I'm on my second gopro silver. When you buy one, learn and use it a lot, and hope you can return it at store within 30 days with problems, if your gieger counter can't get through to gopro support. Most cashier jockeys aren't to up on what th (allot lots of time for that adventure.... sort of like calling the I R S.).You need to go to shopgopro.com/accessoriesfor for a big chunk of info and accessories. Gopro app and gopro studio are free.... the accessories are spendy and havn't found there to be any bargans. Don't use any memory card but 64 gb LEXAR. Cheapo mem. cards have something to do with "I ain't gonna work ,so I'm not gonna let you unlock me". So far everything is cool with no. 2. Great camera, but you do have to learn the system. Haven't tried under water yet since to use the screen you'll use the open door cover and I suppose all settings will have to be dialed in before dunking with the control buttons.

I'm old so getting SCHMARTER is a challenge.Good luck!
