The Suunto Ambit2 Sapphire is best suited for beginners, professional athletes and mountaineers. It features different mode of activities and displays a variety of information and functions depending on the activity chosen.

For example, if you choose running, you will have to expect that the metrics displayed will be minutes/mile which is a standard metric for running, while on biking it will automatically display MPH (miles per hour). However, you can always configure which type of metric format you would like the watch to display.

There are other modes aside from running and cycling; there are outdoor swimming (open water), indoor swimming (swimming pool), trekking, triathlon, indoor training, mountaineering and other sports.  Each activity has its own options during calibration and has a pre-configured device pairings associated with it. There would be a heart rate strap or a bicycling cadence sensor. This device will ensure accuracy of information.

In each activity, your heart rate is measured accurately with the help of a heart rate monitoring strap. The accuracy of your heart rate is important as to determine your fitness level and your progress in each activity. The heart rate monitor chest strap, which comes with the device when purchased, can be paired with any ANT and so you can check information such as peak training effect, recovery time, real-time-heart rate graph and heart rate limits.

During the start of each activity, the device will look for a satellite in order to start with the GPS. It doesn’t really take too long for the device to catch the satellite and you’ll be -on your way. The GPS is accelerometer-integrated which allows you to track your speed and distance accurately. It also includes an automatic or manual setting of laps. This feature is useful especially if you are challenging yourself or training.

Aside from activities which require motion, the Suunto Ambit 2 Sapphire also has a navigation mode which allows you to create waypoints or points of interest using the device’s magnetic compass. Unlike the other compass which relies on speed to locate the heading, the Suunto Ambit2 Sapphire magnetic compass gives the correct bearing even upon rotation. So it’s really excellent in trekking or mountaineering.  You can also predict the weather with its barometric sensor and keeps you updated of the temperature with its thermometer.
