Bought a $300 bore scope for a stubborn bleed air leak, and it paid for itself in a day.
We had a 737 with a leak we just could not find, even after pulling a bunch of panels. Boss said to just keep looking the old way, but I went and got a cheap digital bore scope on my own dime. Snaked it into a duct behind the APU and spotted a cracked weld in about ten minutes. Saved the crew a full shift of extra work. Anyone have a favorite tool they bought themselves that the shop didn't want to spring for?

My buddy at the cargo line swears by his personal thermal camera for finding air leaks. He found a cracked duct on an MD-11 that was invisible to the eye. What kind of bore scope did you end up getting?

I grabbed a Teslong borescope from Amazon for like 80 bucks a few years back. We had a similar ghost leak on a CRJ and I was tired of pulling the whole interior apart. That little camera found a split in a bellows coupling behind the rear galley in maybe twenty minutes. The shop still uses the old mirror-on-a-stick method, but my cheap tool gets passed around all the time now.
