That is why we must mention below the most important aspects to consider. In turn, this will make it much easier to make the most appropriate decision according to your needs.

Detection System

In particular, this aspect refers to the ability of a cable locator to work in each situation. Here the most convenient options will be those that are perfectly compatible with working with passive or active cables.

In this sense, it is simply a matter of cables that are not energized and cables that are energized.

Therefore, if a locator has this function, the level of versatility for the different tasks is more than wide. In contrast, some pagers can only work with cables that are not powered, i.e. dead cables.

So, in this case, it is not recommended to use such a locator on powered cables.

Frequency Levels

In particular, we should mention here that the options from 33 kHz upwards are a high frequency. In the same sense, a frequency below one kHz is considered a low frequency.

So, the high frequency can be detected at a short distance and the low frequency at a long distance.

Depth Range

If you do not know exactly which cables you need to detect, then a versatile locator would be the best option. In the same way, to obtain measurements with a high level of accuracy concerning depth, the frequency of the probe is required.

That is why the deeper the depth, the more convenient the locator you choose.

Display Type

As with any other instrument, the display of a pager is another important aspect. Of course, not all options can offer the same display quality.

In general, the best options can provide an LCD or LED display. In concrete terms, this quality will allow you to obtain easier and more comfortable visualizations of the measurements.

Beyond that, it is not a feature that is too important to be able to work with. However, the truth is that a good display on a cable locator allows you to optimize and save some working time.


Another component that can facilitate each of the next tasks is this accessory. You may notice that this is an accessory that is not always included in all pagers.

It is also a part that can make your job easier when you need to mark the path of a cable buried in the ground.

Beyond that, it is advisable to purchase this accessory along with the rest if you frequently use your cable locator.

When you have considered each of these options, you will be able to purchase the best tool. Now you can do more efficient and accurate work.

Best Underground Wire Locator- FAQ’s

Q: How do I find a wire underground?

A: To begin, you must connect one end of a wire to the transmitter unit of your pager. Here the transmitter can send a signal through the wire to be received at the receiver.

After that, you will have the ability to trace the path of the same wire in the ground.

If you have a high-quality tool, you will also be able to know the exact depth of a given cable. This may be necessary if you need to dig into the ground.

Q: How do you locate underground fiber optic cable?

A: Here, it is advisable to first insert a cable rod into a conduit. There are other ways, but by doing this you will be able to detect fiber optic cable more efficiently. You can then connect the cable rod to your pager to track the signal efficiently.

You will notice that you can get locations with a high level of accuracy when this procedure is done correctly.

Q: What kind of wire is used underground?

A: Under the floor, you can find a lot of cables used for different purposes. However, not all of them are found in the same quantity along with the different houses or public streets.

For one thing, the underground utility entrance and the underground feeder are the most common underground cables you can find.

In this case, the first option is used very often and its design is black. They are also often used to connect a power transformer to different houses in a city.

This is why they are the most commonly used cables in a city with many inhabitants.

Q: How do you use a wire locator?

A: Here it is necessary to mention that most of the options we have considered in this review are easy to use. So, to begin with, you should locate the bottom as close to the ground as possible.

After making the appropriate settings and adjustments you can start looking for weak or strong signals.

To do this, you will have a set of visual and audible indicators. So, by the time you receive one of these indicators, you will have detected a set of cables or pipes buried in the ground.

In turn, you should consider whether your locator is suitable for power and non-power cables.

Q: How deep are electric lines?

A: When you must work in the ground at a certain depth, you must consider the electric lines down there. So, it may be that the main power lines are located about 24 inches in the ground.

Beyond that, they are not the only wires or pipes you will find when you dig into the ground.

On the other hand, service lines should be located about 18 inches deep in the ground. Of course, each of these distances can vary depending on the design of a home or simply the design of a city.

Water or natural gas lines may also be located at a similar depth as power lines. These are certainly several aspects to consider in any digging task.

Q: How far underground are water lines?

A: Water lines are usually located approximately 36 inches below the ground. This distance is measured from a bar trench or the drainage itself.

So, it can be somewhat difficult to use a locator to detect these particular water lines.

On the other hand, it is also important to consider that a drain is located below the center of the roadway at a distance of approximately 2 feet. Beyond that, this distance specifically may vary depending on different cities.

Thus, a mid- or low-end locator may not work in these cases.

Final Words

While it is not easy to make the right decision, this guide will help you save money. This means avoiding purchasing the wrong underground cable locator.

So, when you have the right tool, you can work more efficiently.

Even this will save you a lot of hassle by avoiding damage to the pipes or cables in your home. And this is more important than you might think since a broken cable in the ground is difficult to repair.

To help you select the best underground wire locator, we have considered different types of underground cable locators. Therefore, it will be much easier to meet each of your needs when working on your home.

In a few steps, you will be able to perform all kinds of tasks easily.
