The professional level tone generator and toner along with the LED that detects any kind of power overload and misreads not only improves accuracy and precision but also keeps the user safe from any kind of hazard.

It comes with two 9 volts batteries for the probe and the toner. These batteries can last up to 5000 hours, which is why this product comes under the heavy-duty category.

It comes with an auto power off feature which saves the battery life by turning itself off in case the user forgets to turn it off. This also improves the battery and product life. The low battery indicator LED helps you determine when you are going to face low battery problems so that you can plan ahead.

Extech Tone Generator And Probe Kit

This product is known for its quick identification abilities within a bunch of wires. Its abundant features also include detection, identification, and testing of phone lines which is why it is mostly used for that purpose. This product is considered an essential tool for installation of the phone line. The best part is, it is very reasonable and cost-efficient.

It has a non-contact amplifier which makes tracing the wire even easier. The output cables from the transmitter end in the plug which is an RJ11 phone connector. It has ideal features for phone line testing.

After it injects a traceable signal into the phone line and not only checks the polarity of the phone line but also works on the breaks and continuity checks of the phone line. Moreover, its sensitivity can be adjusted which eliminates the risk of any kind of false detection and also improves the accuracy of wire detection.

This product does not require the connection of the probe to different wires for detection rather it audibly detects the wire using its non-contact amplifier. The batteries require this electrical line finder are non-standard 9 volts batteries, one for the transmitter and the other one for the probe.

A complete kit comes with these batteries, a transmitter with RJ11 plug-in jack, a probe and some alligator clips for establishing a connection. Moreover, this product comes with a one year warranty which is great at this price. The product is known to work exactly as advertised once the manual is correctly followed.

With all that said, unlike Extech’s great circuit breaker finder, the quality isn’t as high as we’d like it to be. It’s hard to compete with tone generators that are 2-3x more expensive, but still. Go for an Extech if you don’t plan on using your tone generator very often. Otherwise, I would recommend a Greenlee, Ideal, or Fluke tone generator instead.

Buying guide

There are multiple tone generator and probe kits (i.e. electrical toners) on the market, each one feature different technologies and different level of accuracy and precision. Therefore, customers should consider a few things before investing in a certain electrical wire toner, so that they can find the best one for their job. These features are:


This is a professional name for the tone produced by the toner. Different toners have different kinds of tones; some have a single tone while others have a number of distinct tones with different levels. The maximum number of distinct cadence provided by an electrical toner is 5. You can also get the ones that provide a lesser number of cadences.


Some kits come with speakers that help you in tracing and identification of wires. The best of the toners provide their users with speakers that have adjustable volumes. These speakers can be used to detect wires in normal environments as well as in noisy environments. These speakers play an important role in the amplification of tone for accurate detection of wires.

There are multiple toners on the market that come with an earphone jacket for plugging earphones. These are mostly needed for noisy environments like construction sites.

LED display:

The LEDs is one of the most important features in an electrical toner. It tells you when something is wrong, or when you have detected the right wire or when you have to identify a different number of wires. For user’s convenience, some companies also add LEDs to notify of low battery power as well as to notify the overloading of the probe. These LEDs improve the accuracy especially when the user is working on a large bundle of wires.

Cablemap ability:

Most of the wiring mistakes and short-circuiting in the wiring are due to wrong wiring or mixing of wires. This can be detected when an electrical toner has cable map ability included. It can easily identify the wrongly placed wires especially when the wires are twisted. This feature makes the user’s work easy by eliminating the need of consulting a wire map. The common electrical faults can be greatly decreased by using an electrical toner with these features.

Apart from these features, the features that play an important role are the cost, the type of brand you are buying from and its reputations, the safety measures taken during production, the warranty and the battery life. A smaller battery life can make your life difficult rather than helping you with work.


For technicians and electricians, an electrical toner is a must have. Every product and company have their own rules of production and give a certain level of quality with the price range it offers. Keeping the products mentioned above in mind the Fluke Tone Generator and Probe Kit can be declared the best of the lot.

The price range it offers and the number of features included cannot be met by others. It can be used for any kind of wiring and can also deal with any kind of heavy duty work. Unlike other toners, it is not specifically accurate in a single kind of wiring rather it is master of all wirings.
