7.2 Compass Alignment
Compass alignment
method allows for bearing
determination without
aligning the map to true
north. Use this method for
pre-planning at home or in
the office.
1. Adjust for magnetic declination (indicated on map).
2. Draw
true
north-south lines. Space approximately 1 inch apart. (Fig 15)
3. Mark start position with a “point”, destination with an “X” and connect with a line.
4. Place compass next to the bearing line.
5. Rotate
azimuth ring
until
blue
orienting circle
points in a northerly direction, and the
red
lines on
graduated circle are aligned with the drawn true
north-south lines. (Fig 16)
6. Read bearing.
Note:
If magnetic declination is 0
o
, or declination is
unknown, adjust compass to 0
o
declination,
and align both the
blue
line, in the vial, and
the
red
lines on the graduated circle with
the map’s true north-south lines.
8 -- Distance Measurement
Now that you have established a bearing, find
distance using the ruler. If needed, slide the ruler
completely off the Eclipse 8096, flip over, and slide
ruler back on the compass. (Fig 17)
1. Measure distance from the “point” to the “X” on
the map - 6 inches. (Fig 18)
2. Find actual distance, by comparing measured
distance to the scale in the legend of the map.
