Garmin Forerunner 305

Garmin has produced some of the world's most popular GPS units since 1989, and has combined this GPS capability with the heart rate monitoring functionality of a personal training unit in its Forerunner line of products. The Forerunner 305 is the middle product in the Forerunner range, and is a step up from the Forerunner 205 in terms of functionality.

Like the Forerunner 205, the Garmin 305 Forerunner contains an internal GPS receiver, with a long antenna integrated into the wrist strap. This increases signal strength, lessening the likelihood of your signal dropping out while running or cycling under heavy tree cover. The internal GPS is also a wonderful convenience as opposed to make competing personal training systems, which require you to wear an external GPS separately.

The Forerunner 305's GPS can be used to enhance your workout in a number of ways. Using the included Garmin Training Center software, you can overlay your recorded training routes onto a satellite map, and study graphs showing your speed at different intervals and elevations. Additionally, the innovative Virtual Opponent feature allows you to race against a virtual you, using a previously recorded time on the same route. The Forerunner 305's display will show graphically how you are comparing to your previous run, giving you the opportunity to compete against yourself and continually strive for improvement.

The Forerunner 305 is also compatible with a number of accessories, such as the included wireless heart rate monitor strap, and an optional foot pad for runners and cadence sensor for cyclists. Using the foot pad, you can continue to track your speed and calories burned, even when your GPS signal drops out or when training indoors. The cadence sensor is also able to track speed and distance for cyclists when GPS signal drops out, and has the additional feature of being able to alert you if your pedaling speed ever goes too far above or below a value that you set.

Additionally, the Forerunner 305 is able to set heart rate alerts, a feature not found on the Forerunner 205. This allows you to maximize your cardiovascular workouts by setting target heart rates for the different portions of your workout. The Forerunner will then alert you when you are above or below these zones.

The unit includes a docking cradle/charging station, which allow you to easily charge it after each workout, and transfer the data that you have recorded to a computer for further analysis.

Garmin Forerunner 305 Summary:

• Personal trainer and GPS receiver in one unit
• Wrist strap contains extended GPS antenna, helping to prevent signal loss
• Compatible with additional accessories that the Forerunner 205 can not utilize, including a foot pad and cadence sensor
• Additional heart monitoring features
• Easily charging and data transfer via the included docking cradle
• Innovative Virtual Opponent feature allows you to race against your previous times
