I just recently got the 8, haven’t used it for this specifically yet. Been hermitting for obvious reasons. The 8 also gets you into the new battery for longer life and no need to buy the new one!!
There are sooooo many attachment types it’s just ridiculous! There is chest, head, backpack, waist, and others like a body board and anything else you can think of. That alone is enough as far as location for the device.
I love the fact you can view your shot live on your phone with the app; can’t use a watch unless you use GoPros watch. The stability has been amazing! So, attached to something there may be some jumping but that’s while jogging! Still testing possibilities.
I actually used the body board one this past summer to catch waves (cheaper, 60$ knock off) and I couldn’t believe how stable.
