On paper, the Ultra 30 offers just about everything you could ask for in a modern action camera: GPS, 3-axis optical stabilisation, livestreaming abilities, editing software, and a waterproof case. You'll also find an accelerometer, gyroscope and barometer built in.
The cam is capable of grabbing 4K UHD video at 30fps, but can shoot slow-mo at 720p/240fps if you'd prefer. The image stabilisation will suck more battery from the Ultra 3, but you'll get silky smooth footage as a result - although likely within reason.
Additionally, the cam can take 12MP still photos if you're not taking it out to break a sweat.
Garmin's even chucked in some voice controls: you'll be able to say "Ok Garmin, start recording" or "Ok Garmin, remember that" - and it should obey your commands.

Then comes the livestreaming. Garmin says you'll be able to stream to YouTube, but if you want it on Facebook you'll still have to upload it after the fact.
In addition, the app will let you control the Ultra 3 with your smartphone, via Wi-Fi - or data if you're livestreaming.
As for the waterproof case we mentioned, Garmin says you'll be able to use the touchscreen regardless of whether the camera is inside said case or not.
Finally, Garmin's VIRB Edit desktop software lets you auto-create videos using auto-picked highlights - similar to what we've rivals like TomTom do with their action camera software.
All that said, it's not cheap. The Ultra 30 is available now with an RRP of ¬£449.99.
