don't have it yet, but i'm getting it for christmas, i think it'll be much easier to use + enable me to use it while not wearing my helmet ...
i think it'll be worth the money, even just for those deep powder days, if you film deep days with a chestmount you'll get a ton of whiteouts which is awesome !!
i have pretty much the same question so ill post it here
is the chest mount better for powdershots cuz im going to bc this year and i feel like the chest mount would get covered in snow so it owuldnt film anyting whereas the head mount wuold be fine
