GoPro Accessories: These will vary for what you plan on doing with your GoPro, but to get the most out of your GoPro you will need a variety of mounts and there are a few things I recommend getting.
Cheap Accessory Kit – There are so many options for these, but for under £20 you can get a pack of most of the mounts/extra screws you will need. Most of these will be just as good as the official GoPro mounts – though at a much lower price (however there are a few things I would upgrade to something a bit more higher quality).
Suction Cup – Most that come in accessory kits don’t seem the highest quality. When you might be mounting this on the outside of a vehicle, I’d rather make sure I’m going with something reliable that won’t fall off.
GoPro Dome – This is a little bulky to travel with, but if you’re planning on being in water then I think this is a must have. Make sure to get one that fits your camera, and look out for one that shows the mid level line on the back (which can be helpful). And have as little as possible on the inside of the dome (as this will reflect and end up on your photos at certain angles). These will also often come with a float handle (which I never use with the dome – I just go handheld), but I usually like a different type anyway.
Float Mount – I’ve seen so many people lose their cameras in water because they didn’t have some sort of floating mount on them. My preferred one (other than the dome which will also float), is this small floating hand grip mount. It unscrews at the bottom to reveal a small compartment, which is ideal for storing keys and cash on beach/boat days where you don’t want to have to worry about a wallet.
Selfie Stick – Whether you like to use them or not, they can come in handy. Although stabilization is pretty good on the new GoPro’s, a high quality, sturdy selfie stick is worth investing in. There’s a huge variety, but I quite like this one which is inexpensive but sturdy and extends far enough without being too big.
