It's an older GoPro (Hero 7 Silver) that I have mounted on a chest strap, so yes right in the sternum area. I tried using a helmet mount but discovered I look around too much and it made for distracting videos.

My brother gave the GoPro to me as a gift a little more than five years ago. He was hoping he could see videos of me getting attacked by geese. I do get attacked by geese on occasion, but the joke is on him because the geese attack from the side where the camera won't pick it up.
