The Discover GPS watch utilizes GPS technology to provide accurate speed and distance data, even over rugged terrain or when your stride varies. The included PC analysis software allows you to download and upload entire routes using Google Earth, and the software supports multi-user accounts on one computer. You can also use the Smart Lap Track/Log feature to map a route while you’re on it. For waypoint navigation, you can create up to 10 paths with 99 waypoints each. The Discover GPS allows you to capture, report, and analyze detailed training information. Watch functions or workout profiles can be set directly on the watch or on a PC and then uploaded to the watch. The watch’s digital compass features a 16-position directional indicator and displays bearing in degrees. In addition, the Discover GPS features an auto data log (120 log memory), a heart rate monitor (includes heart rate with three default target zones and one user-selectable), a 99 lap chronograph, a countdown timer, dual-time/day/date, and five daily alarms. The EL backlit full dot matrix LCD is easy to read and is protected by a scratch-resistant mineral glass lens. Water resistant to 100 ft. (30m).
