We used one for quite a few years in supermoto,RMMM and the MRA. They hold on quite well. I would still tether it somehow if you can. We only lost ours twice. Once at a minimoto race and they let us look for it during lunch. We found it and had some good footage of sky ground sky ground and then 20 minutes of face down in the weeds video. We also lost it at an MRA race at HPR when Adam crashed his 250. The corner workers were nice enough to pick it up when they were picking up all of the other pieces of the bike. Unfortunately, it took a direct hit in the crash and came out of its case and no longer works. They are a great learning tool and we miss ours.
