Olympus Borescope
Fiber optics are the next big thing and olympus borescope has fiber optics unlimited. The idea is to attach a small camera or mirror on the end of the long pole so that you can look around corners or anything else that may be obstructing your view. Home inspectors use these most often when looking for mold or asbestos damage. This is because they can make a small hole to stick the scope into and look around without having to crawl under the house or knock out walls to inspect any potential damage due to any kind of bugs or mold.
