Navigating your way into the wilderness or any unfamiliar territory can be a challenging endeavor. Among the many methods you might employ, using a compass is a classic technique that has stood the test of time.

Despite its popularity, achieving pinpoint accuracy when navigating with a compass requires a deep understanding and a skillful hand. This article will help you fine-tune your compass skills, offering insights from an experienced outdoorsman.

Acquiring an Accurate Grid Bearing

Acquiring an accurate grid bearing forms the foundation of efficient navigation. Typically, one uses the edge of their compass baseplate to connect their current location to their destination, often known as rendezvous or R.V.’s. Accuracy is critical here, as any error will carry over when you adjust to a magnetic bearing.

To enhance your accuracy, consider using the parallel baseplate lines to connect your two points rather than the baseplate edge. This tactic addresses the issue of the thick transparent baseplates, whose bottom edges can be hard to see, thereby minimizing possible errors.

Grid Magnetic Angle (G.M.A.) Adjustment: Getting it Right

Once you have your grid bearing, the next step involves adjusting it to a magnetic bearing, factoring in the changes in the G.M.A. This adjustment needs to be as precise as possible, even with the limitations of bezel marking. Changes in the G.M.A. are calculated from your map yearly and vary by location, necessitating an accurate assessment of the time and area you’re in.

Fortunately, you can often find the required information for this calculation in the map legend. In the absence of a grid overlay on your map, your adjustment will be from true north to magnetic north, a process known as magnetic declination.

Maintaining Your Bearing: The Challenges

At this juncture, you’ve fine-tuned your compass and set your bearing. The challenge now is to maintain that bearing accurately as you travel. Unfortunately, a few factors can compromise your compass’s accuracy.

Avoid Accidental Bezel Movements

A simple accidental move of the bezel can result in a significant navigational error. Make a mental note of the bearing on the bezel every time you check your compass, ensuring it remains unchanged.

Mind the Parallax Error

Parallax error occurs when you look at the compass needle from a skewed perspective, causing it to seem within the rotating module markers when it’s not. Always view the compass directly above the center of the module to ensure an accurate reading.

Beware of Magnetic Deviation

Having items that exert magnetic influence near your compass can pull the compass needle off true north, causing a directional error known as magnetic deviation. It’s always a good practice to keep any magnetically influenced items away from your compass when navigating.

Follow the Direction of the Travel Arrow Correctly

When using a compass, following the direction of the travel arrow can be more challenging than it seems. Rather than staring at the compass while you walk, identify a distant object that aligns with the direction of the travel arrow and head towards it.

This method reduces the chances of veering off course. A sighting baseplate compass, such as the Silva type 54, can enhance accuracy in this respect.

Addressing Magnetic Inclination

Also known as the dip angle, magnetic inclination refers to the angle at which the magnetic flux enters the Earth. A compass needle is usually balanced for a particular region of the world.

If you use a compass outside its designated zone, the needle may dip and scrape against the bottom of the module, hampering its movement and leading to navigational errors. If you are a globetrotter, consider investing in a compass designed for all zones to avoid this issue.

Conclusion: Pursuing Navigational Excellence

Navigation is a complex yet captivating art, with each technique intertwining with others, presenting a complete, intricate picture. Consider these tips as stepping stones in your journey toward honing your navigational skills. With a bit of practice, your compass will become your trusted companion, guiding you accurately through your adventures.
