Polar RS300X G1 Heart Rate Monitor Watch with G1 GPS Sensor

The Polar RS300X wrist heart rate monitor is designed to help you to train at the right intensity using core metrics such as heart rate, speed, distance, pace, and calorie burn. Advanced features include Polar's exclusive OwnZone--for individualized zone training by heart rate or pace, a fitness test, and auto lap splits, which display average heart rate, pace and distance per lap. Athletes can easily review up to 16 past workout files to check their progress and ensure they're staying on track with their fitness or training plan.

The addition of the G1 GPS sensor to this package enables you to combine heart rate with speed and distance to truly make sense of your training. The G1 sensor is ideal for athletes who mix up their training regimen with cycling, inline skating, paddling, mountain biking and/or hiking. The RX300X comes with the Polar WearLink+ 31 coded transmitter included with a changeable battery and is also compatible with Polar's S1 foot pod.

Key Training Features:

Heart Rate Readouts: displayed as percentage of maximum heart rate, BPM, and average heart rate of total exercise

Training Memory: Tracks your latest 16 training sessions and your last 16 weeks of training

Visual and audible alarm in target zones: Informs you every time your heart rate and/or speed/pace exceeds the upper limit or falls below the lower limit of your target zone during a training session.

Time in Target Zone: calculates the amount of total training time spent in your personal target zone. You can use this feature together with the Total Exercise Time to determine the effectiveness of your training program.

Polar OwnIndex Fitness Test: calculates aerobic fitness (comparable to maximal oxygen uptake, VO2max) providing a reference to base training intensity and measure improvement.

Polar OwnCal: Shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. 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.

Training Load: Helps you find the perfect balance between rest and training.

Event Countdown Timer: Keeps your motivation high by showing how many days are left before your next running event (e.g., Berlin 23 days).
