Using a Compass with GPS — Is It a Good Idea?

Understanding the Relationship Between Compass and GPS

While a compass is a more traditional navigation tool, GPS devices have become ubiquitous in the outdoor world. Using a compass with GPS can be beneficial in certain situations, but it’s crucial to note that GPS signals can be affected by vegetation, terrain, and magnetic interference, leading to inaccurate readings. In contrast, a compass relies on the Earth’s magnetic field and can provide reliable readings in most environments.

Combining Compass and GPS for More Accurate Navigation

To effectively use a compass with GPS, it’s essential to understand how to combine the two tools. This can be achieved by using the compass to determine a bearing and then using GPS to navigate in that direction. By doing so, you can cross-check the two tools and increase the accuracy of your navigation. For example, if you’re using a GPS device with a compass, you can set the GPS to show the bearing to your destination and then use the compass to navigate in that direction. This technique can be particularly useful when navigating in areas with dense vegetation or tall trees that can block GPS signals.

Minimizing Risks When Using a Compass with GPS

When using a compass and GPS together, it’s essential to be aware of the potential risks, such as over-reliance on technology and decreased situational awareness. To minimize these risks, it’s recommended to use both tools in combination, rather than relying solely on one or the other. Additionally, it’s essential to understand how to use a compass in the first place, including how to take a bearing, navigate using landmarks, and use celestial navigation. By developing a strong foundation in traditional navigation skills, you can effectively use a compass with GPS and stay safe in the wilderness.
