Both models share
Suunto's ABCs (altimeter, barometer,
compass), but the
Core adds a number of new features including a storm alarm, sunrise/sunset times, etc.. If you don't desire the additional functions of the
Core, the decision will largely come down to which you prefer the looks of better.

 | Compass |  | Compasses are sensitive, absolutely crucial instruments to precision navigation. The earth's magnetic field, inclination, and your longitude and latitude all influence the horizontal plane of a compass needle. As a result, compasses are balanced for different geographical zones. Suunto Compasses overcome this limitation to traditional compasses by using a simple 'Two Zone System'. With a Suunto Compass, the only 'balancing zones' are the northern and southern hemispheres. In addition to this innovation, certain Suunto Compasses come equipped with useful features like luminous needles and marks, centimeter/inch scales, magnifying glasses, clinometers, sighting notches, and more. | |  |
