaker

● It doesn't work well on tracing AC


The Extech CB10 is a circuit breaker finder that is a dependable, portable, easy-to-use, lightweight underground wire locator. It can quickly identify the wires and assist in locating the circuits, installation faults, and other malfunctions around your home and other sites without causing any further complications.



● Ability to find different electrical issues efficiently

● Locate 110V – 125V AC circuit breakers and fuses

● Red and green LEDs indicating the output

● Pluggable GFCI transmitter


● No LED flashlight

● It needs practicing for efficient use

● High sensitivity may give a false reading

Armada PRO871C:

Including the last name on the list, Armada's PRO871C is a good choice that gets the job done and costs less. It is a solid and small tool that makes it easy for users to get clear signals. The built-in transmitter in the underground power cable detector may be easily analyzed to pinpoint the location of cables. In addition, it has a speaker and a volume knob for customizing the audio output. Signals indicating the location of the subsurface wires can be obtained rapidly and clearly.


● Dual frequency transmitter (2Khz and 33Khz)

● Wand and transmitter low-battery lights

● An exceedingly lightweight receiver wand

● Optional inductive clamping


● Subpar build quality

● Can not work with wires which are in metal conduit

● Often gives a false reading

Final verdict:

To put it simply, choosing the top-rated finest underground wire locator is difficult. Determine the circumstances before choosing an underground wire locator. Using a gigantic locator to trace hidden wires is a wrong move. However, the complete feature is essential for a professional task.
