Garmin GPSMAP 66i GPS and Satellite Communicator

The Garmin GPSMAP 66i is the ultimate expedition-grade GPS navigator and satellite communicator, combining best-in-class multi-satellite navigation with Iridium-powered two-way messaging and SOS capabilities in a rugged, purpose-built device. Its large 3-inch sunlight-readable color display shows topographic maps, satellite imagery, and navigation data with exceptional clarity even in bright outdoor conditions. The device acquires GPS, GLONASS, and Galileo satellite signals simultaneously for the most accurate and reliable positioning available. Two-way satellite messaging enables real-time communication with friends, family, and emergency services from anywhere on Earth via an active inReach subscription. Route planning, geocaching, and detailed topographic map viewing are all available on-device without a smartphone connection. The 35-hour battery life on standard GPS mode extends to weeks in expedition mode. MIL-STD-810 rated for shock, temperature extremes, and water immersion, it is the navigation tool of choice for mountaineers, expedition leaders, and serious backcountry navigators.
