Yes the Voyager is made by ATS, and there is a sale right now but even on sale it’s 800.00. Here is a link to it, and they have a video showing it used for a valve inspection. Also you can click on the “see specifications” link and see the manual and all that it comes with. It is a lot of money for just occasional use, but it comes with a lot of accessories that make it do almost any inspection job. The camera lead (wand) is super flexible, which is primary difference with lower cost cameras which have a more rigid wand. There is also an accessory rigid holding shaft (tubular sleeve) for when you want to support the wand rigidly over a distance. I’m very happy with it, but for the price, the VEVOR that David posted looks like it gets most jobs done at a fraction of the cost.
