Been putting off buying one for ages, watched a guy borrow one from the next hangar and find a cracked baffle in 10 minutes. Pulled the trigger on a decent one from Snap-on last month, found a loose exhaust flange on a Cessna 172 this morning that I woulda missed with a mirror. The customer literally watched me use it and asked if he could take a photo. Anybody else got tool purchases that seemed steep but turned out to be worth every buck?
Did you try the simple stuff first, like checking the fuse box or swapping out bulbs? @the_hayden, I had the same issue last year and it turned out to be a loose wire behind the switch, took me five minutes once I stopped overthinking it.
