[Jolly Amaranto]

I use mine for a "dash cam" on my bicycle. Occasionally I catch something cool on it when a crazy driver does something strange.
The old family property has a hand dug well that is over 100 years old. I wanted to see what was down there so I attached the GoPro to a plumb bob and did an underwater exploration of the foot valve and siphon jet. I had to strap a 300 lumen water proof flash light to the rig to see much.
