1.4 Rotating Azimuth Ring (Figure 1)
The rotating azimuth ring includes a graduated dial (described in section 1.7). The
orienting circle and the graduated dial rotate with the rotating azimuth ring.
1.5 Index Lens (Figure 1)
The bubble shaped index lens magnifies the graduated dial (described in 1.7). Also, notice the
green index line in the center of the index lens. Read bearing and inclination at this line.
1.6 Rubber Shoe (Figure 1)
The removable rubber shoe encloses and protects the compass and a set of quick reference
cards (described in 1.11). Also, the rubber shoe can be used as a pencil eraser for maps.

1.7 Graduated Dial (Figure 2)
The graduated dial is graduated from 0° through 359°, in 1° increments. Read compass bear-
ing and inclination at the green index line in the index lens. Note the
for forward and back bearing, respectively.
1.8 Viewing Lens (Figure 2)
Use the viewing lens to magnify small writing on a map.

1.9 Orienting Circle –
blue Printed on the bottom of the vial, the adjustable blue orienting circle is used in bearing and
clinometer measurements as well as magnetic declination adjustments. Additionally, the
orienting line extending across the vial allows for precise bearing measurments and map align-
ment in some instances.
1.10 Clinometer Arrow –
Located inside the vial, the weighted
Eclipse 8099 is positioned on its side. Use the
the blue orienting circle, to measure angle of inclination.
1.11 Quick Reference Information Cards (Figure 3)
The quick reference cards supply quick, valuable information on navigation, formulas and scales
for in-field use.
1.12 Magnetic Declination Scale (Figure 3)
Magnetic declination is the difference between true north and magnetic north, at a position. The
magnetic declination scale, located on the bottom of the azimuth ring, is used in combination
with the adjustable
1.13 Clinometer Index Mark (Figure 3)
Use the clinometer index mark in combination with the
orienting circle to measure angles up or down from the horizon (0°).
