DAE skip the camera and just run a mirror up the flue?
Watched a guy on a Facebook group tell a new sweep he needs a $400 camera setup before he books any job, and I think that is backwards. I have run a simple mirror and flashlight on about 600 flues over 7 years in Dayton, and I catch the same cracked tiles and bird nests he does. What are you all actually using to inspect, and did a camera ever find something a mirror missed?
