The VIRB is an action camera that's similar to the Go Pro in a lot of ways. The weight of the unit is about the same and the HD quality of the video is pretty similar at 1080p. Though the unit is quite a bit larger than a Go Pro, you won't notice a difference with the bike mounts. The helmet and handlebar mounts worked well, but if we were going to choose one over the other, the helmet mount is the better choice.
The image stabilizer is good—probably one of the best you'll find of any action cam, including the Go Pro. It also has a separate button that's used for taking pictures, which keeps you from having to navigate back to the menu if you decide you want to take a picture on the fly. In photo mode, you can choose from a 16x9 format at 12 megapixels or a 4x3 at 16 megapixels. You can also switch to burst mode, which will snap five pictures over a 1- to 2-second time period. This makes it easier to capture the action if you're a novice photographer.
We liked the ability to pair the VIRB with other Garmin units, especially on the bike. The color viewer isn't the best and makes it difficult to see what you're actually filming. The menu navigation can be difficult to figure out too, but a lot of technical gadgets can be this way. Overall, as an action cam or a high quality camera, the VIRB is a solid unit that's tough and can take a beating. Look for a few updates in the future that could make this unit even better.
