What Is the Best Borescope for Automotive Inspections

by | Feb 17, 2021 | Blog, News

Borescopes are specialized tools used to inspect and examine confined spaces. Many manufacturers make borescopes designed specifically for the purpose of viewing internal parts of a car. If you are interested in purchasing one of these specialized tools, you may get overwhelmed by the large number of borescopes on the market.

This guide will go through the best automotive borescopes available and also discuss the criteria used in selecting the right one.

How to Choose an Automotive Borescope

Automotive borescopes are essentially endoscopes used in the inspection of internal components. Many auto mechanics keep a borescope on hand to check for internal damage or defects in your car engine.

To perform their job correctly, automotive borescopes need to be small, flexible, portable and provide high resolution photographs and videos.

Probe Size

The size of the probe on the borescope is important, as it needs to be large enough to facilitate a camera, but narrow enough to fit into a confined space. For example, Diesel engines have very small tubes, and can accommodate only borescopes that are 6mm or less in diameter.

Camera Resolution

Camera resolution is another important factor when choosing a borescope. The camera on your borescope probe should be high resolution if you wish to see fine details in the images and videos it is capturing.   Most of the automotive maintenance borescopes will offer a CMOS image sensor.


A good automotive borescope will feature an LCD screen that allows you to view images and videos through the camera in real-time. You should ensure that the LCD screen on your choice of borescope is large enough to meet your needs, without sacrificing the device’s portability.

Battery Life

Battery life is also incredibly important for borescopes. Recharging the battery on these devices can take a while, so it’s best to go for a model with a long battery life.
