Map - ANS-Graphic representation of a portion of the earths surface drawn to scale.
Uses colors, symbols, and labels to represent features on the ground
Marginal information on a map - ANS-- Sheet name
- sheet number
- series name
- series number
- edition number
- map scale
- Adjoining sheets diagram
- elevation guide
- bar scales
- contour interval note
- declination diagram
- legend
Declination Diagram - ANS-indicates the angular relationships of true north, grid north,
and
magnetic north.
GM Angle - ANS-the difference in a grid azimuth and the magnetic azimuth for a certain
area. (use LARS rule)
GM Conversion - ANS-Applying angular difference between the grid north and magnetic
north to convert compass readings to grid version for use in navigation
Lensatic Compass components - ANS-Cover
Base
Lens
Compass Dial - ANS-part of the compass is delicately balanced and free floating when
in use. It can be locked in place by closing the eyepiece and also contains two complete
circular scales, one in degrees and one in mils.
Bezel Ring - ANS-part of the compass holds the upper glass crystal in place and
contains 120 clicks when rotated fully; each click equals 3 degrees.
Cover - ANS-Cover containing sighting wire
, Thumb Loop - ANS-This serves as a retaining device to secure the compass in the
closed position. It is also used as a wire loop for your thumb when you hold the
compass in position for sighting in on objects.
Black Index Line - ANS-Stationary line used as a reference line for determining direction
When the compass is held properly the azimuth found directly under the black index line
identifies the direction that the compass is pointing
Sighting Wire - ANS-The sighting wire and its use are similar to the front sight of a
weapon.
Base - ANS-Floating dial
Fixed black index line
Bezel ring
Thumb loop
Lens - ANS-Lens used to read the dial
Steps for orienting a map - ANS-Determine direction of magnetic north and the GM
angle on declination diagram
Align straight edge in the compass with a north south grid line
Rotate map and compass together signing the magnetic arrow and fixed black index
line
Rotate map until compass together until the compass arrow is aligned with the magnetic
north
Check compass reading
Center hold technique - ANS-Open the compass
Set the lens
Position your thumb
Position your fingers
Position your elbows
Advantages of center hold technique - ANS-It is fast and easy to use.
It can be used under all conditions of visibility.
It can be used when navigating over any type of terrain.
