# How to Find Back Azimuth?

Back azimuths are calculated as follows: if the original azimuth is less than 180 degrees you add 180 degrees to the original azimuth, thus an azimuth of 45 degrees (<180) will have a back azimuth of 225 degrees. If the original azimuth is greater than 180 degrees you subtract 180 degrees from the original azimuth.

## How to Find Back Azimuth?

Finding back azimuth can be a difficult task, especially when you dont know where to start. Azimuth is a measurement of direction with respect to the cardinal points of a compass.

It is used to measure the angle between two points, usually two points on the earths surface. When you know the azimuth of two points you can use that information to find the direction in which you need to travel in order to get from one point to the other.

Finding back azimuth is simply the process of finding the azimuth of a point after you have already traveled in a particular direction.

The first step in finding back azimuth is to determine the azimuth of the two points you are trying to connect. This can be done using a compass or map.

With a compass, you will need to set the declination to the proper value, which can be determined from the map you are using.

Next, you will need to orient your compass to the direction of the two points you are trying to connect. You should be careful to make sure that the needle is pointing in the correct direction.

Once you have the compass oriented correctly, you can then use the azimuth scale on the compass to determine the
