Underground Utility Locator Tools: Which One Is Right for You?

Underground Utility Locator Tools: Which One Is Right for You?

When you're picking the right underground utility locator, it depends on what kind of job you're doing. If you want something super advanced and smart, the Leica DD series is a solid pick—it's user-friendly and gives you in-depth info. Ridgid SR-20 is another great one if you need something fast and flexible. It locks onto signals quickly and has a transparent screen that helps you see what's happening underground. For bigger or more detailed jobs, the Radiodetection RD1500 uses ground-penetrating radar and can find stuff more accurately. So whether you're a contractor, utility worker, or inspector, think about how deep you need to scan and how much detail you want—then choose the tool that fits your workflow best.


Choosing Locator Features Wisely

When shopping for a utility locator, focus on the features that make your job easier and more accurate. Look for multi-frequency support to scan different types of lines with one tool. A transparent display is also essential—it helps you see signal strength, depth, and direction without guessing. GPS and data logging are significant if you want to keep track of where you've scanned. Also, ensure it's lightweight and easy to carry, especially if you're on site all day. Some models even offer Bluetooth or mobile app connection, which can help you map your findings in real time. These key features can save you time and help you avoid costly mistakes.



Choosing Locator Features Wisely

There are many types of utility locators on the market today, but all of them are meant to find underground utility sources at a job site. While advancements in technology have made them more reliable, the basic principles of an underground utility locator have stayed the same.Pipe locators and other types of location equipment have been the standard way for finding utility lines and other objects underground, which they do by sending an electromagnetic frequency through the conductive material of an underground facility.

A similar principle is used to find water pipes. You apply the signal to the pipe at a riser, hydrant, or valve. And if you want to find an underground cabling system (such as an electrical or telephone line), you connect it to the grounding structure of the utility system. Power lines can be located by connecting the unit to a meter box, transformer, or ground wire. Telephone and Cable TV lines can be found by transmitting a signal to the ground cables inside a pedestal, manhole, or interface box. Once the signal has been sent to the target utility, you can detect the transmission on the surface by using a device that’s designed to receive the signal. Utility locators will come with this type of device, which is set to the frequency being transmitted. But many receivers can be reprogrammed to detect additional frequencies if the situation requires it.

You can also use utility locators to look for natural radio transmissions — ones that match the frequency you’re trying to locate. This is called “passive locating,” which is a less reliable method of using an underground utility locator. It can also be misleading, which is why an active location method is always preferred. Many types of utilities can transmit the same frequencies, which can make it harder to use utility locators in this manner.

Frequently Asked Questions

Can a utility locator find plastic pipes?

Regular locators find metal pipes, but plastic ones need a tracer wire or special equipment like ground penetrating radar (GPR).

What happens if I hit a utility line while digging?

Hitting a line can be serious — you could lose power, flood the area, cause a gas leak, or even get hurt. That’s why using a utility locator first is so important. And if you do hit something, stop work immediately and call the utility company or local authorities.

How deep can a utility locator detect?

It really depends on the model and the conditions underground. Some basic locators can find utilities a few feet down, while advanced ones (or using GPR) can detect stuff 10 feet deep or even deeper. Always check the locator’s specs to know its range.

What happens if I hit a utility line while digging?

Hitting a line can be serious — you could lose power, flood the area, cause a gas leak, or even get hurt. That’s why using a utility locator first is so important. And if you do hit something, stop work immediately and call the utility company or local authorities.

How do you use a utility locator?

The utility locator needs to be attached directly to the line or if you cannot make a direct connection to the line, a frequency is selected and inducted into the ground and reradiated by the utility.
