After searching the forums I haven't see much about mounting the GoPro on a helmet using the adhesive mounts. I was wondering how many GoPro users here have used the adhesive mount on a helmet when wakeboarding?
I have used the combination of a head strap mount under my Shred Ready helmet. It seems to work. The only downside is wearing all that gear.
I crash like the best of them...so i can vouch for the mounting staying put. The head strap though is not made to be on the outside of the helmet, it will come off. I just attached a floating lanyard to the gopro in case it does come off my board, helmet or vest. The 3m adhesive works great if you clean the surface well.
