Hey,
Kids want an action camera for Christmas..
I have no idea about them but wish to spend around $200 so that rules out the latest GoPros.
I saw a new GoPro Hero 2018 for $200.. it is still worth getting at that price or should I get something else?
It also needs to be waterproof which I believe most action cams are?
try the ebay actioncam clone type cameras with waterproof body etc usually about 30, I have one 4k pics 1080 recording got a lot of attachments with mine have more than one kid buy two, there are many diff types at higher prices with better features but these are a guide
try here
