Edge 705 w/ Heart Rate

Edge 705 comes with a built-in basemap, plus it has a microSD card slot for adding map detail and storing workouts, courses and saved rides. Just plug in detailed MapSource City Navigator street maps on a preloaded data card and get turn-by-turn directions on a sunlight-readable, color display as you pedal. Add optional topo mapping for your off-road adventures. Edge snaps easily into the included bike mount to guide you to your destination. Edge 705 automatically measures your speed, distance, time, calories burned, altitude, climb and descent, and records this data for your review. This version also measures heart rate and tracks heart rate in zones. For extra-precise climb and descent data, Edge also incorporates a barometric altimeter to pinpoint changes in elevation. It features a high-sensitivity receiver that holds a signal under trees and near tall buildings, and comes with a click stick for easy screen navigation. Can share data wirelessly with other 705 users. Edge 705 works with 3rd party ANT enabled power meters so you can see work output on the screen. Cadence functions can be added with the optional speed/cadence sensor (GN-CAD)
