Garmin GPSMAP H1/H1i Plus
Garmin GPSMAP H1
The Garmin GPSMAP H1 is a rugged, navigation-only handheld designed for explorers who need reliability in the wild. It features a larger, high-resolution screen for clear map viewing, increased memory for storing maps and routes, and intuitive hybrid controls that combine touchscreen convenience with physical buttons for use in any condition.
Built with safety in mind, this device includes a bright LED flashlight and a powerful, loud siren that can be used to signal for help or alert your group in emergencies. Durable and dependable, the GPSMAP H1 is engineered to keep you on track and enhance your safety no matter how far you venture off the grid.
Garmin GPSMAP H1i Plus
The Garmin GPSMAP H1i Plus is a powerful handheld built for adventurers who want more than navigation alone. Along with a large, high-resolution display, expanded memory, and hybrid controls for ease of use in any environment, it introduces inReach Plus technology for off-grid communication.
Thanks to its integrated camera and microphone, you can send photos, voice memos, and text messages directly via satellite, ensuring you stay connected even in the most remote locations. Voice control lets you set waypoints or request weather updates hands-free, while off-grid satellite weather forecasts keep you prepared for changing conditions.
With a rugged design, built-in safety features, and up to 145 hours of battery life in GPS mode, the GPSMAP H1i Plus combines navigation, communication, and safety into one versatile device.
