Quick Answer
Use a GPS device with a reliable battery and keep it protected from extreme cold and moisture, and always carry a map, compass, and backup power source as a failsafe. Consider using a GPS with a long battery life, such as one with a lithium-ion battery that lasts up to 16 hours. Always navigate with a combination of GPS, map, and compass to avoid relying on a single tool.
Pre-Trip Preparation
Before venturing out, ensure your GPS device is updated with the latest maps and firmware. Check the device’s battery life and consider investing in a backup power source, such as spare batteries or a portable power bank. Additionally, pack a waterproof case to protect your GPS from snow, ice, and moisture.
Navigation Techniques
When using a GPS in winter conditions, it’s essential to use a combination of navigation tools. Set your GPS to a mode that filters out satellite signals from low-lying satellites, which can be affected by trees or mountains. Use the GPS to get a general bearing and then switch to a map and compass to confirm your route and identify potential hazards such as avalanches or icy terrain.
Device Settings and Safety
Consider setting your GPS to a “lock-on” mode, which will help maintain a satellite lock even in areas with tree cover or steep terrain. Also, make sure to set your GPS to a “locate” mode, which will help you quickly identify your location in case of an emergency. Consider investing in a personal locator beacon (PLB) or satellite phone as an additional safety measure in case of an emergency.
