Compass, Altimeter and Barometer

The Fenix 3 GPS watch has a compass that shows you where you are cardinaly. If you are traveling across different types of elevations, the altimeter will let you know where you are relative to sea level. This will monitor your ascent and descent while making it easier to follow a mountain map. It is also important to keep track of potential inclement weather while in the rough. The Feenix 3’s barometer will detects air pressure and calculate short-term trends so you can better predict the weather.


Most GPS watches use the US funded GPS group of satellites that orbit the Earth. With the signals from these satellites, GPS watches are able to detect the location of the watch anywhere in the world. GLONASS is another group of satellites that orbit the Earth. GLONASS was funded by the Soviet Union on a lower budget and has a lower satellite count. However, when used in conjunction with GPS satellites, location accuracy increases. This makes the Fenix 3 one of the best GPS watches on the market today.

Traceback your steps with TracBack

The TracBack feature on the Fenix 3 watch includes the ability to trace back your steps as you move through your trek. This feature will create a line through the zones which you have visited. You can also save particular locations in order to go back to them later. Since the Fenix 3 is Wi-Fi capable, you can share your saved locations and routes with your friends and family.

VO2 Max and Recovery Advisor

The Fenix 3 VO2 Max and Recovery Advisor, when used in conjunction with an external heart rate monitor, can determine your oxygen levels. By determining the amount of oxygen that you can consume per minute, the VO2 Max predicts your ideal finish time when racing. It can also predict your recovery time when doing vigorous activity.
