First you read the compass. Then you find the correction for the heading closest to the heading the compass reads, interpolating if needed. Then you add the correction to the heading to get the corrected heading.
For example, say the compass read 37 degrees and the correction card had a +2 correction for 30 degrees and a -1 correction for 60 degrees. You would interpolate a correction at 37 degrees of about +1, and add that to 37 to get a corrected magnetic heading of 38 degrees.

Lensatic Compass is a kind of compass which uses a magnetized dial, a lensatic compass features a special card which helps the users in reading the directions easily. A Lensatic Compass is very useful device because it has numbers which are useful in identifying the directions of target objects. The use of Lensatic Compass involves difficulties in using it.It is important to learn how to use a lensatic compass properly prior to using it, also other materials like a map and a protractor are also needed when using the compass.

Compasses are used in a variety of modern applications, including navigation for hikers, backpackers, and wilderness enthusiasts, as well as in orienteering sports. They are also used in military and search and rescue operations, and as a backup navigation tool in case of technology failures. Additionally, compass apps are available on smartphones for everyday use.

To use a prismatic compass, first ensure it is set up correctly by adjusting the azimuth ring to align with magnetic north. Then, hold the compass level and sight your target through the prism while reading the azimuth on the compass dial. Ensure you compensate for any declination angle if needed.
