The
X6HR is the same size as the
X6. Both of these Wristops are similar in size to the
Observer which is about 30% smaller than all previous
Suunto Wristop models. The Metron basically is a heartrate version of the
Xlander. The
X6HR has a plastic body with a mineral glass crystal. The Metron has an Aluminum body with a mineral glass crystal. Beyond size, the main difference between the two models is that the
X6HR has a PC downloadable interface that gives you the power to graph your HR, Altitude, Ascent/Descent Rate and total vertical Ascent/Descent. This is a powerful
training tool for any outdoor event where monitoring your HR and altitude/ascent rates are important. Examples would be Running, Trail Running, Road/Mtn. Biking, Nordic Skiing, and Snowshoeing. Both the
X6HR and Metron have Altimeter/Barometer/
Compass/HR functions. I hope this helps.

 | 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. | |  |
