Are you looking to venture into the wilderness but fear getting lost in the vast expanse? You need to master the art of navigation using a compass and map. Though it may seem underappreciated in the age of GPS, navigating using a compass is still a valuable foundational skill that every hiker and backpacker should learn.
Why Should You Learn to Use a Compass?
GPS has been a game-changer in helping us determine our location in clear skies with great accuracy and speed. However, relying solely on GPS units could leave one stranded in the wilderness when they malfunction or run out of battery. That’s why it’s always advisable to carry a printed map in addition to a compass when venturing out in the great outdoors.
Having a map of the area you’re hiking in and knowing how to read it efficiently are invaluable skills that ensure you stay on track even in the worst weather or unforeseen conditions. Moreover, being adept at using a compass will help you orient yourself accurately and navigate with ease, even in unfamiliar territory, when the trail seems to peter out or is covered in snow.
Get to Know Your Compass
To successfully navigate using a compass, it’s crucial to understand its various parts, their purposes, and their functions. The compass comprises three primary parts: the needle, housing, and base.
The needle is a tiny magnetized pin that aligns itself with the earth’s magnetic field to point to magnetic north. The housing is a plastic or metal container that surrounds the needle, typically see-through and filled with liquid. The liquid dampens the motion of the needle, reducing oscillations and providing a more accurate reading.
The baseplate supports the needle and housing and contains a ruler and straight edges. These features are used for precise measurements when reading maps and plotting courses. The ruler measures distance on the map and translates it into real-world distances, while the straight edges help you plot a course along a set bearing.
By understanding the intricacies of the compass and its various parts, you’ll be well-equipped to navigate and explore the great outdoors with confidence and ease.
Correcting for Declination
Declination, the difference between true north and magnetic north, changes depending on a location. Accurately correcting declination, by adjusting the compass to the proper angle, is crucial before using it to navigate. Fortunately, most maps indicate the precise declination value to avoid navigation errors. Always remember, correcting declination not only helps you to navigate efficiently, but also reduces the risk of getting lost in the wilderness while exploring the great outdoors.
What are the Different Types of Compasses?
When it comes to navigational tools, there are different types of compasses to choose from – each suited to a specific purpose. For instance, if you’re a beginner, a baseplate compass would be the most appropriate choice as it’s the most common and simple to use. Conversely, for experienced navigators who require a more advanced sighting system, a lensatic compass has the perfect configuration. Lastly, if you need a compact model that’s easy to carry around and ideal for orienteering, a thumb compass is your go-to.
How to Find Your Location with a Compass
To determine your location on a map, there are several key steps that you must follow. First, you need to take a bearing and identify at least two visible landmarks in the distance. Once you have done that, you must use your compass and determine the angle between the two landmarks by sighting along the bearing to one of them and then rotating your compass until the other is sighted through a second bearing.
After you have determined this angle, you can compare it to the bearing on the map. If the angles match up perfectly, you can be assured that you are on the right track. However, if there is a difference between the angles, you need to adjust your course until the angles match and you are properly oriented on the map. This is a key skill for anyone who enjoys hiking, camping, or any other outdoor activity that requires good navigational skills.
How to Find Your Bearings With a Compass
To find your bearings using a compass, there are a few steps to take. First, ensure you’re holding the compass level, so the needle can move freely. Next, align the needle with the orienting arrow, which will also be pointing northwards. Once that’s done, turn the housing until the orienting lines align with the compass’s north-south lines. This is when you can read the bearing directly from the housing. Always make sure you’re in a stable position to get an accurate reading!
Common mistakes to avoid when reading a compass
Some common mistakes to avoid when reading a compass are:
- Reading the needle at the wrong end and setting off local attraction or declination in the wrong direction when the compass is being used
- Holding the compass too close to the body, which can cause interference with the magnetic field
- Calibration errors, which can cause errors in the eventual heading readings
- Deviation, which is the most common error in magnetic compass readings and occurs when the magnetic needle is affected by the magnetic field
Using Your Smartphone as a Compass
While a map and compass are the most dependable navigation tools for outdoor adventures, you can also use your smartphone as a trusty backup. Not only do most smartphones have a built-in compass, but also fantastic navigation apps that rely on GPS technology to accurately determine your location and help you plot your course. With the abundance of navigation apps available, you’re sure to find an option that works for you and fits your style of outdoor exploration.
Conclusion – how to use a compass
When heading out on a hiking or backpacking trip, it’s essential to have mastery of navigation using a compass and map. Although it may seem like a skill left behind in the age of GPS, a compass can save your life in case of electronics failure, which is common in remote areas.
Have you ever been lost in the wilderness with a dead cell phone battery? It can be an unnerving feeling, but with a compass and map, you’ll be able to maintain direction and return safely. It’s important to not only pack a map and compass but learn the basics of navigation before your trip.
Knowing how to read the topography and using a compass to determine your heading will give you the confidence you need to take on any terrain. So, if you want to level up your hiking game and be prepared for any situation, mastering the art of navigation will be a valuable addition to your skillset.
