Endoscope Camera with Light, 1920P HD Bore Scope Borescope with 8 Lights, Waterproof 16.4FT Semi-Rigid Cord for Pipe Inspection, Industrial Endoscope for Phones(Black)

This ended up being very close to the winning idea. Your idea to look through the EMT was sound, but the EMT deflected more than it's 1/2" diameter (over the 10' stick) so my view was blocked. I ended up buying one of those cheap endoscope cameras from amazon and put that into the EMT and was able to steer right to the hole and voila, done in 10 minutes. https://www.amazon.com/dp/B0C4FBM6GV?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
