The Garmin Oregon 550t provides high-end punch in an affordable package. This handheld unit features a 3" color touchscreen that gives you crisp clear viewing and is easily viewable in sunlight. The Oregon 550t comes standard with a basemap, preloaded U.S. Topographic maps including Alaska, Hawaii and Puerto Rico as well as the ability to load additional maps. The 850 MB of internal memory provides ample space for file downloads, while the MicroSD card adaptability is useful for those who require more memory for the pictures taken along the way with the internal 8 MegaPixel digital zoom camera. With 2000 waypoint capability, marking favorite spots just became much easier. The Oregon 550t is paperless Geocaching and custom map friendly, while the electronic compass features a 3-axis design, compensating for tilt and helping you see where you are going, even while standing still. The barometric altimeter helps this unit track your precise location, using changes in barometric pressure. This feature also allows you to keep an eye on ever-changing weather conditions by tracking barometric pressures over time. Wireless capability allows you to share waypoints, routes and geocaches with other compatible devices. Geocaching just got a lot easier as well, with the ability to download up to 4 million caches. You'll never have to worry about wet weather ruining your unit. With its weatherproof design, the Oregon 550t will stay dry and functional and is submersible up to 1 meter for 30 minutes. The Oregon 550t can be powered by lithium AA batteries (not included) or an optional lithium battery pack, both of which boast up to 16 hours of battery life. The Oregon 550t is also compatible with City Navigator software for auto-routing navigation. This handy little unit also features hunt/fish calendars, tide tables and sun/moon information, to give you the best data for your hikes, hunts and fishing trips.
