Engineered for municipal departments managing mixed underground utility corridors. The XHGX507 detects both power cables and metallic pipes with a single instrument — eliminating the need for separate cable and pipe locators. Multi-frequency operation (815Hz to 83kHz) with three working modes adapts to any field scenario. From urban utility corridors to rural pipeline routes, one person can map it all.
Three Working Modes — One Instrument
🔌 Direct Connection
Highest accuracy for accessible cables. Physically connects the transmitter to the target conductor for maximum signal injection and longest detection range up to 15km.
🔗 Coupling (Clamp)
Non-contact signal injection via clamp accessory. Ideal for live cables or pipes where direct connection is not possible. Safe, fast, and non-disruptive.
📡 Induction
Fully non-contact scanning mode. Walk the area with the receiver to detect buried utilities without any physical connection — perfect for initial site surveys and unknown utility corridors.
Product Details
XHGX507
XHGX507 underground cable pipe locator is mainly used for cable fault location, cable identification, cable path and depth measurement. It can complete tasks that could only be accomplished by a few sets of instruments in the past.
Working principle
The underground cable pipe locator is designed based on the electromagnetic induction method and the application of the communication principle.
1.The electromagnetic signal is generated by the transmitter, and the signal is transmitted to the underground cable under test through different transmission connection methods.
2.After the underground cable induces the electromagnetic signal, an induced current is generated on the cable, and the induced current propagates along the cable to the distance.
3.In the process of current propagation, electromagnetic waves are radiated to the ground through the underground cable. When the receiver detects on the ground, the electromagnetic wave signal will be received on the ground above the cable.
4.The position, direction and fault of the underground cable can be judged by the change of the received signal strength.
Features
●The large-screen LCD displays the signal strength, and the bar, arrows and voice prompts make it easy for the operator to judge the underground position of the cable and the fault point. One person can do it all.
●All-digital design, clear large-screen LCD graphic display and reliable positioning
●Portable and lightweight, easy to carry
●Built-in rechargeable battery
●Built-in ohmmeter to measure cable loop resistance
●Can be used to detect insulation faults up to 2MΩ to ground
●With backlight function to adapt to night operation
●Built-in ohmmeter to measure cable loop resistance
●Display cable depth and current
Main components

▎Frequently Asked Questions
Q: What types of underground utilities can the XHGX507 detect?
The XHGX507 is designed to detect a wide range of underground utilities including power cables (energized and de-energized), telecommunication cables, metal water pipes, gas pipelines, and other metallic conduits. Using the electromagnetic induction method with selectable frequencies, it can distinguish between different utility types based on signal response characteristics.
Q: How accurate is the depth measurement and what factors affect it?
The instrument provides direct-reading digital depth display with accuracy varying by frequency mode. Low Frequency (LF) typically achieves ±(1-5)% accuracy, while Radio Frequency (RF) achieves ±(5-12)%. Factors affecting accuracy include soil moisture content, proximity to other metallic objects, signal quality, and operator technique. The 45-degree and 80% verification methods are recommended for confirmation.
Q: Can the XHGX507 work in areas with high electromagnetic interference?
Yes. The instrument supports multiple operating frequencies and gain adjustment (0-100dB dynamic range) that allow operators to select the optimal frequency and sensitivity for noisy environments. The Peak and Trough antenna modes provide complementary detection methods—Peak for fast tracking in clear areas, Trough for precision positioning in high-interference zones.
Q: Is pre-excavation training required to operate the instrument?
The XHGX507 features an intuitive interface with real-time signal strength display, audio tone proportional to signal strength, and clear directional indicators. Most operators become proficient within one day of field use. For organizations requiring formal certification, on-site training programs are available upon request.
Q: What warranty and after-sales support is provided?
12-month standard warranty against manufacturing defects with lifetime technical support. CE and ISO 9001:2015 certified. The complete kit includes receiver, transmitter, connection cables, ground rod, rechargeable batteries, charger, user manual, and a rugged transport case. Extended warranty plans and on-site commissioning are available upon request.
