Garmin has an action cam you can shout at
Garmin was one of the first out of the gate, with a brand new action camera. Now they might not be as well known in this space as someone like GoPro but Garmin has been releasing well regarded cameras for a few years now, as a pretty natural extension of their fitness tracking products.
The Virb Ultra 30 brings in ultra HD 4K resolution video along with a touchscreen and proper 3 axis stabilisation, something that GoPro hasn't introduced, though we're pretty sure its about to.
