Borescopes are used for visual inspections where the area to be inspected is inaccessible by other means, or where accessibility may require destructive, time consuming and/or expensive dismounting activities.  Borescopes are mostly used in nondestructive testing techniques for recognizing defects or imperfections. A video borescope or "inspection camera" is similar to the flexible borescope but uses a miniature video camera at the end of the flexible tube. The end of the insertion tube includes a light which makes it possible to capture video or still images deep within chimneys, flues, heat exchangers, AC coils, drains, ductwork, above ceiling tiles and other dark hard to reach spaces.  As a tool for remote visual inspection the ability to capture video or still images for later inspection is a huge benefit. On many of these models, the video camera and flexible tube is submersible (for possible drain inspection when accessible) The borescoping will allow us to better diagnosis areas normally not seen by most inspectors.  We can then direct you in the right direction for further evaluation and possible servicing or replacement.
