Product Details
- Site Description (Product Overview): The NOYAFA NF-820 Underground Cable Detector & Wire Tracker is a professional anti-jamming tool designed for electricians, cabling installers, home renovation workers, and telecom engineers. It accurately locates hidden cables buried underground, inside walls, above ceilings, or under floor slabs – even in high‑voltage environments (up to 400V AC). With a maximum sensing depth of 2 meters (about 6.6 feet), this wire tracker helps you avoid drilling into live wires, reduce excavation damage, and speed up troubleshooting. Why choose the NF-820? Unlike ordinary detectors, the NF-820 features strong anti‑interference capability, which means nearby live power cables or other electronic devices will not disrupt the signal. You can trace both energized and de‑energized cables safely. The transmitter generates a multi‑frequency pulse signal (output level 21Vp‑p) and connects to the target cable via a red alligator clip (for AC 220V live wires, with proper insulation) or an RJ11 port for telephone lines. The receiver uses an adjustable sensitivity dial (levels 1‑8) and emits a clear “do do do†tone plus flashing signal indicators – the closer you get to the target cable, the louder and faster the sound becomes. Key specifications (for your reference): Transmitter power: 3.7V lithium battery (1800mAh, rechargeable via Micro USB) Receiver power: 3.7V lithium battery (1100mAh, rechargeable) Working current: ≤150mA (transmitter) / ≤80mA (receiver) Signal transmission distance: up to 10km (under ideal conditions) Signal sensitivity depth: 0‑2 meters (adjustable) Transmitter dimensions: 152×55×34 mm / weight 0.143kg Receiver dimensions: 252×45×28 mm / weight 0.200kg Low battery indication: LED flashes when voltage drops below 3.5V (transmitter) What’s in the box? The standard package includes one NF-820 transmitter, one NF-820 receiver, alligator clips, charging cables (Micro USB), and a user manual. Both units are built with durable ABS material and designed for field use. The receiver also features a 3.5mm earphone jack (optional) for noisy environments. Important notes for safe operation: Do NOT use the device to detect live power lines above 400V. When testing live AC 220V cables, ensure the alligator clip’s insulation is intact to avoid electric shock. Remove batteries if the device will not be used for a long time to prevent leakage. Keep the device away from direct sunlight, dust, humidity, and high temperature (>40°C). Whether you need to trace telephone wires, coaxial cables, network lines, or multi‑core power cables, the NOYAFA NF-820 Underground Cable Detector & Wire Tracker delivers reliable performance with easy one‑hand operation.

“The prices—including shipping costs and customs duties—are clear from the very beginning, with no hidden fees. I highly recommend using their services. My experience with the "Ubuy" website was excellent. I purchased a PRS USA Swamp Ash Special guitar, and it arrived in just 11 days. The shipping service was fantastic, and the product arrived in perfect condition. What I particularly appreciated about the site is that the prices—including shipping costs and customs duties—are clear from the very beginning, with no hidden fees. I highly recommend using their services.”
