Go on eBay. Do a search. Type in "Endoscope". You'll find about 50 different ads for them ranging in size from 1 to 50 meters in length. (A meter is about 3 feet) They are cheap as snot.. about $15 or less including shipping, depending on the dealer. They are all made in China and are pretty much alike so expect about 2 weeks for delivery. Buy one with the 7MM head and about 2 meters long. The wire is very flexible so you need to tape it to something that you can stick into the hole and point it where you want it to go. (I used a length of 12 gauge solid copper wire that I stripped from some 12/3 non-metalic jacket wire).
Hooks up to any phone that has Android (NOT I-Phones) or you can hook it up to a laptop computer USB port (I use my Notebook) Works very well and sin e they have their own built in LED lights you'll be able to see just about every nook and cranny you can get to. I've used mine to look at pistons in my car engine, my boat's fuel tank, the bathroom sink drain (yuck) and several other impossible to get to area's. Trust me on this one. They work.
