Bushnell ONIX 350, Waterproof Hand Held GPS with 3.5" Color LCD & Digital Compass, Self Calibrating

The Bushnell ONIX 350 Waterproof Hand Held GPS combines navigational aids and georeferenced satellite photography on a single screen. It shows you the perfect pinchpoint for this wind. It's all housed in a rubberized defensive armor built to XPx7 waterproof standards, with a high gain SIRF GPS receiver in your palm.

Whereas all other dedicated GPS units rely on vector based graphics to display maps, trails and waypoints, the ONIX350 possesses the ability to rasterize a georeferenced satellite or aerial image on its large, vivid 3.5" screen. This results in a "real life" view of the area being navigated and is able to be layered over a vector-based map; switchable from one view to another with a push of a button. The ability to reference a true image of a route and its associated visual landmarks greatly simplifies and enhances navigation by GPS. Furthermore, the ONIX350 is bestowed with a range of features that allow users to use its advanced functionalities in demanding conditions.

Internally, there lies a 128MB microSD card to store waypoints, tracks and other navigational aids. As far as maneuvering is concerned, there is a built-in digital compass that is augmented by a barometer and altimeter to provide at-a-glance comprehensive geospatial and navigational data. For multi-day treks or where full-time GPS tracking may be required, the ONIX350 has a battery-saving mode called SafeTrack, which dims the LCD display without turning the radio receiver off. This way power drain is minimized and the length of operation is extended. Standard AA Alkaline, Lithium, or NiMH rechargeable batteries are compatible with the ONIX350 and are replaceable in the field at any time.
