Quick Answer
To maximize dual navigation, use GPS as the primary tool and traditional maps as a backup, cross-referencing both to ensure accuracy and avoid relying on a single method. This approach enhances reliability and reduces the risk of navigation errors. Practice using both GPS and maps to develop proficiency.
Choosing the Right GPS Device
When selecting a GPS device, consider factors such as battery life, water resistance, and user interface. Opt for a device with a long battery life (at least 20 hours) to minimize recharging intervals. Additionally, ensure the device is water-resistant and has a clear, intuitive interface that allows for easy navigation. Some popular GPS devices include Garmin eTrex and Magellan eXplorist.
Using Traditional Maps Effectively
Traditional maps provide a valuable backup in case the GPS device fails or loses signal. When using traditional maps, use a scale of 1:50,000 or 1:25,000 for detailed navigation. To enhance map reading skills, practice using various map symbols and learn to identify key features such as contour lines, stream networks, and road patterns. Consider investing in a compass, which can be used in conjunction with traditional maps to determine direction.
Cross-Referencing GPS and Maps
To ensure accuracy, cross-reference GPS data with traditional maps. This involves checking GPS coordinates against map locations to verify the accuracy of the GPS device. To do this, note the GPS coordinates (latitude and longitude) and match them to the corresponding location on the map. This simple step can help identify any discrepancies between the two navigation methods, allowing you to make informed decisions and stay on course.
