Types of Compasses

You may be a casual trekker or a professional on a huge ocean liner. No matter what your walk of life may be, a compass will always come to your help and assist you in reaching your destination. Here are the different types of compasses to choose from:

Baseplate Compass:

One of the commonest types and best compass for the money, the baseplate compass is liquid-filled and mounts onto a plastic rectangular base. A magnifying lens to read maps, luminous lamps for low-light reading form part of its components. This compass type is good for plotting but cannot sight distant objects as it lacks the necessary features.

Lensatic Compass:

Also called a military compass, the lensatic compass has three main parts:

  1. The base: This is the body of the compass which holds the needle, bezel or dial and rotating scales. 
  2. The cover: The sighting wire is housed here which protects the compass when shut.
  3. The rear lens: This projects outwards when you open the compass and serves to read the bezel or dial. 

Card Compass:

This type of compass is also called a marine compass as it is generally used on boats and ships. Unlike other compass types, it has a fixed needle that depends on a moving compass card for the correct directions. Since the moving absorbs the motion associated with boats, it is more dependable to have a fixed needle rather than a needle compass.

Thumb Compass:

Sports in which map reading and one's association with the terrain are important to use a thumb compass. Such sports are called orienteering sports. Here, the compass gets linked to the user's thumb and lets the competitor hold the compass and map in one hand while moving speedily ahead, whether on foot or by canoe or bike.

Prismatic Compass:

This compass is used by those who need extremely accurate navigation assistance. Sighting the prism lets the user read the compass while also spotting distant objects.

Gyro compass:

A gyro compass is a navigational compass that houses a gyroscope motor. This motor registers the direction of the true north along the earth’s surface. This compass does not rely on magnetism.

Electronic Compass:

This compass offers a numerical readout of one’s bearings. Not only does it give accurate readings but also allows you to store your bearings in the compass’ memory. The disadvantages are that this kind of compass is not ideal for map work, and it requires a power source to work, thereby rendering it unreliable.

How Does a Compass Work?

A compass works by finding out the Earth’s natural magnetic fields. The Earth’s magnetic field comprises two poles—north and south. These magnetic poles are a little away from the rotation of the Earth’s axis but are close enough so that the general directions along with some polar differences or declination can be used while navigating.

how dose compass work-pole magnetism


A compass is made of a lightweight magnet and a magnetized needle that is fixed to a free moving pivot. In this position, the needle reacts better to magnetic fields in the neighborhood. To locate north, the southern pole of the needle gets attracted to the magnetic north pole of the Earth.

How to Choose The Best Compass: Features to Consider

There are six main features to look out for when selecting the best compass:

Stability and Speed:

If a magnet's needle quickly points you in the right direction, that's better than a slow one as the latter can slow you down. This is particularly important if you're trapped in bad weather and want to find your way out of it quickly.


If you're using it when hiking, your compass must definitely be durable, or it might fall on the ground or get bumped while in your backpack. This is a common occurrence, particularly when you try to take your map out of your bag and the compass pops out. If it's windy at the time, the chances of your dropping it, only increase.

Declination Adjustment:

This feature is a must if you’re a hiker.

Sighting Mirror:

This feature has both adjustments of declination. So, if your need is for extremely precise navigation, ensure that your compass has a sighting mirror.


If you’re into backcountry skiing and mountaineering, your compass should contain a clinometer so that you can easily assess the hazards of an avalanche.

Global Needle:

Perhaps, you're a world traveler, or you're soon to be exploring a destination south of the equator. For either situation, you definitely need the best compass with a global needle.

Magnetized Needle:

At the heart of a compass lies its compass needle. Usually, the end of the needle that's red in color points towards the magnetic pole and this helps determine your direction with accuracy. Generally, the needle is made to float in a damping liquid for steady movement and accurate reading. However,, if it forms a bubble, the accuracy of the compass is impacted.

When and Why Should I Carry A Compass?

If you're traveling by road, hiking for days or are on the high seas, it's necessary to possess a compass and map. While traveling, you might just take a wrong turn. That's when the need for the best compass is truly felt.

Difference Between a Digital vs. Analog Compass

digital compass vs. analog compass

A digital compass is like its analog counterpart in the sense that both these compass types use the Earth’s magnetic field to determine the true North location, and both help trail makers, hikers, bikers and mapmakers in telling them which way they are going.

However, the difference lies in the fact that an analog compass can be wobbly due to some movement and can face interference from strong magnetic areas, thereby giving inaccurate readings.

On the other hand, a digital compass is sturdier and more accurate since it uses only the North Pole to guide it.

Tips on Using a Compass for Hiking & Backpacking

Here are a few tips you can use when going hiking with your compass:

  • Ensure that your arrow that shows your travel direction is actually pointing in the direction that you want to go.
  • Your orienting arrow should be pointing in the direction of the true north. 
  • Once you find your bearings, follow the travel direction arrow, not the magnetized needle.
  • When taking bearings, choose a stationary landmark.

Now that you know how to select the most accurate compass for your needs let me hop over and put before you the best available. This should lay to rest the question that perhaps dogs you every day, “What is the best compass to buy?”
