1. Swimming Styles

There are different swimming styles. Your watch can track how you swim, and calculate different metrics for each swimming style. It can also track your total swimming time.

  • Freestyle
  • Backstroke
  • Breaststroke
  • Butterfly

2. Pace and Distance

The watch can detect your swimming style and use this information to give you accurate pace and distance measurements. Your pace and distance measurements are based on the number of turns you make, and how long the pool is. Every time you turn, the watch will measure one pool length.

3. Strokes

The number of strokes you take per minute is a good measure of your swimming efficiency. The watch will calculate this for you, and display it on the screen.


The SWOLF score is a measure of your swimming efficiency. It takes into account your pace, and the number of strokes you take per pool length. The lower your SWOLF score, the more efficient you are.

5. Pool Length (Used in Pool Swimming Profile Only)

You need to choose the right pool length for you. The length of the pool affects how fast you swim, how far you go, and your SWOLF score. You can choose the pool length in pre-training mode from the quick menu. The default lengths are 25 meters, 50 meters and 25 yards, but you can also set it manually to a custom length. The minimum length that can be chosen is 20 meters/yards.

6. Route (Only Used In Open Swimming Profile)

You can use the Flow app and web service to view your swim route on a map. Your route is recorded using GPS, but GPS does not work underwater. So your route is filtered from GPS data that is collected when your hand is out of the water or very close to the surface. External factors such as water conditions and satellite positions can affect the accuracy of the GPS data, and as a result data from the same route can vary from day to day.

Your heart rate and the heart rate

  • Your heart rate
  • Distance
  • Duration
  • Rest time (Pool swimming)
  • Pace (Open Water swimming)
  • Maximum heart rate
  • Time of day

A very handy feature to have, especially if there is particular metrics that are important to your fitness or performance goals.

8. Review You Session At The End

Once you have completed your swimming activities. You can review your training metrics at the end. All you need to do is go to the training summary feature on your watch and the watch will display information such as :

  • Date and time, Session length, Swim distance
  • Average heart rate, maximum heart rate, cardio load
  • Heart rate zones
  • Calories Fat burn % of calories
  • Average pace and Maximum pace
  • Stroke rate, average stroke rate, maximum stroke rate

You can use the Flow app to track your swimming sessions and see how you did. You can see your heart rate, pace, and stroke rate curves.

Is The Heart Rate Tracking Reliable During Your Swim Sessions?

It is fairly accurate, and to be fair tracking your heart rate during swimming is very difficult. With so much movement it is hard for the watch to pick up the information to track. However Polar have invested a lot of time into constructing a new sensor to eliminate this anomaly The Polar pacer uses the same type of heart rate tracking sensor as the Polar Vantage. Which is the Precision Prime sensor fusion technology.

Without getting to technical, sensor fusion relies on different information from multiple sensors to authenticate the correct information. Including the design of the sensors. It’s paced in a unique position to allow the sensors to collect data. The end result is a more accurate heart rate, that can be trusted when swimming.

Polar Pacer uses three sensors to obtain your heart rate

  • Heart rate monitor
  • Skin contact sensor
  • 3D accelerometer (movement sensor similar to a gyroscope)

All three sensors work together to track your heart rate during your swim session. Sensor fusion is very reliable, in fact I wrote a article earlier in the year about the Apple Watch 7. With the Latest operating system updates Watch OS9, sensor fusion was used to auto detect multi sport. It took away the manual application and allows the user to just focus on training, and the watch to track your training.

Polar Pacer Is Compatible With Wireless Sensors

If heart rate accuracy is a must for your training, then you may want to invest in 2 different wireless sensors that can be used to pair with the Polar Pacer via Bluetooth.

  • Polar H10 sensor
  • Polar Verity sensor.

Both very reliable heart rate sensors that are not attached to the wrist. Verity sense can be strapped higher on your arm, where as the H10 Polar sensor is a chest strap. If I was to choose between the 2, definitely go for the H10 Polar sensor. This device is the gold standard of heart rate tracking, and is the best device on the market.

Polar H10
H10 Polar Sensor : The Polar Pacer is compatible with this sensor. Regarded as the best heart rate tracker on the market. An excellent device to track accurate heart rate during swimming

Final Conclusion

The Polar Pacer is a fantastic fitness tracker for those who are looking to improve their swimming. It has a variety of features that make it stand out from other fitness trackers on the market, and its new sensor technology ensures that you get accurate heart rate data while swimming. If you’re serious about improving your swimming, the Polar Pacer is definitely worth considering.

Also if Heart rate accuracy is a must when it comes to your swimming training then you may want to look at getting the H10 Polar pacer heart rate monitor. Because the device is trapped to your chest, it wont be difficult to obtain accurate heart rate information in comparison to recording the info from your watch. Its a small price to pay, for such valuable and accurate information.
