Altimeter 
The altimeter features a range up to 9,000 m / 29,500 ft, putting all 14 of the world's 8,000+ meter summits within your reach. Suunto Vector also features an altitude difference measurement function for following the vertical progress between different stages of a climb. It has an automatic 24-hour memory that stores the altitude and ascent/descent rate for every hour and also features an adjustable altitude alarm and a number of different memory functions. With the unique logbook function, you can also record your total and cumulative vertical ascents and descents, as well as the number of runs skied. 
Barometer 
Suunto Vector displays the current barometric pressure and temperature, enabling you to forecast weather changes when they matter most. It also automatically records barometric data for the past four days: the first six hours in one-hour intervals and in six-hour intervals thereafter. When the reference altitude is set correctly, the instrument also shows the present sea level pressure, making it easier for you to read and understand the barometric pressure at high altitudes. However, when touring the mountains, don't forget that the detected barometric pressure changes when you are moving in a vertical direction, which at times, makes the tracking of weather changes a bit more complicated. 
Compass 
The digital compass of Suunto Vector guides you with cardinal or half-cardinal points and the north-south arrow. The compass can also be set to track a certain bearing, which helps you follow a desired direction in unknown terrain. The declination adjustment function allows you to correct the difference between true north and magnetic north, for a more accurate reading and direction. 
Time 
In addition to the outdoor-related functions, Suunto Vector also displays current time, in either 12 or 24-hour format. It has three daily alarms, a calendar programmed to the year 2089, a stopwatch with split-time measurement, and a countdown timer.
