Honestly, how expensive is a borescope these days?
I picked up a cheap USB one to look at my garbage disposal’s interior a while back. I think it was something like $50.
Now, I can believe that this jet engine one is fancier, but unless it images outside the visible spectrum or has to be inserted into a recently-running, hot engine and survive hot temperatures or something, I doubt that it’s that much fancier. There’s only so much that a CCD and light on the end of a cable can do.
To view the coking, you really need a very small and long endoscope with it. You really didn’t get that with the $50 borescopes back then. Most of them at that price point wouldn’t allow change outs either. Now you can get them with changeable endoscopes, decent video and recording of course fairly cheap.
