If anybody has tried to snake wiring (like a CAT6 network cable) around an already finished house and your experience was anything like mine, you will know what a PAIN it is trying to get that cable through the wall, or a duct, and having no idea why it isn't going through, or what is obstructing it. I imagine this camera would be extremely useful to plumbers, electricians and general do it yourselfers. The image is very clear and there are attachments to put on the end of the camera to help with the job you are doing. One attachment is especially handy, allowing you to attach a guide wire/string and pull the camera through looking at where its going the whole time, or reverse, attaching a string to it while you push the camera through the opening and space your are trying to get through, and when at the other end, you can tie your cable to the string at the start and then pull it through. The camera cable is stiff which allows you to feed it through and push past/though some obstructions that would normally hinder a less stiff cable. The one thing that was difficult was sometimes the camera a cable were hard to manipulate when it was a good distance into the opening, but that is unavoidable really. The light is plenty bright enough and the camera a good enough quality that the light doesn't oversaturate things. On a lighter note, I suppose this would be very handy for spies as well. ;) This camera has worked GREAT for me and I figure I will continue to get good use out of it in the future. It is solidly built and is made from good components. The IP67 rating means completely dust proof, and water resistant in 1 m of water for up to 30 minutes, so for most uses this camera would see, that rating should be just fine for most. Really love this thing!
