What are compasses?
What are compasses?
A compass is a navigation instrument which uses the Earth's magnetic field to tell us where magnetic north is. The magnetic needle in the compass points towards magnetic north, which allows us to determine what direction we need to travel in to reach our destination (known as a bearing).
In future lessons we will cover off how to use a map and compass to find bearings - STAY TUNED!
Can't I just use Google Maps to find my way?
Can't I just use Google Maps to find my way?
Google Maps is awesome to find your way from A to B and even tells you your current location - trouble is, it needs an internet connection. This means that if you're tramping somewhere without cellphone reception or electricity to charge your phone then Google Maps won't work! Compasses are small, light, and don't need electricity or an internet connection which make them ideal for navigation in the field
Types of Compasses
Types of Compasses
Compasses come in many different shapes and sizes - some are built for ships or aircraft, some come on keyrings, and some are built to be used by trampers. Remember though, they all do the same thing and allow easy navigation for all
Caring for Compasses
Caring for Compasses
Compasses are fragile tools and need to be cared for properly. If a compass is damaged it may not work properly, making it easier to get lost in the bush!
Keep compasses away from heat to avoid damaging the compass
Storing or using a compass near magnets or items with a magnetic field (such as cellphones, computers or radios) can demagnatise the compass, meaning it won't work properly!
Dropping or being rough with the compass can damage it and stop it from working properly
