1. INTRODUCTION
Congratulations on your purchase of the GEO LITE, a geology-specific
version of the TruArc15 compass. This compass was designed with a new
clip-off lanyard and fixed drive ring and reversed bearings in order to make
it direct-reading and similar in function to one of our professional transits.
The needle has been fully redesigned to give accurate bearings and back
bearings and match well with our new azimuth ring. In order to facilitate
map work and angle measurement, the baseplate has been printed as a
protractor and the inclinometer spans a full 360 degrees. Additionally,
the cover is made of super strong 50% glass-fill nylon (that is 100%
recycled) and should protect your compass for years to come. Please fa-
miliarize yourself with the rest of this user manual to fully understand the
GEO LITE’s functionality.
