I’ve got a Rigid (scope that is), I love it. I use it all the time and is great for exploring situations and finding hidden problems. Got mine at HD for $199. Plus you can get extensions which I believe can go up to 15’ (can’t remember the exact #)
The big problem is my Ridgid is that I ***can’t ***get the image into the report except by taking a picture of the Ridgid’s display screen (very difficult, as you usually need one hand to hold the display and one hand to hold the flexible probe and one hand to hold the camera). That’s why I posted the link to the Testo unit above.
I’ve used the Ridgid for a grab-bag of stuff - everything from checking the type of gas connector on a dryer to determining if the material of a duct in a slab was Transite or clay tile (it was the latter).
I just purchased mine through Professional Equipments also bought the 3’ extension for various areas where I wouldn’t be able to reach, It does come in handy. It has LED lighting infront with the viewer for a clearer image.
I’d say go for it.
Good luck…
Check around for prices, you might save a few dollars on it. It comes with a black zippered case very durable, and the batteries
I have done asbestos transite removal in slabs during demolition of on-slab homes. I also use my scope to look behind siding. I see some homes that have alum. over asbestos siding.
