Major Fetures of the CS300
- Wireless Polar CS speed sensor
New advanced Wireless sensor that provides current, average, and maximum speeds. Easy attachment and aerodynamic design.
- Cycling Economy
Cycling workload as kcal/h and kcal/km. With this feature you can foresee your calorie expenditure and secure sufficient intake on a long ride. Also useful for comparing and analyzing the loads of various training types. It also measures how economical your training is.
- Estimated Time of Arrival (ETA)
Enables you to foresee the time of arrival based on your cycling speed. Set the distance you are going to ride, and your cycling computer calculates the estimated time of arrival based on your cycling speed.
- Speed Pointer
Indicates the relation between current speed and average speed.
- Zone Pointer
Makes it easy to stay in your target zone.
- Polar OwnCal®
The Polar OwnCal feature shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions.
You can set daily and weekly exercise goals in terms of calorie expenditure with the OwnCal feature. Because the OwnCal tracks both the energy expenditure during one exercise session and the accumulated kilocalories during a longer time e.g. one week, it helps in achieving both short term and long term goals.
- Polar OwnCode® (5kHz)
Prevents cross-talk from other heart rate monitors.
- Polar OwnZone®
The Polar OwnZone (OZ) feature determines an individual exercise zone. It guides you through an appropriate warm-up routine and automatically determines a safe and effective exercise heart rate zone - your OwnZone - while taking into account your current physical condition.
