Quick Answer
To prepare for GPS battery failure in the field, carry a spare battery, learn to use a compass for navigation, and consider investing in a handheld GPS device with a long-lasting battery or solar charging capabilities.
Understanding Your GPS Device
Before heading into the field, familiarize yourself with your GPS device’s features and limitations. Check the device’s battery life and capacity, and consider investing in a spare battery or a battery pack. For example, some GPS devices have a spare battery slot or a battery life of up to several days on a single charge. Knowing how to replace a battery or jump-start a device can be a lifesaver in an emergency situation.
Using Alternative Navigation Methods
In addition to carrying a spare battery, learn to use a compass for navigation. A compass can provide a reliable method for determining direction and location, even when your GPS device is not functioning. Practice using a compass in different environments and conditions to build your skills and confidence. Consider investing in a compass with a declination adjustment feature, which allows you to account for local magnetic variations.
Preparing for Extended Use
If you plan to be in the field for an extended period, consider investing in a handheld GPS device with a long-lasting battery or solar charging capabilities. This can provide a reliable source of power and reduce the need for spare batteries. Look for devices with features such as low-power modes, solar charging, or battery-saving algorithms. Additionally, consider carrying a portable power source, such as a solar panel or a power bank, to keep your device charged and operational.
