When it comes to navigation during overlanding, GPS systems offer several benefits over using a phone. GPS devices are designed for outdoor use and can withstand harsh conditions, such as extreme temperatures, dust, and water, better than phones. They also offer more accurate and reliable navigation, with preloaded maps and satellite connectivity even in areas with no cell service. GPS devices also have longer battery life and are more durable than phones. They can also be used as a standalone device, freeing up your phone for other tasks. Additionally, some GPS devices come with additional features such as tracking, geocaching, and route planning that can enhance your overlanding experience.
