I come from china and I'm a colledge student.
So I'm working on this question too. I have to choose one of them.
The
core has much new looks,more functions, like the sotorm alm ect.
But I have been told that, the
core's
compass works on a not vary professional way. I dont know the main idea.
Long before,I read some user's idea,he said that the sorftware using in the
core had some bugs,But before long,the commpany had solved the problems.
The must important thing is that,the
core is made in China,but the
X-Lander Military is in the local area.
If you want use it as a diving watch, I think the
X-Lander is the better one,because you can't press any key of the
core when you are diving, but the
X-Lander.
Last,I want to read more idea,thanks!

 | 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. | |  |
