I can see using it for checking out inside motorcycle engines... just pull a
sparkplug and poke it in. I've heard that there are 'borescopes' that are
used for checking out the inside of gun barrels... looking for pitting or
worn rifling I guess.
One place I worked we had a run of circuit boards made with defective
IC's... unfortunately it wasn't discovered until the boards were out in the
field and failing. As these were mil-spec PC's the government wasn't too
happy about it. As the PC board was inside the case -and- covered with a
sheetmetal shield soldered in place, it was determined that the best way to
determine if the PC had the defective part was to use an "inspection scope"
through a small opening uncovered when a side panel was removed. This
inspection was done using a special borescope that would fit through a hole
~4mm, and carried its own light in there too. The cost of this was many
thousands, sending an engineer and equipment all over to do inspections...
and a big lawsuit ensued over who got to pay. My testimony was that the IC
supplier claimed to sell us one thing but shipped another... I think they
lost to the tune of ~$300,000 on that suit.
