Why We Like The GPS MAP 66i

The Garmin GPS MAP 66i is our ticket to staying connected to the world, even in the depths of the backcountry wilderness. Satellite communication enables two-way messaging and LiveTrack location sharing to keep our loved ones informed of our whereabouts, and with a subscription to inReach we can trigger an SOS to the GEOS 24/7 emergency response team in case of emergency.

Built for the long-haul, this rugged GPS handheld features a highly water-resistant design and a bright color display that's readable even in bright, sunny conditions, and the internal, rechargeable battery can provide a whopping 200 hours of life when set in expedition mode. It comes preloaded with Garmin TopoActive mapping for North and Central America, with multiple GNSS support and navigation sensors to guide your way. These detailed maps keep you informed of terrain contours, topographic elevations, summits, parks, coastlines, water features, and points of interest. And if you download satellite imagery off BirdsEye, you can get high-resolution photo-realistic views of your routes. Versatile and utilitarian, you can pair the GPS MAP 66i with your mobile device to help you plan your routes, you can check the weather with wireless cellular connectivity, but most of all—you'll navigate with confidence.
