The GPSMAP 76 is designed to provide precise GPS positioning using correction
data obtained from the Wide Area Augmentation System. This unit features a
built-in quad helix antenna for superior reception and can provide position
accuracy to less than three meters when receiving
The GPSMAP 76 has an internal memory capacity of eight megabytes. In addition,
it comes with a built-in basemap of cities, coastlines, lakes, rivers,
interstates, and interstate exit information and a database of nautical navaids.
This unit has eight megabytes of internal user memory for storing optional
detailed maps, including marine cartography. This memory is preloaded from the
factory with worldwide cities (populations greater than 200,000) and nautical
navigation aids such as lights, buoys, sound signals and day beacons. The GPSMAP
76 is also preloaded with tide data for the United States.
An extra-large display measuring 1.6"W x 2.2"H gives users a clear view of
information, while a waterproof case means the GPSMAP 76 will keep working well
even if it's been submerged in water. Even more amazing, this unit will actually
float if accidentally dropped in the water.
