The Garmin Forerunner 305 is the most accurate reliable wrist worn performance and GPS tracking tool you can get for the money. While no device this compact can quite do everything , the Forerunner 305 takes the boundaries of what is possible from something strapped around your wrist and extends them a lot further. The 305 includes wireless heartrate monitoring and it can also be connected to Garmin's wireless bicycle speed and cadence sensor
The 305's ability to both track, and maintain a lock on, your position is better than anything before it

While the Forerunner 305 isn't billed as a GPS navigation device, it does have some rudimentary mapping, waypoint marking, and route planning capabilities. In addition to marking locations along your journey, you can zoom in or out of a simple map that displays your current direction and path. There's also a "go to location" feature that routes you back to your starting location, or to any location you have defined.
The Forerunner 305 can display an impressinve array of data, including calories burned, distance, elevation, grade, and heading, as well as multiple lap and pace modes. The 305 adds the ability to track heartrate, lap heartrate, average heartrate, and heartrate zones via the included coded heartrate chest strap. With the purchase of a separate wireless cadence and speed meter, you can also track all important bike performance data.
Garmin have been designing their devices with USB connectivity for a while now which is a boon for those who struggled with serial port connections in the past. Thanks to USB the Foreruner 305 integrates seamlessly with the Training Center software and its easy to get your workout history uploaded and stored on the computer. Not only does Training Center, which is compatible with both PC and Mac,make it simple to track your performance, you can even make graphs using data such as heartrate, speed and distance. Over time, this analysis is a great way to view your fitness levels as it also helps you see what types of workouts are necessary to strengthen your weaknesses. For instance, if you see your heartrate spike at a particular distance, you know you'll benefit by increasing your endurance workouts to train that particular area of fitness.
