Garmin has released a new version in the Edge cycling computer series. The new Edge 820 retains all of the core features of the Edge 810 with some notable enhancements. An all new housing and outer shell, similar in size to the Edge 520, brings the overall size of the unit down substantially, and different touch screen technology to improve user interface are amongst the most visually noticeable changes. However, these changes are just the tip of the iceberg. A host of other new features include: Group Tracking, Incident Emergency Detection, Wi-Fi Data Transfer, Battery Save Mode, Audio Prompts and 16GB of internal storage.
The Edge 810 is the most feature-laden cycling computer we tested, and is the winner of our Editors' Choice Award. With GPS, ANT+, Bluetooth, Maps, Shimano Di2 integration, and with some recent updates to the firmware, there is not much this cycling computer does not do. The large color touch screen makes it possible to scroll between page after page of data fields with a swipe of your finger. On a trip and don't know where to ride? No problem, create or download a pre-set course wirelessly using your smartphone and follow the turn-by-turn instructions. We initially thought that routable maps were a feature we would seldom use, but quickly found them to be indispensible for many types of riding. Despite the overwhelming number of features, the Garmin Edge 810 is intuitive and easy to use. If you cannot get enough data, then this is the computer for you. If you are technology-averse this is not the computer for you, try something more basic like the Cateye Strada Slim.
