National Geographic Lensatic Compasses are reliable, rugged, hard wearing and build for survival. Issued to US troops because of the ruggedness and reliability. The lenstatic compass allows you to find an azimuth (bearing) calculate off for true North, align maps and much more. Comes with a pouch for handy carry in any survival situation. This is a must for all adventurers, preppers, everyday carry men, orienteers and adventurers. When camping, hiking, sailing, running from zombies or doing adventure races, a compass is a necessity. Learning the art of how to read a map is a skill we all need.

How to use a lenstatic compass.

Taking a Compass Bearing

Things You’ll Need:
  • Lensatic compass
  • Topographical map
  • knowledge of how to read a map

Step 1
Open the lensatic compass so that the cover is at a 90 degree angle and the lens bracket is at a 30 degree angle to the case. Check to make sure the dial is floating freely.
Step 2
Insert your thumb into the thumb loop.
Step 3
Hold the lensatic compass so it is resting on your thumb and bent index finger.
Step 4
Raise the compass to eye level.
Step 5
Line up a distant object with the sight wire and the center of the sighting groove in the lens bracket.
Step 6
Read the course bearing (azimuth) while keeping your head and compass still. There are two sets of numbers; degrees are in red and mils are in black.

Set a Course

Step 1
Open the lensatic compass completely.
Step 2
Place the compass on a level map with the azimuth directly under the index line. If you want to follow a 90 degree bearing, put the 90 degree mark under the index line.
Step 3
Hold the compass in this position and rotate the bezel until the luminous indicator is over the north “N” arrow. The course is now set. To check your course, open the compass and line up the luminous indicator with the “N” arrow. Do not move the bezel.

Following a Course

Step 1
Open the lensatic compass with the cover at a 90 degree angle and the lens bracket at a 30 degree angle to the case.
Step 2
Point the compass along the desired course bearing.
Step 3
Line up an easily identifiable object with the sighting groove and the sighting wire.
Step 4
Keep this object in sight as you travel.

Tips & Warnings
Practice using the lensatic compass using known courses in a non survival environment.
If you lose sight of your distant object when following a course, immediately stop and locate a new object to guide you.
If there are no objects to sight when following a course, find one to the side. When you reach the object, travel perpendicular to your course of travel to get back on course. Sight a new object and resume travel.
Never use a compass on or near metal or magnetic fields. This will affect the accuracy of your readings. Now you just need to learn how to read a map .
