Suunto Spartan Ultra
This extends battery life, but it means the GPS has less time to find a good fix and filter out
interference. So the resulting track is not as accurate as with Best.
With OK, the GPS fix rate is reduced to once every minute. This significantly increases battery
life, but results in a less accurate track.
Whenever you navigate a route or a POI, the GPS accuracy is automatically set to Best.
3.16. Heart rate sensor
Ⓡ
You can use a Bluetooth
Smart compatible heart rate sensor, such as the Suunto Smart
Sensor, with your Suunto Spartan Ultra to get accurate information about your exercise
intensity.
If you use the Suunto Smart Sensor, you also have the added advantage of heart rate
memory. The sensor memory function buffers data if the connection to your watch is
interrupted, for example, when swimming (no transmission under water).
It also means you can even leave your watch behind after starting a recording. For more
information, please refer to the Suunto Smart Sensor User Guide.
Without a heart rate sensor, your Suunto Spartan Ultra provides calorie consumption and
recovery time for running and cycling activities where speed is used to estimate intensity.
However, we recommend using a heart rate sensor to get accurate intensity readings.
Ⓡ
Refer to the user guide for Suunto Smart Sensor or other Bluetooth
Smart compatible heart
rate sensor for additional information.
See 3.24. Pairing PODs and sensors for instructions on how to pair an HR sensor with your
watch.
3.17. Intensity zones
Using intensity zones for exercising helps guide your fitness development. Each intensity
zone stresses your body in different ways, leading to different effects on your physical fitness.
