The Edge 305HR with heart rate monitor is the ultimate GPS-enabled fitness partner for cyclists. View larger. With a built-in barometric altimeter and heart rate monitor, the Edge 305HR goes a step beyond its little brother -- the Edge 205. The altimeter delivers extremely accurate elevation readings, while a chest strap monitor sends your heart rate data to the 305HR via a robust wireless transmission. In addition, the 305HR is compatible with the Garmin Speed/Cadence Sensor. This optional, self-calibrating wireless sensor attaches to your bike's rear chain stay and delivers speed and pace data while you train.

The Edge 305HR couldn't be easier to use. Simply take it out of the box, snap it into the included bike mount and hit the road. The high-sensitivity GPS receiver knows your position in tree cover and canyons, making the Edge 305HR an extremely reliable navigation device. And with the customizable cycle computer, you can select from up to eight different data fields for continuous feedback. Garmin goes well beyond typical cycle computers by integrating GPS technology for basic navigation. In addition, the Edge 305HR gives you the ability to overlay your ride data onto a course map and even "race" a virtual partner, making your training fun while helping to push you toward your goals.

The included, PC-based Training Center software gives you the tools to create workouts, manage and download courses, and create a detailed post-ride analysis that charts your performance and measures your speed, distance, climb, descent, and heart rate data against varying terrain, elevation, and more. And with the Edge 305HR 's built-in USB interface, it is quick and easy to upload and download information.

The virtual partner screen depicts a digital cyclist (representing your desired speed) in relation to your real-time speed. From this set of data the icons will show how far ahead or behind you are from your digital competitor. The "courses" feature allows you to race against a recorded course to try and match previously set speeds at every point along the way.

Training in urban areas can be tricky, and undesirable traffic can skew training data. To help remedy this problem, Garmin has included an auto-pause function that pauses the training timer when you slow down below a specified speed and resumes when you speed up again so you can focus on your ride, not on your data collection. And with the auto lap function, this smart little device automatically triggers a lap every time you pass a specified location or travel a preset distance.

With its sleek, waterproof design (the Edge 305HR meets IEC 60529 IPX7 standards, which means that its components can be submerged in one meter of water for 30 minutes), the 305HR is the perfect companion on any bike, and attaches to either the stem or handlebars. This lightweight device (88 grams) is powered by an 800mAh rechargeable lithium-ion battery and delivers an average of 12 hours of use per charge. The rugged case frames an easy-to-read, large, backlit display that makes it a breeze to view the data fields. So whether you're racing against your virtual partner, fighting to shave precious seconds off your old record, or training for the next big race, the Edge 305HR will help to monitor your progress and make you a better cyclist.
