The azimuth
The azimuth is the most common military method to express direction.
What is the preferred method of using a lensatic compass when reading magnetic azimuths?
Given a compass and a designated point on the ground. Determine the correct magnetic azimuth to the designated point within 3 degrees using the compass-to-cheek method, or within 10 degrees using the center-hold method.
What is the azimuth in degrees to the steering mark?
At this position sight a back azimuth to the old steering mark. A back azimuth is 180 degrees away from a traveled azimuth. If traveled azimuth is less than 180 degrees, add 180 degrees. If traveled azimuth is more than 180 degrees, subtract 180 degrees.
Do I add or subtract the GM angle?
A typical note may read “To convert a magnetic azimuth to grid azimuth, subtract G-M angle.” If you have a magnetic azimuth of 270 degrees, and the G-M angle is 8 degrees, your grid azimuth will be 262 degrees.
How close will an 8 digit grid get you to your point?
10 meters
Remember, four-digit grids get you to within 1000 meters, six-digit grids to within 100 meters and an eight-digit grid gets us to within 10 meters.
What are the two methods of holding a lensatic compass and sighting?
The lensatic compass must always be held level and firm when sighting on an object and reading an azimuth. There are two methods of holding the lensatic compass and sighting. 16 Shoot an azimuth There are two methods of holding the lensatic compass and sighting. Compass-to-cheek method.
Is azimuth the same as direction?
An azimuth is the direction measured in degrees clockwise from north on an azimuth circle. The azimuth reading is 45° or the bearing is N 45° E. Notice that in this case the azimuth and bearing are both the same because the direction is in the NE or first quadrant. Azimuths can also be read from the south.
Which is the best technique for land navigation?
PART 1 Basic Land Navigation NOTE If you have MN LINES drawn on the map, align the protractor to a MN LINE, get the MN azimuth and you DON’T have to do MN conversions. TECHNIQUE # 1 (True North) 1. Identify several landmarks on the map and on the terrain. 2. Visually orient the map landmarks with the terrain landmarks.
What does the rear sight do on a camera?
c. Lens. The lens is used to read the dial, and it contains the rear-sight slot used in conjunction with the front for sighting on objects. The rear sight also serves as a lock and clamps the dial when closed for its protection. The rear sight must be opened more than 45° to allow the dial to float freely.
What’s the best way to use a lensatic compass?
The techniques employed when using the lensatic compass are as follows: a. Using the Centerhold Technique. First, open the compass to its fullest so that the cover forms a straightedge with the base. Move the lens (rear sight) to the rearmost position, allowing the dial to float freely.
How does the lensatic work for night navigation?
• With the Lensatic you just point and shoot one target and immediately move on to the next. • Luminous Lights allow for navigation in low-light conditions and night navigation. • Equipped with a magnifying lens, sight wire, and dial graduations in both degrees and mils to ensure accurate readings.
