More details on the Garmin GPSMAP 66i
Overview: The Garmin GPSMAP 66i is a handheld GPS device and Satellite Communicator for use during many outdoor activities, such as boating, hunting, fishing, or hiking. It includes a 3" full color display with a resolution of 200 x 400 pixels. It is powered by a built-in Lithium-ion rechargeable battery with up to 35 hours of battery life in 10-minute tracking mode. The GPSMAP 66i has preloaded Garmin TOPO maps, with Direct-to-Device BirdsEye Satellite Imagery downloads. You can also add the optional inReach weather forecast service, if desired. The rugged GPSMAP 66i has an IPX7 waterproof rating, and weighs 8.5 ounces. It comes with a handy carabiner clip to secure it to your gear or clothing.
Global Satellite Receiver: The GPSMAP 66i includes support from multiple Global Navigation Satellite Systems (GNSS), including GPS and Galileo. You can toggle WAAS (Wide Area Augmentation System) / EGNOS (European Geostationary Navigation Overlay Service) on or off, if needed. In addition, the device has an electronic compass, barometer, and altimeter to help you as you navigate.
TOPO Maps/Satellite Imaging: The device is preloaded with Garmin TOPO maps for North and Central America that provide detailed views of terrain contours, topographic elevations, and summits, as well as parks, rivers, lakes, coastlines, and geographical points. You can also get BirdsEye Satellite Imagery directly downloaded to your device. This provides high resolution photo-realistic views of your route, trailheads, clearings, and more. The $29.99 subscription lasts for 1 year (from activation), and the imagery downloaded to your device during the year does not expire. You can renew after 1 year to receive further updates.
GPS Navigation and Tracking: After selecting a destination, the GPSMAP 66i can help you navigate to it. You can navigate using the map or the electronic compass. On the map, your route appears on the map as a magenta line, your location as a blue triangle. As you travel, the triangle moves and displays your path. Using the compass, an arrow points toward your destination, regardless of the direction you are moving. As you travel, the device records your path as an activity. The recording contains information about points along your path, including time, location, and elevation. Once you have reached your destination, you can navigate back to the beginning of your activity using TracBack.
inReach: The GPSMAP 66i has inReach technology to give you access to the Iridium satellite network for tracking and messaging, including sending an SOS. You can send and receive custom and preset text messages or emails, and receive a confirmation of its delivery. In case of an emergency, you can trigger an interactive SOS to the GEOS 24/7 search and rescue monitoring center. Pressing the dedicated SOS button sends a message to the International Emergency Rescue Coordination Center (IERCC), and they will notify the appropriate emergency responders of your situation. Of course, you should only use the SOS function in a real emergency.
inReach Weather: The optional inReach Weather Service provides detailed updates of the weather on your GPSMAP 66i device. You can request weather forecasts for your current location, or other waypoints or destinations where you'll be traveling. Cellular connectivity (through your mobile device and Garmin Connect app) is required for Active Weather, which includes up-to-date forecasts, and maps of predicted temperature, wind, precipitation, and cloud cover.
Mobile Connectivity: The GPSMAP 66i can connect via Bluetooth to your mobile device to provide additional connected features. Your smartphone will need the Garmin Connect app to pair to the device. Connected features include:
- Bluetooth Sensors: connect to heart rate monitors or other sensors
- EPO Downloads: Extended Prediction Orbit files help you quickly locate GPS satellites, reducing the time to obtain a GPS fix.
