Buying Guide: How to Choose a Chainsaw Tachometer?

You should always look before you leap, which is, in this case, checking out the features prior to purchasing a tachometer for your chainsaw. If you do not want to end up with a dead-end machine, then we suggest you go through the informative buying guide.

The Quality

Built-quality is one of the most crucial features of a tachometer. Let us be frank, slicing down woods is not the most hygienic job. Therefore, you and especially your tachometer will be exposed to debris, wood dust or water, and much more.

On the other hand, the tachometer will also go through a lot of vibration due to the chainsaw. Thus, built-quality is imperative as your device needs to come out victorious even after endless tortures.

So, before purchasing a tachometer, check if the little buddy can handle the effects of the environment.


Okay! Let’s get down to business. Previously we have mentioned that a tachometer can read the RPM of an engine. It can be the engine of a chainsaw or anything else that rotates.

However, you must know that there is a specific limitation, even for the best tachometers. This limitation of reading the RPM is called the range of a tachometer.

Usually, such devices can read up to 10,000 rotation per minute, which is more than enough for most machines. Nevertheless, you must know the limits of your tachometer.

Having a high range is useful when you plan on using the product on different machines.

Power Capacity

Another crucial aspect that you must look before buying a tachometer is its power capacity or battery life. Two models are most famous on the market.

The first one is used with cordless chainsaws, and the second one is often seen in wired saws.

The best tachometers on the market have an exceptional battery life. They can run for a lot of years (some may even live longer than your chainsaw).

Thus, we recommend you to check the power capacity of a device before spending your hard-earned cash.

Digital Memory

By memory, we do not mean that the tachometer will remember your homework. Instead, it is a feature that enables the device to memorize the minimum and maximum RPMs of a specific period.

Moreover, the digital memory will save every data even if the batteries run or switch out suddenly. Hence, your data will always be safe and secure inside the device.

On the other hand, if you want to observe the performance of your chainsaw, this feature can be a blessing for you.

Final Thoughts

There is a fine line between decent and excellent work. To reach excellency, one must use everything in their arsenal. Hence, you should not saw woods without using a tachometer.

A chainsaw tachometer is not only optimal for accurate cuts but also useful to know about the condition of your saw. You can check the RPM of your machine for precise slices, which is crucial if you want the best results.

On the other hand, you can check the maximum RPM of today and compare it with the readings of yesterday. If it’s not the same, then you will know that your saw is not in its finest shape.

In our review of best chainsaw tachometers, we have tried to cover almost all the things related to tachometers. We hope our guide will help you to buy an optimal device that will satisfy your woodworking needs.
