A compass is a navigation instrument with a free rotating needle that indicates the direction of the magnetic north. It is used for navigation in outdoor environments, especially in regions with weak or no magnetic fields, such as deep in the woods or in the mountains.

A compass is a must-have tool for anyone that is going to be out in the wilderness. It can be used for many things, such as finding your way, navigating the terrain, and much more. However, we recommend you use it for finding your way, as it is one of the most important things to do while out in the woods. 

The basic idea of using a compass is simple: you will need to turn the device in the direction you want to go, and then you will see the direction that it is pointing. You will see the number of degrees that you have to turn, and you will also see what the current direction is. If you are going to be hiking, you will need to know how much the slope of the terrain is, and this is where the compass comes in. With the compass, you will be able to see the slope of the terrain, and you will be able to measure it. 

We recommend that you use the compass for all of the above, and we also recommend that you download this app. It is free, and it will help you with all of the above.
