I had always used Garmin, but 16 months ago I went with the new Hammerhead Karoo 2. Well that unit simply died. Hammerhead customer service sucks. So I did some research and decided on the new Garmin 840 that easily integrated with the new Shimano Di2 with no additional widgets. I hate the whole set-up process with new computers, but I dinged on a couple youtube videos and this thing was a breeze. It ain't cheap but it is an awesome computer.
I came from a Wahoo ELEMNT Bolt v1 which is great, but suffered from poor elevation readings. Have a Garmin watch and wanted to try the Garmin cycling computers. The 840 is must better computer: Easy to use and customize, better accuracy, and touch screen! Would recommend this to anyone.
More intuitive than previous versions. Faster than previous versions. Still has the issue where the altimeter/elevation calculator does work in the rain. Navigation still a bit wonky, especially on re-routing. Sporadic connectivity with my Garmin headlight, sometimes it connects, sometimes it doesnï¿½t. All in all an upgrade, but Garmin still has some bugs to work out.
