Polar RS300X

Average and maximum heart rates are monitored throughout each lap and RS300X will provide the average, minimum and maximum heart rate for the entire training session.

With the Polar RS300X, you can preset the heart rate range within which you wish to train. This helps you train at the right intensity for your goal and a visual and audible alarm will signal when you stray out of these zones.

Fitness Tests
Polar OwnCal: RS300X calculates your calorific expenditure during training. This feature lets you track the number of kilocalories burned in one training session, or a series of sessions over a period of time.
Polar Fitness Test: measures your aerobic fitness at resting just five minutes which will tell you what your VO2max is. This is the maximal oxygen uptake.

Polar RS300X features Polar OwnZone, which will determine your personal heart rate limits for a training session. Depending on the day and time, your physical state - which may vary if you  are tired, stressed, or not fully recovered from the last session, Polar can determine this state from your heart and will guide you towards the recommended training intensity.

Training Software
For analysis, you will have access to Polar's suite of online tools with Polarpersonaltrainer.com. This online portal lets you upload training data and set future sessions and goals using the Training Diary.
Training Load is a feature of the online portal, which lets you follow training load and recovery, to help you recognise personal limits and avoid any under or over training. You can then tweak your training sessions and goals according to daily and weekly targets.
Training programmes can be set up in Polarpersonaltrainer.com for running, cycling, outdoor sports and general fitness for example.

Add GPS
The RS300X is compatible with the Polar G1 GPS sensor. This comes as part of the package with the "RS300X GPS" version but can be purchased separately if necessary. The G1 GPS sensor will track your distance, speed, cumulative distance, average pace, current pace and maximum pace. You can use the G1 GPS sensor with RS300X to set targets based on speed and distance with an audible alarm sounding should you stray out of your intensity target.
