also using a hero 7 black, works great, 4k, battery lasts a long time.  Finally settled in on a little gizmo a 'stick pic' for about $17 to shoot from my hiking pole, went through several iterations of connecting to the poles, this is by far the easiest, surest, lightest, option.

The gopros go on sale seems like every time they upgrade, so you can get great deals.

I use adobe premiere elements on the vids if I want to modify lens curvature distortion or work on the colors.

good luck
