Best Wire Tracer Buying Guide & FAQ

Below we will look at wire tracers in order for you to be able to choose the best product for your needs. We will talk about the benefits of using a wire tracker and answer your most commonly asked questions below.

Things to Consider When Buying a Wire Tracer

If you’ve done your research you will know that there are many different types of wire tracers on the market. The different in price varies hugely – with some starting around $30-$40 leading right up to $1000 or more. There are a few things you will need to consider when buying a wire tracker. Firstly, is this for occasional use in the home or are you a professional? If you are decorating a house and need to detect if there’s wiring behind the wall before drilling then you can probably opt for one of the cheaper models. Whereas if you’re a professional then it goes without saying that you will need the best quality model that money can buy. Is the receiver fully adjustable? This is a feature that is good to include on your tracer as it allows you to pick up the right signal. Does the wire tracer have multiple features? If you’re making an investment then you might want to look for a tracer that can check for wiring, short and open circuits and more. Range: it’s also important to choose a cable tracer that has a good range. Most tracers can make detections around 3ft deep and 100ft length.

Benefits of Using a Wire Tracker

There are many benefits to using a wire tracker. With the rise in popularity of underground cables and hidden utility lines there is guaranteed to be a complex of cables right under your feet of power lines, gas, sewer, electricity and telecommunications. Not just in the floor either, these wires run through our walls too; in both domestic and commercial environments. Wire tracers and locators have been designed to find energized and de-energized wires, pipes and cables in the wall and underground.

How to Use a Circuit Tracer

There are two methods of checking for wire lines and pipes using a wire tracer; active locating and passive locating. Active locating is when a tracer searches for a specific line using a direct connection or by emitting a signal. The tracer can be attached directly where possible or a frequency is selected (on adjustable receivers) which is then induced into the ground and reradiated by the utility used. This is the method most commonly used for maintenance or repairs where specific lines or pipes have to be detected. Passive locating involves tracing an area to look for unknown lines. The user would just scan the area looking for utilities that radiate or re-radiate frequencies. This method would not differentiate between lines but would clear an area for lines prior to digging or drilling.

Best Wire Tracer FAQ:

Q: What is a circuit tracer?

A circuit tracer kit consists of a transmitter, receiver and probe. The transmitter has a connection to one end of the circuit (electrical outlet) and transmits a signal that will travel along the wire that it is connected to. The receiver’s job is to detect the signal being transmitted on the circuit. The receiver is usually a handheld unit that can be adjusted to pick up different signals. When the receiver goes near a wire carrying a signal the user will be alerted with a noise or flashing light. The circuit tracer will also contain a probe that contains three different sensors. An electric field sensor in the probe, detects the end of the conductor, the differential field sensor decides the direction of the conductor above ground and the inductive sensor determines the direction of the conductor transmitting the circuit underneath the ground. The probe’s job is also to generate electrical energy (via a switch) which then determines the volume of power generated by the signal on the circuit. Electrical wires nippers

Q: How do wire tracers work?

Wire tracers work by relying on the target having an electrical charge or signal which is then detected by a receiver. Lots of electrical utilities transmit a signal when the lines are energized and lines often have different signals which helps to differentiate between the different lines. When a line does not have a signal, wire tracers can induce a signal along the line (using a transmitter) in order to locate it. The wire normally has to be metal in order for it to conduct a signal. The transmitter of a wire tracer sends out a signal and the receiver’s job is to detect this signal. If a signal is detected then the user will hear a noise or see a flashing light on the unit.

Our Top Pick

Our favorite product on the list was the Fluke Networks 26000900 Pro3000 Tone Generator & Probe Kit. We were massively impressed that the tone could reach 10 miles of cable and that the provided clear and precise wire tracing. Using special SmartToneTM technology, the unit creates five distinct tones so you are then able to isolate wire pairs too. The loud speaker on the probe ensures the tone is loud enough to hear through a number of materials such as drywall and wood. The kit comes with a nylon pouch that can clip onto your belt – we liked that little touch too!
