Articulating borescopes are complex and powerful devices that allow you to observe the detail of objects at a level that would normally be impossible with the human eye alone. Whether or not this statement rings true for you has everything to do with whether or not you are choosing the appropriate option. If you're looking for a new borescope, here are just two factors to consider to ensure you're paired with the right unit.
Flexible Vs. Rigid
A flexible borescope is one with an extension that can be manipulated. A rigid extension is one that is in a fixed position and does not move. When making the determination as to which style to choose, you want to determine whether or not image quality or maneuverability is most important. Rigid extensions offer a crisper, higher-quality image. However, since the extension is fixed, it can be a challenge to get it to fit into tight places.
On the other hand, flexible borescopes can be manipulated to fit into a variety of spaces and configurations; however, this versatility isn't free. Some of the quality of the image production is often lost as a result. Given this information, you can't exactly say that one option is better than the other. Instead, your decision should be based on your anticipated needs. If quality is most important for you, then a rigid extension is best. However, if maneuverability is paramount, a flexible extension is better.
Field Of View
The next important factor to consider during the selection process is the field of view of the borescope. Borescopes range from narrow fields of views to wider fields of view. Similar to the extension style, one option isn't necessarily better than the other, but instead, your decision should be based on how you plan to use the device.
If you generally plan to use your borescope on objects that are going to be placed a considerable distance away from the end of the borescope, the narrower the field of view the device needs in order to produce a clear image. However, the shorter the distance between the end of the borescope and the object you're viewing, the wider the field of view necessary to produce a clear image. Choose a field of view that will offer you the best clarity.
Choosing an articulating borescope isn't a process you should take lightly. The more effort you put into making a selection, the more use you will get from the unit and the better it will perform so make sure you are choosing wisely.
