The Green Beret's Compass Course: The New Way to Stay Found (Not Lost Anywhere)

Never Get Lost: The Green Beret's Compass Course. Best and most simple land navigation system anywhere. We've sold over 45,000. The other two "methods" of finding your way around are:  Buy an expensive GPS and take lessons.  Learn to co-ordinate a map, declinate by adding or subtracting to compensate for the fact that Magnetic North and True North are miles apart.  More lessons. 
The Positive Azimuth, Uniform Layout system is simple.  No math (declination) required; no battery failure, no P-code dependence.  Kids learn easily.  System is now in use by elite military units.
