Garmin Forerunner 305 Handheld GPS Receiver

Form meets function with Garmin's high-performance line of personal trainers - the Forerunner 305 & 205. The Forerunner 305 includes a high sensitivity GPS receiver, new courses feature and robust wireless heart rate monitor for optimal performance. Lock On to Satellite Signals Forerunner 305 sports a unique design that wraps the GPS antenna around part of the wrist for a better view of the sky, and its high sensitivity GPS receiver provides highly accurate speed and distance data, as well as improved tracking under trees and near tall buildings. Forerunner 305 also sports a robust ANT wireless heart rate monitor with softer, more comfortable chest strap and superior battery life. It eliminates cross-talk with other devices to reliably measure and send heart rate data, and it helps you train in your optimal heart rate zone. Take It to the Next Level Forerunner 305's courses feature lets you compete against previous workouts: you can compare your pace and heart rate to your past performance over the same run.
