Which tool can help you find a network cable in the walls of a building?

Posted on: January 14,2022

Locating the underground wires and cables can be a tedious task. Without proper tools and equipment, you have no choice but to go with the traditional ways of hammering and damaging the walls and ground to trace the deeply buried cable. Sometimes, you may even break or injure the electric wiring. Another way is to find the electrical blueprints of your building and then trace the cable and electrical wiring. Again, this is quite tiresome work as not everyone can understand the electrical and architectural blueprints. Tracing the electrical wiring buried in the walls and underground can be a tricky task. It implicates more than merely looking for the wires themselves.

Luckily, at Noyofa, we have electrical tools that help you locate and trace underground wiring and cables with ease.

 What is an underground wire locater tool?

An underground wiring tool is used to locate and detect the underground wires and cables. The magnetic wire finder tool detects the nails and magnetic fields around the electrical wires. The electrical stud finder tool produces a small electrically charged domain that changes when the finder reaches a denser region in a wall.


We will be mainly focusing on two tools here.Noyafa NF-816L and Noyafa NF-826


Noyafa NF-816L:

Noyafa NF-816Lis an in-house designed tool used to detect pet fence wires, metal wires, metal pipes, and electrical wires. It is used to detect single-strand wire and or double-strand wire. It can detect accurately up to 4 feet deep and 2000 feet in length. When the cable is identified, a tone signal is produced on the tracer.


It comes with a rechargeable lithium battery with a low battery signal. The consumer can use it to locate non-energized wires. An open circuit or short-circuit fault is detected more simply.


This electrical equipment has been passed and ensured to meet the highest safety standards.Noyafa NF-816LPasses RoHS, FCC, and CE compliance testing, and Noyafa are certified to the ISO 9001 standard.


Some essential features list:

● Locates broken wires and solenoids

● Lightning and irrigation cables

● Trace underground wires

● Includes headphones

● Low battery warning

● Trace in-wall wires

● +ve and -ve clips

● LED lighting


Noyafa NF-826:


Noyafa NF-826 is a more advanced tool than NF-816L. It is used to detect network cables, line direction, breakpoint, and short circuits buried in the wall. It can also find fuses, fuse circuits, covered sockets, and junction boxes. The transmitter comes in two modes; automatic and manual mode. The depth detection range is 0~2.5m, and the length detection range is 2KM.  


Like all products at NOYOFA, we take pride in making sure that our products pass the highest safety standards and compliance.Noyafa NF-826 Passes RoHS, FCC, and CE compliance testing, and Noyafa are certified to the ISO 9001 standard.


Some essential features list:

● Network Cable positioning

● Cable breakpoint search

● Cable short-circuit point search

● HD by light

● AC/DC voltage

● USB direct charge

● NCV test pencil

● Adjustable sensitivity

● Electric torch

● Illumnious LCD screen

● The device comes with a bag and necessary items


Best Practices while detecting underground wires and cables:


Our equipment comes with basic handling and best practice instruction to use the products efficiently. Here, we are sharing some tips for our readers to get started with best practices.


No one way works for all, as it depends on your requirement. You may start by first checking the main circuit board, unplug the connection from the socket, and switching off the main circuit board for best safety. It is suggested to make an analysis diagram of your project; where your wires are and to what outlets they connect to. Once you locate the path of the wire on paper, you can easily trace them with our tools.


Safety concerns:

There is always a safety concern when working with electricity. You need to be compliant with the following safety tips:

1. Cut the power at the circuit breaker

2. Wear electricity shock safe gloves

3. Use caution while testing wires

4. Use eye protection if necessary

5. Try to use non-conductive tools

6. Unplug appliances before flipping circuit breakers
