Nasher, worth making sure anything attached to the head (eg the mirror) is firmly fixed onto the borescope head so it does not become detached during use and remain inside whatever you are inspecting.
Borescopes are used quite a bit to inspect gas turbines, and have seen a few aircraft engines which had to be removed and sent to the shop because interchangeable heads had been released from the ends of flexible borescopes, or even complete ends cut off them because an engine shaft was rotated and a blade cut the end off.
