Even for DIYers with excellent eyesight, there are certain barriers through which they’ll never see. Whether it’s an engine block, a pipe, a wall cavity, or even a crack between two surfaces, getting a good look at damage or a fallen item in a hard-to-reach spot can seem impossible—unless there’s a borescope nearby.
A borescope is essentially a tiny camera on the end of an arm. Users can place these inspection cameras into tight areas for a better look at what’s causing the issue, helping them to formulate a plan on how to fix it. There are a variety on the market, each with all the features required for specific uses.
While assembling our list of top picks, we consulted John Mazzuca, a custom home builder and the owner of Gambrick in Point Pleasant, New Jersey, for his professional opinion. Mazzuca agrees that these tools should be used for areas that are “too small, too far away, or are obstructed.” He went on to say he uses them “to look into pipes for clogs and damage, to inspect inside wall cavities, under cabinets, [and] inside cracks, [and also for] mold inspections, pest inspections, termite inspections, [and] to look under tight crawl spaces.”
For a better look at how to choose the best borescope, keep reading this guide to find out some of the top features to consider, and check out the list below of some of the best borescopes on the market.

- ALSO CONSIDER: Depstech 1080P Wireless Snake Camera
How We Chose the Best Borescopes
Putting together a list of the best borescopes is tough work. There are many models to consider, so we needed to be as discerning as possible. Mazzuca points out that “the quality of the camera is very important, as higher resolution cameras yield clearer images, making inspections much easier to do and more accurate.” Though the camera resolution is very important, Mazzuca says that the light is also very important. “Every borescope should have an LED mounted on the tip so you can see in the dark, but some have better lights than others.”
While we conducted hands-on testing, we called upon our experience as DIYers and time spent using borescopes on various projects to determine which features we thought would be important. Next, we performed extensive product research to compile a list of borescopes that we felt met the standards of most home users.
Finally, we compared each borescope’s price to its features to ensure each one offered enough value. We discarded any models that didn’t make the grade and chose only the best borescopes for this guide.

What to Consider When Choosing a Borescope
While the features and capabilities of many cable-mounted cameras might seem pretty straightforward, there are a few points to consider before selecting one. The following are some of the most important considerations to keep in mind when searching for the best inspection camera.
Rigid vs. Semirigid Cable vs. Flexible Cable
There are three main types of borescope arms: rigid, semirigid, and flexible cable. They each work a bit differently, but a bit of background will help when choosing among the three.
- Rigid borescopes have strong, stiff arms. They’re excellent for straight and vertical inspections where a flexible arm might not do the trick. However, they aren’t able to bend with curved pipes or snake around corners, and they can be tough to store.
- A semirigid borescope has a bit of flexibility, but it will also hold its shape. This cable type allows for bending around corners, but it will also stand vertically for overhead inspections. It combines the best of the other two types.
- Flexible cable borescopes are able to snake around corners and reach anywhere the users can place them. However, it can be hard to advance one through a pipe without the assistance of an additional pole to push it.
Camera and Image Quality
The camera and image quality are huge factors in considering a borescope. The device needs to offer a clear image, particularly when inspecting a very small space like an engine cylinder or plumbing fixture. It’s not uncommon to find cameras with multiple megapixels, offering resolutions of 640 by 480, 1280 by 720, 1600 by 1200, and 1920 by 1080.
And to help get those sharp images, many borescopes feature built-in LED lights that can illuminate dark spaces. This can be significantly helpful with plumbing pipes and wall cavities where using an additional light source isn’t possible.
Borescope cameras also come in varying diameters, and the size may determine which option to purchase. For instance, some larger borescope cameras might not fit in smaller spark-plug ports, while very small inspection cameras might not be as durable as needed. Sizes for DIYers generally range between 5 and 15 millimeters.
Power Source
Almost all borescopes are battery-powered aside from some industrial endoscope models meant for long-term inspections. However, there are several types of batteries, including replaceable, rechargeable, and built-in rechargeable.
Borescopes with replaceable batteries typically use 9V or AA batteries, and users will have to keep a few extra in their tool kit to make sure their borescope is always ready for the next job.
Rechargeable batteries are typically from brand-specific battery lines such as the 12V or 20V batteries used to run cordless power tools. Built-in rechargeable batteries stay inside the borescope at all times, and the user simply plugs a charger into the unit to refill drained batteries.
Built-in Screen vs. Wi-Fi Connection vs. Plug-in
For a borescope to be effective, the user needs to be able to see what’s going on in real time. To accomplish this, most models have built-in screens that display exactly what the camera is seeing. These models require very little setup time, but they can be bulky and the screens aren’t always top-notch.
However, some models offer Wi-Fi connectivity in place of built-in screens. These models emit their own Wi-Fi signal, and users must download an app and connect to the signal to access the camera’s view on their smartphone’s screen. These units are streamlined to carry around, but they can be more challenging to set up.
There are also plug-in borescopes that connect directly to the smartphone with a plug. The user must simply plug in the borescope and then open an app to use the phone as the camera’s display.
Additional Features
There are some additional features and accessories that users might want to consider. The most helpful include hooks and claws that can grab items blocking plumbing pipes. Other features include an LED light that makes it easier to see in dark spaces and a bag that helps with transportation and storage.
Also, some folks might want to look for borescopes that can record their entire inspection on memory cards. Others might appreciate mirrors that connect to the end of the camera, allowing the user to see around corners, or magnets that can collect small metal items like keys or fasteners that are unreachable by hand.
Finally, consider choosing a water-resistant borescope. These models might offer resistance ratings such as IP67, which indicates that it will resist water and dirt penetration.
FAQs
The above might be a lot of information on the best borescopes, but the picture still might not be entirely clear for every shopper. The following includes answers to some of the most frequently asked questions about borescopes and inspection cameras.
Q. Can a borescope view side to side?
Some borescopes have side-mounted inspection cameras that allow the user to see 90 degrees from the tip of the cable. For those that don’t, many come with mirrors that can do the trick.
Q. Can I scratch my borescope?
Yes, borescope lenses can scratch. A liquid scratch remover meant for watches or eyeglasses can help.
Q. What else can I use a borescope for?
A borescope’s main function is to inspect pipes, but with a hook attached, it may be able to remove clogs or retrieve dropped keys. With the magnet, it can pick up dropped hardware or even metal shavings when necessary.
Q. What’s the difference between a borescope and an endoscope?
The term “endoscope” is often used interchangeably with “borescope,” but endoscopes are actually medical tools. Borescopes are suitable for mechanical use only.
Q. How much does a borescope cost?
Most borescopes for DIYers cost between $50 and $250, but they can be much more expensive.
