A compass is, without a doubt, one of the most crucial pieces of equipment in any survival situation. The ability to navigate with a map and compass is an extremely important skill. Unfortunately, many people do not know how to use a compass and how to choose the best survival compass for their needs due to technology like GPS (technology allows people to forget past skills).
No doubt, GPS is handy, but if your battery dies or you do not get a satellite signal, it is nothing but a piece of junk. Due to this, it is wise to make sure that you have a solid compass in your hiking/camping backpack, survival kit, or bug out bag. In particular, a compass for hiking is a must.

HOW TO CHOOSE THE BEST SURVIVAL COMPASS FOR SURVIVAL
When you are checking out the best compasses for survival, there are a couple of features you should look for. These include:
Compact and Lightweight: It is always best to buy compact and lightweight survival gear, and this applies to compasses as well. You will want something that you can easily pack inside your backpack or carry in your pocket. This is one of the first features you should consider when choosing a survival compass.
Solid Construction: A survival compass with solid construction is a must. It should be able to withstand even the roughest conditions. Pick a well-built, durable compass so that even if you drop it, which you definitely will at some point, it does not get damaged. The best compass will have solid construction.
Water Resistant: There is no telling if you may have to swim across a river or it suddenly rains cats and dogs during an outdoor trip. Your compass should be water-resistant and waterproof so that you do not have to worry about damage even if you are soaked through.
Dry vs. Liquid Filled Compass: Nowadays, you will find dry and liquid compasses both have their own pros and cons. The type you choose depends on your needs and preference. If you pick a liquid compass, make sure that it has non-freezing fluid. The best compass will make sure the needle rotates freely.
Fixed vs. Adjustable Direction Arrow: You can choose a compass with either a fixed or adjustable direction arrow. Again, this depends on your personal preference and needs. Most outdoor enthusiasts choose a compass that has an adjustable arrow.
Rotating Bezel: Also known as an azimuth ring, a rotating bezel marked with 0 to 360 degrees encircles the needle capsule’s outer edge. When the interval of degrees is smaller, it is easier to navigate precisely which makes it easier for some to leave a city or a high tax state they no longer want to live in, among many other aspects that are important in life.
Good Base plate: A compass that has a decent base plate with measurements to calculate distances is critical. This transparent flat base has a number of navigational markings, such as a ruler that you can use to measure map distances.
Orienting Arrow and Meridian Lines: You should make sure that the compass you choose has orienting arrows and meridian lines. The markings on the base plate and inside the needle housing are helpful for a number of basic navigational tasks. Without these, orienting your compass to a map will be extremely difficult.
Declination Scale: A more sophisticated orienting arrow, this is a feature that every capable compass for hikers and other outdoor enthusiasts should have. This helps you in adjusting the readings of the compass to reflect the “magnetic declination” in your travel area, which is the difference between magnetic north and true north.
EXTRA FEATURES TO CONSIDER
• Clinometer: For backcountry skiing and mountaineering, a compass that features a clinometer is an excellent choice. It helps you in assessing the steepness of a slope as well as avalanche hazards as you climb.
• Sighting Mirror: If you want more precise navigation or to travel off-trail, you should choose a sighting compass with both declination adjustment and a sighting mirror. This helps you sight an object or direction simultaneously with the compass capsule visible.
• Global Needle: Whether you are a global traveler or going on a trip south of the Equator, you should get a compass that features a global needle. It compensates for variances in the magnetic field of the Earth and works accurately no matter which part of the world you are in. Yes, this compass can help you find the nearest Burger King or McDonald’s!
• Magnifying Glass: You will find some compasses that have a magnifying glass set into the base plate. These compasses are useful as you can use the magnifying lens to read small texts on a map.
• Luminescent Indicators: This feature allows you to read your compass at night. These indicators could be on the orienting arrow, magnetized needle, or the four cardinal points.
TOP 6 SURVIVAL COMPASSES
1. SUUNTO MC-2
The Suunto MC-2 has the added advantage of a sighting hole along with the mirrored lid. The sighting compass hole can be used at high elevations when you want to use a low-lying landmark as a reference point. The Suunto MC-2 along comes with everything you would expect from a modern well-made compass.
It also features a jewel bearing for stable and smooth needle movement, steel global needle, metric and Imperial distance measurements on baseplate protractor for charting an accurate map course, declination adjustment, and a 360-degree rotating azimuth ring with two-degree gradations.
Opinion: The compass comes with a complete set of measurement tools as well which makes land navigation very simple. All you need to do is hold the compass at eye-level with your target and the lid lifted so that you can see the dial of the compass in the mirror. You would need to rotate the bezel keeping the lid tilted so that you can see the dial of the compass in the mirror. Take note of your position and align it with the mirror’s sighting and you have your bearing.
A clinometer is featured in the MC-2 baseplate which makes slope incline and declines determination easy. We particularly like the sturdy built of the compass that is made in Finland and designed to last. Unfortunately, the mirror in the lid is a weak point and can break if not kept properly. However, the mirror is strong and is not very likely to break with normal use.

TYPES OF COMPASSES
There are various types of compasses. These are a few popular types of compasses:
Baseplate compass (Orienteering compass)
Baseplate compasses were invented in Sweden in the 1930s and helped in saving time while transferring bearings from the compass to a map. The compass is a great navigational device and a big help in direction-finding. The compasses are generally made from clear plastic and have a 360° dial mounted on a rectangular base. There is a magnetic needle in the raised dial that is suspended in a clear fluid.
A gyrocompass is an electric compass and is not affected by the earth’s magnetic fields. The readings in this compass are true bearings and don’t need any adjustment.
Needle compass (Pocket compass)
This compass has a magnetized needle. There are 360 equal units (degrees) in the fixed card. The compass is usually used by hikers. The needle freely aligns itself by moving in the magnetic north-south direction.
Prismatic compasses have a glass prism sighting arrangement. The compass also has a lid that allows objects to be lined up for sighting using a hairline. Within the base, you will notice the sighting compass card rotates and comes to rest at the required bearing. These are among the most sophisticated hand-held compasses.
Thumb compasses are a fairly recent modification of the baseplate compass. The baseplate in this model is remodeled to fit around the thumb of the holder. This allows the navigator to hold both the compass and the map in one hand, which leaves the other hand free for orienteering.
This compass type makes use of the path of the sun to indicate direction. This is a non-magnetic compass and works in reverse to the way a sundial works.
Astrocompass is similar to a sun compass in principle. It can be used in combination with any celestial body. Typically, the compass is used in aircraft navigation.
This is a composite compass instrument. It uses a gyroscope and a magnetic compass. The instrument quickly adjusts to various changes in course. This is why the compass has found widespread usage in aircraft navigation.
Frequently Asked Questions
What compass does the military use?
The US Military typically uses the lensatic compass, which is also known as a military lensatic compass. A military lensatic compass is made up of several different parts as opposed to a baseplate compass. These compasses are called ‘lensatic’ because they have a lens on the rear side. Military lensatic compasses help in the orienteering process.
How do I know if my compass is accurate?
To know whether your compass is accurate, you should observe the stability of the needle. Does the needle accurately point towards the magnetic north and settle quickly? You should make sure the needle doesn’t “stick” while it settles down for the last couple of degrees. Your compass should have a stable needle.
Why is my compass reading backward?
Your compass may read backwards because of reverse polarity. This is where the compass needle’s magnetism is permanently reversed. In this, the needle starts pointing towards the south instead of the earth’s north. This can occur if the compass is placed next to a weak magnet or a metal object.
Is a liquid-filled compass better?
Liquid filled compasses go a long way in reducing the dampening time. This is the time taken by the compass needle to settle fast, which can be a huge difference in a life or death situation. Needle placed in liquid moves freely and settles quickly.
What can ruin a compass?
Apart from regular physical damage, using your compass next to a weak magnet or a strong metal can ruin it. Depolarization occurs when you use your compass in a strong magnetic field. This may cause your compass to start pointing south instead of north. Using your compass next to mobile phones, GPS devices, home electronics or magnets among other things can ruin it.
Why do some compasses have MILS instead of degrees?
MILS is short for mili-radians. The term is derived from the fact that there are 2 Pi Radians in a circle. MILS is generally used by the military and is available in most tactical compasses. The original MILS system divides the compass face into 6283 divisions. This is useful in determining the range and scale.
What other advantages would a global compass have if I am not going outside North America?
Global compass has a unique global needle. These are quite beneficial even if you are not traveling outside of North America. The needle tilts up to 20 degrees, making it ideal for hikers that want to navigate without losing their stride. You can be sure of getting an accurate reading without having to level the compass.
As you can see, there are a few survival compasses that you can choose from in today’s market. The list has some of the best compasses you can find. These are reliable and accurate navigational tools that make a fantastic addition to any backpack or survival kit. In addition, you cannot do without a compass for hiking. Just pick the compass that has the features you need, keeping in mind your level of expertise and how long you plan to keep the compass before you upgrade to a better one. The trick to finding a wonderful compass is to focus on which is best for you.
