Deep breath
surfing. gotta have the deck mount and the backdoor floaty.
4wding gotta have the suction cap mount to put it on the bonnet or roof
Scuba diving gotta have the wrist strap housing. scuba diving/wakeboarding/snowboarding gottta have helmet or chest harness.
Motor bike/mountain bike gotta get the handlebar mount . then ya need the tripod adaptor and the handle mount just because. then you need battery packs and then ya need another go pro so you can shoot from different angles. And you need the frameless mound so you can do time lapse stuff and charge the camera at the same time. Then ya have to buy a big arse padded case to store it all in. Only reason I know all this is cause Im about 2 months further down the road.
Oh and ya are gonna need a tablet so you can have the app and be able to see the screen to make any changes to the settings.
Guess ya really gotta decide how much ya like your kid I guess.
