This is a ring which fits on 1.25in pvc pipe. It also has four holes for securing a camera to the center for recording. I had something large at the bottom of my well which made it impossible to dig deeper. This allowed me to find out what it was. I used a gopro secured with fishing line. The outer most 12 holes are for 5mm LEDs. There are also hole for securing ring to PVC pipe. It worked WELL lol.
