New Go Pro owner

Hey there, I have just got a Go Pro hero 3+ black edition. Been playing with it before my next sledding trip.. My questions is does anyone have advice for the best snowmobiling setting to use. Ie battery life , picture quality, and so on. I have the battery back pack and 2 spare internal batteries. I plan on using the chesty mount and also a mount on my helmet..I've played with the 2.7 and Protune on and the picture is amazing, only bummer cannot be viewed ipad or iphone....
Any help anyone is willing to offer will be greatly appreciated
