GoPro may have popularized the action camera market, but there are plenty of competitors these days. YI came on the scene as a producer of affordable alternatives early on, but its latest release, the Discovery 4K, takes inexpensive action cams to a whole new level. The Discovery 4K has been discounted to just .99 with a coupon code applied at checkout.Of course, while the Discovery 4K is a good deal for the money, it's not as fully-featured as its upmarket stablemates. It can shoot 4K, but only at 20fps; it also shoots 1080p60, which is probably what you'll be sticking with. Its 8MP Sony IMX179 is the same sensor used on the Nexus 5, though it does have a 150-degree wide-angle lens. It has a 2.0" LCD touchscreen, which is pretty surprising to see at this price point. Eight shooting modes are present, and built-in 2.4GHz Wi-Fi allows it to connect to your phone within a 100ft range. It's not water-resistant, though IP68 water resistance can be added with a case that is sold separately.To get to that .99 price, you'll need to enter code FBYFC3CQ at checkout. Shipping is free, as it usually is on Amazon. If you've been in search of a cheap action camera, this is definitely worth consideration.Source: Amazon
