Garmin - Garmin eTrex Vista Handheld GPS Unit 

The eTrex Vista combines a basemap of North and South America, with a barometric altimeter and electronic compass. The compass provides bearing information while you are standing still and the altimeter determines your precise altitude. The Vista is also designed to provide precise GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS). This product will provide position accuracy to less than three meters when receiving WAAS corrections. A silver case gives this unit a high-tech look. New to the product design, Garmin will include marine aids to navigation in addition to the basemap. These navigational aids will be pre-loaded into each unit from the factory.
