Amazon has currently discounted a couple of GoPro's newer action cameras, the HERO5 Session and the HERO5 Black. These are priced at $199 and $299 respectively. That's good for $100 off of each one, and good enough to bring these back down to their all-time lowest prices.
The GoPro HERO5 Session and Black are largely similar, however the Session is smaller, but it also does not feature a LCD display, so you can't see what you are filming from the camera, but you can using the GoPro app on your smartphone. The Hero5 series are both able to record in 4K, the Session has a 10-megapixel sensor while the HERO5 Black sports a slightly larger 12-megapixel sensor. Both can also take stills. These cameras are great to pick up if you are going on a hike, or are wanting to film something that you would rather not take a DSLR or a mirrorless camera to do. Like filming under water, as these are both waterproof, up to 10 meters.
