The Garmin Oregon 450t is a mid-range, handheld GPS navigation device designed for outdoor use. Navigation of a worldwide, shaded-relief basemap is accomplished via a 3", sunlight-readable touchscreen. The 450t also features 3D topographic maps of the U.S. or Europe, with points of interest and more detailed terrain data. The Oregon 450t can wirelessly share waypoint and route data with other handheld Garmin GPS units. Geocaching support includes the ability to download GPX files, which hold location, terrain, and other details, to the device. A 3-axis electronic compass, without which a device must be held level to receive directions, and a barometric altimeter, which tracks altitude and predicts changing weather conditions, elevate the Oregon 450t above entry-level models. Maps can be added to the device via microSD card slot.
