The Core is the upgraded and updated version of the original Suunto Vector. Altimeter/Barometer/Compass/Log Book. All with new features.
The altimeter has a new start from zero function and intelligent switching between altimeter and barometer modes. This function is probably one of the most important improvements for the regular user. Added to the altimeter is a new depth measurement for snorkling and diving. Allowing depth measurement down to 10m.
The Barometer has a new easy to use storm alarm to warn of fast degrading weather.
The Compass has improved calibration and a warning message if the compass is not being held level.
Setting your location in the watch now allows sunrise and sunset calculations.
All of these features are combined into a slimmer watch body than the vector with a larger easy to read face.
All the watches have mineral glass screens for scratch resistance.
The vector was the wrist top that really launched Suunto into the outdoor market, and it has taken nearly 10 years for it be re worked. The Core looks set to carry on where the vector has left off.
