The
X9Mi is the best bet. First of all it has a
GPS which is fairly accurate I matched the coordinates with the web listed below. It features a
compass which can be set to match your declination. An altimeter and a barometer. The altimeter can be set to your location as well. With the rain storms here in Texas I was able to watch the barometric changes on my watch. Both of the last features will show recent changes in memory. I got mine last month and so far no problems. If you are still in the military you can get a
X9Mi through AAFES, which has no taxes. I was able to purchase mine for $369.00 they sell for a lot higher in the civilian markets. It is perfect for land navagation. So far I have not had any problemsI hope that 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. | |  |
