Has anyone tried exploring an elevator shaft by lowering a tethered camera into it? There is a You Tube video in which someone exploring an abandoned hotel in Gary,IN is lowering a Go Pro into an elevator shaft. Also I have a video just posted on YT of me lowering my camera into the elevator shaft along with an LED light taped to the end of a 35mm preview film mentioned on YT in the description. https://www.youtub...atch?v=Gcx7n2KyYPo
