Garmin GPSMAP H1i Plus
Description
Premium Navigation for Serious Adventures
The GPSMAP H1i Plus is designed for people who depend on accurate navigation in remote environments. Its large 3.5-inch color touchscreen provides a significant improvement in map readability while physical buttons ensure dependable operation when wearing gloves or during wet weather. The hybrid interface allows users to choose the control method that best suits the conditions.
Multi-band GNSS support improves positioning accuracy in difficult environments such as dense forests, deep valleys, and mountainous terrain. Combined with extensive preloaded mapping and optional Outdoor Maps+ content, the device provides detailed navigation for hiking, hunting, overlanding, mountaineering, off-road travel, and remote exploration.
Stay Connected Beyond Cellular Coverage
Built-in inReach Plus technology extends communication capabilities far beyond traditional satellite messaging. With an active subscription, users can exchange text messages, send photos, record and transmit voice messages, receive weather forecasts, and trigger an interactive SOS almost anywhere in the world using the Iridium satellite network.
In the event of an emergency, the dedicated SOS button connects directly with Garmin Response℠, Garmin's 24/7 emergency coordination center. Two-way communication allows users to exchange information with emergency responders while assistance is being coordinated, providing greater situational awareness throughout the rescue process.
Built for Extended Expeditions
The GPSMAP H1i Plus is engineered for extended trips where reliability and battery life are essential. Depending on operating mode, the rechargeable battery can provide up to 160 hours in standard GPS mode and up to 145 hours when using inReach Plus features, reducing the need for frequent charging during multi-day adventures.
The rugged housing is designed for demanding outdoor environments and includes integrated front and rear cameras, a built-in flashlight, expandable microSD storage, and USB-C connectivity for charging, data transfer, and software updates. Together, these features allow users to document their journey, navigate confidently, and remain connected while carrying a single handheld device.
Designed for Recreation and Professional Field Work
Whether navigating remote trails, conducting environmental surveys, supporting search and rescue operations, or leading guided expeditions, the GPSMAP H1i Plus combines advanced navigation with dependable satellite communications in one device. Its ability to share locations, exchange messages, capture photos, and access premium mapping makes it suitable for both recreational adventurers and professionals working where conventional communications are unavailable.
