So let's explore how to adjust for declination and ensure you never stray from the path towards freedom!

Taking Azimuth Readings

Now that you understand the basics of using a lensatic compass, it's time to take azimuth readings.

Azimuth is simply the measurement of an angle in a horizontal plane between two points. In this case, we will be measuring the angle between our current location and our desired destination.

To take an azimuth reading, follow these steps:

  • Hold your compass level and steady.
  • Look through the sighting slot towards your intended target.
  • Rotate the bezel until the index line aligns with both north on your compass and your target.
  • Read the number where the bezel meets the baseplate.

Adjust for terrain by estimating how much higher or lower your target is than you are. This can affect distance measurements as well so keep that in mind. If you're at a higher elevation than your destination, subtract from your measured azimuth; if you're at a lower elevation, add to it.

Measuring distance accurately requires knowing what pace equals one meter or yard (depending on which unit you prefer) for you personally. Once you know this value, count each step as you move towards your destination and multiply by your pace length to get a rough estimate of distance traveled.

Remember that adjusting for terrain can also impact distance so be prepared to make adjustments as needed.

With practice and patience, taking accurate azimuth readings will become second nature to any aspiring navigator. Next up – using your compass in combination with a map!

Using Your Compass In Combination With A Map

Like a sailor navigating the open sea, using a map in conjunction with your compass can help you chart your course and avoid getting lost.
