Borescopes (or boroscopes) are optical inspection tools which consist of a hollow tube with an eyepiece and a lens at opposite ends.
While borescopes are produced in many forms, all devices include a hollow tube, a light source, an eyepiece (which typically contains a means for magnification), and some form of relaying an image from the end of the scope to the eyepiece (often optical lenses or a video camera). They are primarily used for visual inspection...

Applications and UseTop
When we drill open safes, we need to see the internal workings to open the combo without doing a lot of damage, thus saving us a lot of repair to only fix one hole. Also to find wiring & pipes in walls when we are installing safes in walls. We also use borescopes to work in tight confined spaces and inside combustion chambers in our race car engines to check for signs of detonation in the piston tops or combustion chambers and to inspect for cracks in cylinder walls for coolant leakage.
Our video borescopes are used in many applications where a person needs to inspect or find something in an area where they can't physically fit. We have both small and large diameter video products. They cover a wide range of applications and industries where they are used: aerospace, metals & casting, oil & gas, power generation, transportation and security. Personally, I used them to find leaking plumbing in between floors and behind walls.
Inspecting weeping tile for blockages, and chimneys for finding out the cause for filling the building full of smoke. Inside stone walls to inspect the condition of mortar. In joist spaces for blocking when installing sprinkler systems into existing buildings.
I have used these for looking and seeing invisible joints for leaks under the bonnet or under the car. Snakes under the furniture in tropical countries. Viewing visible defects in Test Instruments PCBs in situ, without opening the Chassis.
Full featured portable Videoscopes of weight about 1/2 KG with screen size of at least 4", measurement system, interchangeable videoprobes, probes. The main thing I want to see is a videoscope with 3D view of image for accurate measurement & ability to see deep inside the object like tomography system.
Digital image/video storage. Simple easy to use measurement, bright clear optics, LED or laser illumination, flexible, yet very durable insertion tube, able to work in a high temp environment, and a very small portable platform.
If inspecting pipes you need cleaning rags to wipe it off before putting it away. So some kind of cleaning kit should accompany the unit on each job. Spare O rings for connections. Additional source of light is good to have. It is a good idea to know what the interior of what you are looking in should look like. Markings on the cable to determine the length that the unit is down the drain is a good idea.
The Borescope should be suitable for your application - consult manufacturer. Accessories specific to your applications should be purchased . The borescopes are sensitive and fragile and store these in the boxes and carrying cases provided. Do not use acid or corrosive substances to clean tip - only Isopropyl Alcohol. No Acetone, petrol or chloroform etc...
Currently, price is the driving force due to the pressure on budgets. Do remember that price alone as criteria might not give you the instrument and result you need. There is big risk you might pay more at a later point in time or even miss important details, creating much higher costs.
Spend the money up front. The money you are trying to save up front will be lost in short order from the frustration you will experience trying to get by with inferior equipment and it will cost you in down time not finding problems that truly are present just not obvious. Shop around and make sure that the scope's functionality isn’t just something they write about but is incorporated in to the product you are purchasing.
For users - please use with care as these are fiber optical instruments, your mishandling can lead to a big repair cost. If handled properly, these instruments have almost indefinite life. For buyer - first of all they have to be clear about the application where the Borescope, Fiberscope or Videoscope is to be used. This helps us in selecting the right product for the application.
Research the correct one for your application, and think of other potential uses that it could be used for. For example, one fitted with a screen allows you to easily view the item being inspected, no need to keep one eye pressed to the scope which can sometimes be very awkward. A screen also allows others to view the item which is invaluable for training.
