Cable locator NOYAFA NF-820 — locates cables and measures depth up to 2 m, suitable for high and low voltage lines

NOYAFA NF-820 is a cable locator designed to find and trace buried power and communication cables and to estimate their burial depth up to 2 meters. The instrument supports detection on both high-voltage and low-voltage lines and provides directional signal tracing to assist field technicians in identifying cable routes. The product is intended for utility, construction and telecommunications applications where avoiding accidental strikes during excavation, maintenance or installation is required.

Advantages

The NOYAFA NF-820 combines tracing capability with a depth estimation function that reaches up to 2 m, enabling on-site personnel to assess approximate cable position and depth before digging. It supports both high-voltage and low-voltage detection, which makes the device adaptable to a variety of buried conductor types. The design focuses on practical field use by simplifying signal recognition and helping to reduce the risk of damaging underground infrastructure.

Suitable for

• Locating buried power cables in urban and rural sites
• Tracing communication and data lines prior to excavation
• Verifying cable routes during maintenance and installation
• Utility and telecom survey work where depth indication is required

Key specifications

• Detection capability: supports both high-voltage and low-voltage lines
• Maximum depth indication: up to 2 meters
• Primary functions: cable tracing and depth estimation
• Intended environments: construction sites, utility corridors, telecom sites

How to use

Place the NF-820 on the surface above the area where buried cables are expected and move the unit along a systematic survey path to detect the strongest signal trace. Use the device's signal indicators to follow the cable route and to identify the approximate position. For depth estimation, position the locator where the signal is strongest and read the depth indication; the device provides an approximate burial depth up to 2 m. When working near known high-voltage lines, follow safety procedures specific to the site and observe safe distances while performing tracing. Consult the product manual for details on power-up, calibration (if applicable) and signal interpretation to ensure accurate readings.

Usage recommendations

Use the NOYAFA NF-820 as part of a comprehensive site safety routine: confirm live line status, mark detected routes clearly before excavation, and combine acoustic or visual indicators with manual verification. For more reliable results, perform multiple passes at different angles and avoid locations with heavy electromagnetic noise; when in doubt, contact utility owners for confirmed cable plans.
