The Good
The Bad



Some of the products that have been introduced to the public are the results of scientific achievements and military or industrial demand, and that is also the case for borescopes (also called boroscopes).

The borescope was first used to inspect interior bores of large guns. Then, it went into industrial use for remote visual inspections (RVI). The device became more complex and different types were developed, but the generic term borescope still covers all of them.

The tool now serves a variety of industries and applications, from weaponry and law enforcement to casting, aerospace, aviation, sanitation or electronics and automotive.

To serve such different purposes, the borescopes have been adapted by holding various lengths, diameters, and functionalities. These are the types of units you will find on the market, and you’ll be able to choose the best borescope for the money if you use the guidance and address your current needs.

Rigid borescopes

This is the most popular type of borescope and consists of an optical device attached to a straight tube.

This type of borescope is cheaper because it has a simple design and uses more economical materials. The small lenses are not all that expensive, and the design is less sophisticated. This means if you’re looking for the best cheap borescope, you should probably be looking for this type.

They are also easy to use and offer high-quality images since the view is unobstructed, in a straight line. However, the range of its uses is limited, because of the inherent lack of motion.

They’re good for checking car parts, gun barrels, or straight pipes, or small parts that require very clear high-resolution image. You might find the best automotive borescope in this category.


Semi-rigid borescopes

These are considered an improvement of the rigid borescopes because they are bendable and have the best performance is spaces that don’t offer much room for articulation. Semi-rigid borescopes are more durable thanks to technological progress, and even though they have a lower image quality, they still have the advantage in situations that require more that just a rod.

Some of the borescopes that fall into this category are also classified as fiberscopes because they come with semi-rigid articulating properties.


Flexible borescopes

As designated, they have a twisting tube that gives you the possibility to twist the probe and go through curved pipes, ducts or vents. They tend to be in advantage wherever space limitations ask for instruments that can overcome steep angles and curves. High mobility allows them to enter small cavities and turn 360 degrees.

The flexible borescopes give the investigator the possibility to cover large areas and distant parts of the targeted objective. The depth and accuracy are increased and the viewer reaps all the benefits.

Since the flexible borescopes can cover straight lines as well, operators that need access to both types of spaces can save money purchasing just this type of borescope for both inspections.   

Most of the flexible borescope have great image quality because they could blend in the latest technologies, like small video cameras and LED lights.

The downside consists in the fact that it’s quite difficult to maneuver them, a challenge inexperienced users will find truly hard to overcome. They are also much pricier than the traditional ones, because of the costs their technology involves.

Semi-rigid and flexible borescopes contain two other varieties of these instruments, the fiberscopes, and the videoscopes.  


These borescopes relay the image that forms in the lens through a bundle of fiber optics to the eyepiece or display. The image quality varies in correlation with the number of fibers and their transparency, but the image is not always accurate.

Fiberscopes are less durable since you can’t repair them. Once a strand is broken, the image will suffer pixelation and eventually become unusable.



The best borescope reviews recommend them as the best thing on the market. If a complete list of top borescopes were to be compiled, then most of them would fit in this category, including the best USB borescope.

That’s because these are the ones that incorporate the latest technological advancements.They have Wi-Fi technology, use iPhone applications and much more.

Essentially they use small cameras and light to capture images and then carry the video signal through the insertion tube to the video processor and display. These probes have high-resolution images and provide valuable help in a number of applications.

Security and law enforcement, visual inspection of industrial equipment, turbines or boiler systems are among the major beneficiaries of these instruments.

What is a borescope inspection camera?

A borescope inspection camera is a name under which a video borescope or videoscope is most commonly known. The borescope inspection cameras are systems that combine a small video camera placed at the tip of a probe with the LCD device on which you can watch the video or photo taken by the camera. Be careful though not to confuse them with the endoscopes used exclusively for medical purposes.

Instead of placing a lens at the tip of a rod, we know have the possibility to put a small camera at the end of a flexible tube. This way, one can have visual access to places that he couldn’t normally reach, like pipes, tanks or vents.

The LCD on which the images are playing usually has a joystick or buttons with which you can maneuver the camera through the tight space that is being inspected. It can also feature WiFi signal to send the images to a computer or phone or pad.


How does a borescope work?

Borescopes are optical instruments that have an objective lens at the far end of a rod or probe and an eyepiece at the near end and are used to inspect places that we can’t reach, not without causing unnecessary damage.

The lens or camera that captures the image of the object or surface in front of them is connected by an optical system to the eyepiece. The image is relayed to the eyepiece by using lenses, in the case of rigid borescopes, or fiber optic bundles when using flexible borescopes.  

The eyepiece that magnifies the image so that it can become visible to the eye. To capture a good image in dark corners and tight spaces or cavities the borescopes use illumination with flashlights, lamps or LED bulbs.

Recent developments enable borescopes to send the images of video recordings directly to you iPhone, or PC by using the built-in WiFi technology.
