4. Position Eclipse 8099 at eye level and sight
through the sight hole.
5. Pivot your body until reflection of the blue
orienting circle outlines red circled "N".
(Figures 12 & 13)
· Do not rotate azimuth ring.
6. Sight destination or object through sight hole.
7. Travel to destination or object.
Always sight a destination or object in the distance.
Do not follow compass bearing by watching the
compass. If final destination is too far away to see,
sight a tree, mountain or something else and walk
to the object. At object, re-sight compass bearing to another object.
Repeat until final destination is reached.
6 – Topographic Map
A topographic map (topo-map) is a 2-dimensional drawing of 3-dimensional terrain. Hills, valleys,
ridges, cliffs and other terrain are represented through a series of contour lines. Each line
represents constant elevation in meters or feet above sea level. The contour interval (vertical
distance) between each line is indicated in the legend of the topographic map. Lines positioned
close together indicate a rapid change in elevation, while lines further apart indicate a more gradual
change in elevation.
With practice, you’ll begin to rec-
ognize many different contours
on a topo-map, and identify the
best possible route from one
position to another. (Fig 14) In
addition, by studying the map it
will be possible to identify
landmarks and determine
positions, bearings and
distances.
7 – Map Bearing
Whether in the field or at home, it is possible to determine a bearing from one position to another
directly from a map. The Eclipse 8099 provides two methods of finding map bearings – map
alignment and compass alignment.
7.1 Map Alignment
Align a topo-map to true north, then find a map bearing.
