A compass is an incredibly useful, pocket-sized tool. It requires no batteries and can be used either with a map or on its own. However, these days it is typically only found in the kit bags of outdoors enthusiasts.
Knowing how to use a compass is ideal for those times when you’re
taking a trip and your phone runs out of battery, or when you’re travelling in
an area you don’t know well.
One important thing to know is that compasses are magnetic, which
means their arrow always points to magnetic north — this is different from true
north. Once you know how to follow its guidance, a compass can provide
consistent information regarding the land you’re on and the direction you’re
going.
Your phone does have a compass as one of its features, but you’ll
still need to know how to read it. Like reading a map, this list item falls
into the “good to have in your back pocket for emergencies” category.
