An underground wire locator instrument helps in accurately locating the path of the underground wires. It also measures the accurate depth of the invisible underground wires. An underground wire locator comprises two parts - a transmitter and a receiver. An AC generator that supplies the signal current to the underground cable to be traced is a transmitter. The transmitter may typically set the signal at a particular frequency.
The transmitter places an electrical signal on the traced cable, while that signal is picked up by the receiver, allowing the locator operator to track the direction of the signal and follow the located cable.

Understanding the basic principles of an underground wire locator is important. It will prepare you to effectively use Leica’s underground wire locators. It will enhance your ability to determine target location, target depth, and tracing distance. There are two methods of underground wire and pipe location. Both of which require the underground wire to conduct electricity. It simply means they must be metallic.
Active locating is regarded as the first method. Since a transmitter is used to impose an electric current on the piper cable to circulate. For detecting the field produced by the current, a receiver is used.
The second technique is referred to as passive locating. Because a field formed by the current that is already circulating on the cable is identified by the receiver. It does not need any transmitter.
Active locating allows you to build an electrical circuit that can flow through the current. This can be done with three different forms of connections.
The three connecting active modes are direct. Also known as conductive, inductive, and inductive clamps. The direct mode generates the greatest amount of current and increases the success of localization. Less current is generated by the inductive clamp mode. But when the lack of access to the underground pipe or wire prevents you from using the direct mode, it's a reasonable option.
First, take the clip attached to the red cable. Apply it directly to the wire you are trying to locate. Make sure there is a good metal-to-metal contact.
The next step is to position a ground stake as close to 90 degrees as possible to the expected line location path. Press the stake deep into the ground to increase surface contact with the soil.
Once the ground stake is in position, apply the clip attached to the black cable to the ground stake. This is to complete the circuit. It’s important to complete the circuit by properly implementing aground. In general the better the ground the better the signal.
Now a current will flow through underground wire. As the signal travels it gradually leaks into the ground and diminishes the further it gets from the transmitter. One of the keys to getting a good signal is applying the proper frequency.
If conditions are good, good conductor connections, and soil conditions. The current will travel farther at the lowest frequency with less leakage to adjacent structures. An increase in frequency will cause the signal to leak sooner and cover less distance. As a rule, always start with the lowest frequency possible.
Gradually increase it as needed. Remember at higher frequencies, the current will leak to the ground quicker. Which might impact your ability to locate underground utilities.
Underground wire locators use electromagnetic detection to find buried utilities. These devices generate a magnetic field that interacts with the conductors in underground wires, pipes, or cables. The strength and direction of this field help pinpoint the location and depth of buried objects.
The process involves transmitting a radio signal through the ground and detecting its reflection. Different frequencies are used for various types of utilities and soil conditions. Higher frequencies work well for shallow burials, while lower frequencies penetrate deeper into the ground.
Modern wire locators from reputable brands incorporate advanced sound technology to aid in detection. These devices emit distinct audio tones that change in pitch and volume as the operator moves closer to the buried utility, enhancing accuracy and efficiency in the field.
Active locating methods involve using a transmitter to send a signal through the wire or pipe, which is then detected by a receiver. This technique provides precise location data and is often used with tools like metal detectors or specialized underground wire locators. Active methods are particularly effective for locating non-energized lines or pet fence systems.
Passive locating relies on detecting existing electromagnetic fields generated by live power lines or radio frequency signals. This method doesn't require a transmitter and can be useful for initial sweeps of an area. However, it may not be as accurate as active methods and might miss non-energized lines. Some advanced tools combine passive detection with multimeter functionality for enhanced utility.
The choice between active and passive methods depends on the specific job requirements and site conditions. Professional locators often use a combination of both techniques, employing tools with backlights for better visibility in low-light conditions. This comprehensive approach ensures the most accurate and efficient location of underground utilities.
