Can you use a gun borescope as an endoscope or visa versa?

You can use a gun borescope for non-gun inspections, but they are optimized for looking inside a gun barrel with a focal distance of ½ to 1 inch, so it won’t work for all applications. The side-view mirrors are best for up-close surface inspections and won’t have as wide of a field of view as our dual-lens camera probes. Gun borescopes are typically rigid probes because that makes them easier to handle and turn inside the barrel, but it’s not a requirement. Our regular inspection endoscopes are suitable for gun inspection so long as they fit down the barrel. Single-lens camera probes will work the best because they include a right-angle mirror accessory. The right-angle camera on our dual camera lenses will NOT work well to inspect the flutes inside of a rifle barrel because they usually are too close to the lens and the focus will be blurry.

Why are there three mirror accessories included with my borescope & why does one have a “red cap” on it?

The side-view mirrors give the user a 90-degree side-view when inspecting inside gun barrels. Since they are so small, they are also delicate and can bend if, for instance, the borescope falls onto the ground. We provide extra mirrors because damaging or losing these small mirrors is a common occurrence. The mirror with a red cap on it has a special angle that should help reduce glare - if you are experiencing issues with glare in your mirror then try using the red cap mirror and see if your view improves.

Do you make other mirror sizes?

Yes, you can find the 5-Mirror Set on our accessory page. Teslong borescopes usually come with a 0.20-inch diameter mirror to fit .22 caliber or larger barrels. While these mirrors will fit in larger barrels just fine they will have some slop and move around, which can affect focus and image quality. To get the best focus and see the largest area we offer the 5-Mirror Set designed to inspect .22, .243, .30, .38, and .40 caliber barrels.

What is an all-in-one endoscope or borescope?

An all-in-one endoscope or borescope is one that includes its own screen and does not require another device to function. All-in-one endoscope cameras also have their own rechargeable battery and a memory card to store photo and video content.

What is a USB endoscope or borescope?

A USB endoscope, or borescope, consists of a camera probe and USB cord. This type of device must be plugged into a smart phone, tablet, PC or Mac computer to work, it doesn’t have a battery or memory - photos and video would be stored on the device it is plugged into. USB devices are not usually compatible with iPhones or iPads because iOS devices do NOT have USB. If you have an iOS device look at a stand alone or WiFi compatible device.

What is a WiFi endoscope or borescope?

WiFi endoscopes and borescopes use a WiFi transmitter to send their signals to your smart device, where they are viewed and stored using an app. Endoscopes and borescopes with WiFi transmitters are compatible with iOS (Apple iPhone & iPad) devices. They will also work with Android devices and since they plug into the WiFi transmitter with a USB plug they are also compatible with Apple OSX and PC computers.

How do you use an endoscope with a screen?

An endoscope with a screen is very easy to use. First, make sure the device is fully charged. Next, install the camera probe into the monitor - it will either thread onto the monitor or it will plug into the monitor. Press the power button for a few seconds and the screen will illuminate. Use the Mode (M) button to switch between photo, video and viewing modes. All you have to do now is insert the camera probe into something you are inspecting and record photos and video by pressing the camera button.

What is the difference between an endoscope and a borescope?

Generally, “endoscope” is a medical term for a surgical device, but we frequently call our products “industrial endoscopes” to avoid confusing them with medical endoscopes. Teslong does not make any medical-grade surgical products. “Borescopes” is a term that is basically interchangeable with “industrial endoscopes,” however we refer to all of our firearm inspection cameras as “borescopes” and the rest of our inspection cameras as “industrial endoscopes.”

How much of a difference does the screen size make in a stand-alone inspection camera?

Although the screen sizes and resolutions are different on some of our endoscopes, they all record video at 720p resolution or higher. The resolutions you see on the screen can range from the smallest 854 x 480p resolution, 4.5-inch screen up to the 1280 x 720p resolution, 5-inch screen. Obviously, larger screens are going to give you a better view of what the probe sees so if you need an inspection camera to perform on-site inspections and solve problems right away then you’ll want the biggest screen. If you are more interested in the recorded video and photo content, then a smaller screen should work just fine.

What is the difference between dual-lens probes and single-lens probes with mirrors?

Telsong’s camera probes typically are available with either a single-lens design, plus a right-angle mirror, or they are available with a dual-lens design. The single-lens-with-mirror probes are less expensive, and they are better for looking sideways at surfaces up close. Most commonly, this benefits Teslong’s gun borescope customers. If you use a dual-lens probe for this type of application the right-angle lens will actually be too close to the gun barrel surface and sharp focus will be impossible. This is why all of our gun borescopes use a single lens with a mirror instead of a dual lens. For most other applications, like looking down a spark plug hole into the combustion chamber of a car engine, the dual lens design typically works better and gives a wider field of view.

Who makes the best borescopes?

Teslong has been making gun barrel inspection cameras for over five years that started after we were approached by a ex-military sharp shooter looking to confirm his precision rifle cleaning process. We make stand-alone, USB, and WiFi devices to inspect rifles, and pistols with rigid or flexible probes.
