I was watching some of Dave Mcloed's vlogs and like the way he has a stationary camera ti film his attempts. I was thinking this would be a good way of reviewing my own climbing so I can see where I need to improve.
Does anyone have a good suggestion for an inexpensive camera that would work? A smartphone battery won't last, and I worry a go-pro fish eye lense might not give good results.
Any suggestions much appreciated.
