Product Info for GARMIN GPSMAP 66sr Multi-Band Handheld GPS 010-02431-00

Between TopoActive maps of the U.S. and Canada and free BirdsEye satellite imagery, you'll see your position clearly on the Garmin GPSMAP 66sr Handheld Navigator's 3", sunlight-readable color screen. This feature-rich device employs five global navigation satellite systems-GPS, GLONASS, Galileo, QZSS, and IRNSS-for pinpoint positioning, even in heavy cover, mountainous terrain, or urban canyons. The built-in barometric altimeter and three-axis compass add more information you'll need in your travels. The navigator comes pre-loaded with Garmin's TopoActive maps of the US and Canada. Updates come automatically from Geocaching Live, including descriptions, logs, and hints, and upload to your profile.

The LED flashlight is sure to come in handy when you stop for the night, and its built-in rechargeable battery will let you stay out for many nights-runtime for the GPSMAP 66sr is 36 hours in standard mode and 450 hours in Expedition mode (the screen is off but you're still dropping track points.) Pair the navigator with your compatible smartphone or device and you'll get the latest updates from Active Weather. You can use the device to plan, review, and sync your travels via the Garmin Explore app and website. Built for the rigors of the outdoor life, the GPSMAP 66sr is IPX7-rated waterproof and meets MIL-STD-810 standards for thermal, shock, and water resistance. It measures 6.5 x 2.4 x 1.4" and weighs 8.1 ounces.
