The advanced heart rate and training characteristics of the Polar CS600X make this the definitive cycling computer. In addition by using the compatible G3 GPS sensor (optional), you can track and record routes. The CS600X helps you optimise your training and determines if your training program and recovery time are developing your performance in the way that you want. This superb cycling computer also measures incline and regulates your efforts accordingly. Polar ProTrainer 5 software also views route information in mapping software, such as Google Earth Key Features of the Polar CS600X Cycling Computer Altimeter features * Altitude with graphical trend - available via PC software * Cumulative Ascent and Descent Barometer features * Temperature Basic features * Automatic/Manual target zone (% / bpm / HRR%) * Backlight * Display zoom * Easy start (setting wizard) * Graphical target zone indicator * Heart rate (displayed as % of maximum heart rate) * Heart rate (displayed as HRR%) * Heart rate (displayed as bpm) * Heart rate (displayed as graphical trend) * KeyLock * Over-sized display * User configurable displays * Visual and audible alarm in target zones * Water resistant - splash proof Computer connectivity * Compatible with Polar ProTrainer 5™ software * Transfer exercise data from wrist unit to polarpersonaltrainer.com via Polar WebLink (SonicLink/Infrared) Cycling features * Automatic display scroll * Autostart/stop * Bike mount * Bike settings - for three bicycles * Wireless Polar cadence sensor W.I.N.D. - opt. * Wireless Polar speed sensor™ W.I.N.D. * Calorie consumption rate/hour * Calorie consumption rate/km * Cycling Efficiency Index - opt. with Power Output * Cycling Limits * Distance * Distance based interval * Distance based recovery measurement * Estimated Time of Arrival * Graphical comparison of two values * Incline Measurement * Left/right balance - opt. with Power Output * Multifunctional handle bar/stem installation * Odometer (1/2 and total) * Pedaling index - opt. with Power Output * Polar Power Output Sensor™ W.I.N.D. - opt. * Speed (current, average and max) * Speed sensor installation for different fork shapes * SpeedPointer * Temperature and altitude * Trip Data transfer * Polar IrDA USB Adapter or internal/external non-Polar IrDA adapter GPS features * Battery type - opt. with G3 GPS sensor W.I.N.D. * Full power mode (up to 30 hours with an optional lithium battery) - opt. with G3 GPS sensor W.I.N.D. * Low battery indicator - opt. with G3 GPS sensor W.I.N.D. * Low power battery mode - opt. with G3 GPS sensor W.I.N.D. * Route tracking (with PC) - opt. with G3 GPS sensor W.I.N.D. * SIRF-III chipset - opt. with G3 GPS sensor W.I.N.D. * Shock resistant - opt. with G3 GPS sensor W.I.N.D. * Speed and Distance - opt. with G3 GPS sensor W.I.N.D. * WAAS support (wide area augmentation system) - opt. with G3 GPS sensor W.I.N.D. * Water resistant - opt. with G3 GPS sensor W.I.N.D.
