Instead you will use an imaginary line that runs down the center of the compass. One advantage is it’s probably more accurate when it comes to “shooting azimuths,” meaning the act of determining the specific compass direction to a spot on the earth. Declinations to the west are subtracted from the degrees you are reading, lenstic declinations to the east are added.
The cover protects the compass from damage and also contains a wire stretched from top to bottom.
Definition of a Lensatic Compass So let’s get to the point, that being what the “lensatic” term means. Using a compass we can sight a bearing to our cabin across the lake. You lenastic use this feature to set your compass in the dark.

A lensatic compass, also called ocmpass military compass, is a more advanced and useful version of a magnetic compass. Generally once you have drawn your own Magnetic North line, you will not need to do this again on this map sheet for many years.
It’s so simple that most people can’t believe they didn’t realize it from the start. Whenever the luminous magnetic arrow lines up with the luminous short line, you’re following your intended azimuth. North is 0 degrees, so a declination of 10 degrees west would mean that you would point at degrees to point at true north.
The declination diagram may not be drawn with an accurate angle, or the angle may not represent the current declination. But not to you, I trust. While speed is important in many tactical situations, a lensatic compass is not necessarily designed for speed.
An “azimuth” is pretty much the same as a “bearing. Use a file to make a permanent notch at each end. Imagine that you want to hold it as if it were firmly mounted in that position. In the daytime, you’ll normally find something in the distance on your azimuth and walk to it, so you don’t have to keep staring at the compass.

An orienteering compass, for example, is designed for ease of use when taking a bearing from a map and heading off at full speed to the next point on a course. When performed correctly, you will return to the same line you were traveling before you encountered the obstacle.
Turn the compass cover more or less perpendicular to the base. Using our compass we have sighted a bearing to our cabin of mils from Magnetic North. Nowusing a straight edge, draw the bearing line and extend it in the desired direction. I keep one in my truck and one in my bug-out bag because they can save your life. lendatic
Going back full circle to the specific purposes that compasses are built for, we realize that a military compass would be used fairly frequently to take sightings. A truck, your radio, or even the barrel of your hunting air gun can push the needle away from north. The lensatic compass is used by the U. Or make a permanent scratch mark, paint line, or permanent marker line on each end.
With the thumb loop all the way down under the compass, put the thumb of one hand all the way inside the loop, and place the index finger of that same hand along one side of the compass.
