Garmin GPS 76 Portable GPS

The GPS 76 Portable Navigator is designed to provide precise GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS). This unit features a built-in quad helix antenna for superior reception and can provide position accuracy to less than three meters when receiving WAAS corrections. The GPS 76 Portable Navigator provides 1 megabyte of internal user memory to be used for storing downloaded points of interest data. This 1 megabyte of storage area is preloaded from the factory with worldwide cities and nautical navigation aids, and is perfect for downloading points of interest detail from Garmin's line of MapSource CD-ROMs. It is also preloaded with tide data for the United States. Even more amazing, this unit will actually float if accidentally dropped in the water.
