Designed for the competitive cyclist, the Stealth 50 is GPS and ANT+ enabled, so it works with CatEye or third party ANT+ compatible power, heart rate, cadence and speed sensors.
ANT+ compatibility allows riders to track basic cycling data and combine with power, heart rate and cadence data to target and reach training goals. Upload ride data to help you visualize your activity, analyze performance and share your ride.
After going through two Garmin Edge units until they both failed, plus two Timex Ironman GPS units, I picked up this Cateye in June 2013. While the instructions are something lousy, once it is setup there are no problems. It will sync to both Strava and TrainingPeaks, which is a plus since I use them both. It also works well with my Garmin heart rate monitor and Garmin speed/cadence sensor.
