When it comes to GPS accuracy and reliability for runners, both Suunto and Polar watches have their strengths and weaknesses. However, it's important to note that Suunto watches generally have an edge in terms of GPS performance, particularly in areas with heavy tree cover or urban canyons.
Suunto watches use GPS, GLONASS, and Galileo satellite systems, which provide more accurate and reliable tracking than Polar watches that only use GPS. Additionally, Suunto watches have a feature called FusedTrack, which combines GPS and motion sensor data to improve tracking accuracy and minimize signal loss or interference.
Polar watches, on the other hand, have a feature called "GPS Band Technology" that is designed to improve GPS signal strength and accuracy. However, it doesn't perform as well as Suunto's FusedTrack technology in challenging environments.
When it comes to handling GPS signal loss or interference, Suunto watches have a feature called "Auto Backlight," which activates during signal loss to help runners stay on track. Polar watches, unfortunately, don't have a similar feature.
Finally, Suunto and Polar watches handle GPS data differently. Suunto watches use a feature called "GPS Smoothing" to filter out any inaccuracies and provide a more stable and consistent tracking experience. Polar watches, on the other hand, don't have a similar feature, which can result in more erratic tracking.
In conclusion, if you're a serious runner looking for accurate and reliable GPS tracking, Suunto watches are the way to go. Their use of multiple satellite systems, FusedTrack technology, Auto Backlight, and GPS Smoothing feature make them the superior choice for runners who train in challenging environments.
