The Garmin Edge 800 is a GPS-Enabled Cycling Computer which includes a heart rate monitor and Speed/Cadence Sensor. It sells for roughly $699 at Amazon but you can get it used for under $250 or refurbished for about $399. This is yet another GPS system built for a non-auto environment such as the Garmin GPSMAP 78
The Edge 800 display is 160 X 240 Pixels and comes with Garmin Connect Online Community which is used for analyzing, categorizing and sharing Data. It has a Virtual Partner and Virtual Racer with Auto Pause, along with a High-sensitivity receiver.
The Edge 800 has advanced heart rate-based calorie computations and barometric altimeter along with touchscreen and a very simple to use interface. It is 3.7 inches x 1 inches x 2 inches in size and weighs 3.52 ounces. A very compact design for your cycle.
It is billed as the first touchscreen GPS bike computer which can provide navigation and performance monitoring, which makes the Edge 800 ideal for touring, commuting, competitive cycling and mountain biking. It also has a built-in basemap which will track your distance, speed, location and ascent/descent.
You can use it with an ANT+ heart rate monitor, speed/cadence sensor or compatible power meter for a finely tuned analysis of your ride. This version of the Edge 800 is decorated in blue trim, and includes a premium heart rate monitor and a speed/cadence sensor, enabling you to gather more training data for analysis or sharing.
It also includes a microSD card preloaded with City Navigator for U.S., Canada and Puerto Rico street maps, which allows you to expand upon the basemap. The Edge 800 is also available on its own, with white trim.
The screen display is very sturdy to stand up to the elements, but will still respond nicely to the tap of your gloved hand. Switch training pages or pan and zoom the map with just a tap. The bright, sunlight-readable color display is easy to view in all lighting conditions. Of importance to all cyclers who will eventually run into the elements, the Edge 800 is waterproof to IPX7 standards and can withstand hard knocks and scrapes it might endure in mountain biking environments.
All in all an outstanding item to consider if you are a cycler who gets into other-world terrains.
