Best Underground Cable Locators Review

Underground cable/wire locators are devices that assist in discovering and identifying buried cables and wires. They work by emitting a signal that travels through the ground and then is picked up by the receiver. It allows the user to see the location of the cable on a display or map.

There are many benefits to using wire finders. First, they can help you save time and money. By locating wires before you start digging, you can avoid unnecessary damage and delays. They also help you stay safe by preventing accidental contact with live cables. Finally, underground cable locators simplify your job by providing correct info about the placement of cables, allowing you to work more effectively and avoid costly mistakes.

However, finding the best underground wire locators may be a challenging, nerve-wracking task. When there are so many options on the market, it’s difficult to decide which product is right for you.

How does an underground cable locator work?

Today, many cables are buried under the ground, making an underground cable locator an exceptionally useful invention. The demand for such a locator is only increasing. So, let’s discuss what it consists of and how it works.

The transmitter, which is often called a “snake,” and the receiver, sometimes known as a “worm,” are the two components of an underground wire tracer.

The wire’s location will be illuminated by the transmitter, which sends an AC current to it. As the current continues to flow, the electromagnetic field is generated. The receiver detects that electromagnetic field and allows it to follow its course; you’ll also know its depth. Moreover, the wire locator may help you find the breaks without extensive manual digging.

There are two types of location: active and passive, so let’s take a closer look at them.

Active location

This approach employs both a transmitter and a receiver to locate underground wires. It’s quick and straightforward to use Active Location. It’s also extremely precise, though it can be hampered by metal objects or electrical interference.

Passive location

This method does not require the use of a transmitter. Instead, the cable produces its own electromagnetic field, which the receiver picks up.
Professionals often use the passive location for the detection of live cables. However, it’s worth noting that passive location is not always as exact as active location.

Underground wire locator buying guide

When choosing an underground wire locator, there are a few things to consider. Here they are:

Work depth

When looking for an underground wire locator, it’s essential to consider the work depth. It is the greatest depth at which the finder can discover objects. Most tools have a working depth of around 12 feet, but some can go as deep as 24 feet. If you need to find something buried deeper than that, you’ll need a particularly-designed locator.

Frequency range

The frequency of the underground wire locator is capable of finding buried wires very effectively. 33kHz is a high-frequency option, whereas 1kHz is a low-frequency choice.

The high-frequency adjustments are appropriate for finding long-distance transmission items. The major disadvantage of the low-frequency approach is that it is relatively weak and may easily pass through a lousy conductor.

The high frequency breaks through the rusted wires fairly effectively. On the other hand, it travels more slowly and bleeds out more quickly. Therefore, make sure the underground wire locator you purchase has a wider frequency range to complete all of your tasks successfully.

Additional features

When shopping around for an underground cable locator, it is important to think about the additional features that the unit offers. Some features to look for include LCD clarity, internal GPS/GNSS receiver, overload protection, and strike alert feature.

  • In all weather circumstances, the LCD clarity is critical for clearly seeing the readings on the screen. Several brands also have graphical panels with bar graphs and a numerical SSI measurement to better convey signal strength. Some LCDs also have a compass display that shows the overall direction of subsurface utilities.
  • The integrated GPS/GNSS receiver is a convenient feature that automatically adds positional data to log entries. This is excellent for training or tracing cables in a specific spot.
  • Due to the overload protection mechanism, the cable finder can generate an accurate reading even when there are many outside disturbances.
  • When the unit detects a buried potentially harmful object, the strike alert feature notifies you. In addition, if the device has a depth estimate functionality, this information can also be recorded.


Can metal detectors find underground wires?

No, metal detectors cannot find underground wires. They are only able to detect metal objects that are above ground. If you’re looking for underground wires, you’ll need to use a special device called a locator.

How do you know if a cable is buried live?

If you’re not sure whether or not a particular cable is buried alive, you can always contact your local utility company. They will be able to tell you for sure.

How do you find buried fiber optic cable?

Fiber optic cable is made of glass, so it can’t be detected by a metal detector. The only way to find it is to use a special device called a fiber optic locator.

How deep are electrical cables buried?

The depth at which electrical cables are buried varies depending on the location. In general, they are buried between 18 and 24 inches below the surface.

Can you bury wire without conduit?

Yes, you can bury wire without conduit as long as it is properly protected from the elements. You may need to use a special type of cable called direct burial cable.
