Cost-effectiveness
Using a Flexible Borescope can be more cost-effective than using other NDT methods. This equipment costs next to nothing to set up, and is simple enough for most technicians to operate. 

Flexible Borescope can also be rented for on a daily basis or weekly basis. This makes them an affordable option for oil and gas facility managers that wish to investigate a suspected crack or defect.

Portability
Flexible Borescope are among the most portable inspection devices available. Most models weigh only a few kilograms and can run on batteries. This makes them useful for conducting inspections in remote areas where other equipment cannot be transported.

Inspections in Real Time
Flexible Borescope inspections are also favored due to their ability to view and display internal components in real time. Operators won’t need to wait for the equipment to collect data and then create an image at a later time. The display mounted on these devices allows you to view the image as the camera is passing through a pipe or a piece of equipment.

This enables you to spot any defects or imperfections that could compromise the safety of the pipe or equipment, and then maneuver the probe camera focus on it. This may seem like a relatively basic advantage; however, it can be difficult to perform similar inspections using other equipment.
