Edge 305 comes packaged with a heart rate monitor, speed/cadence sensor, or both. These wireless sensors use ANT technology to send valuable workout data to the Edge.
Edge 305 + heart rate — measure your heart rate and track your heart rate zone with the lightweight, comfortable heart rate strap. Don't worry about cross-talk; ANT technology eliminates interference from other heart rate monitors.
Edge 305 + cadence — monitor your pedaling cadence and wheel speed as you ride with the self-calibrating, wireless speed/cadence sensor that attaches securely to your bike. You can even use it to train indoors because the sensor attaches to your rear wheel. As an added benefit, you can plan, analyze and store data from your workouts using free Garmin Training Center® software, which lets you analyze data with interactive graphs that chart your speed, time, heart rate and elevation.
