Yeah yeah we know, the joke almost writes itself: colonoscopy at home! (we kid we kid, do NOT do anything stupid). But there are other interesting and dirty places to explore: do you want to know what is in that dirty pipe? Or any hole for that matter? Youi can peak into objects, you can peak into machines, pipes, close up of your animals in water. Really, endless options. With the 11.48 ft long cable you can even get closer to these dangerous insects and make a video.
