Class Objectives Learn the Parts of the Lensatic Compass Learn the Proper Holds for the Lensatic Compass Learn your Cardinal Directions in Degrees Shoot an Azimuth Determine a Back Azimuth Use a Compass to Orientate your Map

The Parts of a Lensatic Compass Magnetic Needle Face Sighting Wire Rear Site/ Lens Thumb Loop Base Cover Graduated Scale Bezel Ring

Proper Lensatic Compass Holds Center Hold (less Accurate) Thumb Cheek Hold (Most Accurate)

Center Hold

Thumb Cheek Hold

Cardinal Directions In Degrees

Shooting An Azimuth Zero your Compass – Find Due North – Turn Bezel Ring Till Line is on Due North

Shooting an Azimuth Continued Find a permanent Stationary Object – Clouds – Animals – People Battle Buddy is Acceptable – Trees – Large Rocks – Light Poles – Radio Towers

Shooting a Azimuth Continued Use Thumb Cheek Hold Method Place Object on Sighting Wire Align Inside Rear Sight Look through Lens to Face of Compass Degree Will be Under Line You Now Have Your Azimuth

Determine your Back Azimuth You will First need to know your Azimuth If your azimuth is less than 180 you will need to add 180 More than 180 you will need to subtract 180 Example – Your azimuth is 45 degrees or 225 degrees 45+180=225 225-180=45

Use your Compass to Orientate your Map Find a flat non Metallic surface to lay your Map out. Find a North South Grid Line on Your Map Align the straight edge of your Compass on the North South Grid Line. Turn entire Map till Compass Faces North Adjust using your G-M Angle Chart Your Map is Now Orientated to Magnetic North
