At the heart of your training is the coded T31. Its purpose is simple: to transmit your heart rate to your wrist unit. Slim and light, the ECG (electrocardiogram) accurate transmitter is fully water resistant and designed for all weather conditions. Built to last with up to 2500 hours of training usage. Prevents cross-talk from other electrical devices for accurate measurement of your training.
For ambitious cyclists, seeking improved cycling performance, the Polar CS500 presents the ultimate functional design for the ride. Take your training to the limits with daily personal heart rate target zones that optimise training, quick and safe control courtesy of the a rocker switch and oversized user-configurable display and complimented by altitude measurement that displays the inclines and declines of your ride. The Polar CS500 also guarantees interference-FREE transmission courtesy of W.I.N.D technology. Full features:Your cycling cadence stands for your pedaling rate in revolutions per minute (rpm). Cadence is the central factor in improving cycling performance. A higher cadence reduces the force needed for each pedal stroke, and thus improves overall performance. Running cadence measures how many times your either right or left foot hits the ground in one minute. Running cadence is measured as steps per minute. With this feature you can sharpen your cadence and make your ground contact time shorter. This will help you to find a balance between leg power and leg speed. Altitude is measured with an atmospheric air pressure sensor and shown as ascended and descended meters/feet and uphill/downhill steepness in percentages and grades.An automatic age-based target zone helps you train safely and effectively, determining your heart rate target zone limits automatically according to your age-based maximum heart rate (220 minus age). Heart rate is the measurement of the work your heart does. The CS500 allows you to set intensity targets in a number of ways and get a visual or audible alarm when you go outside of those present zones.
