The GPS 72 is a low-cost solution for land or marine navigation designed to provide precise GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS). The GPS 72 can provide position accuracy to less than 3 meters when receiving WAAS corrections. This rugged, waterproof, unsinkable GPS receiver offers a large, 4-level gray scale screen. It's designed as the next generation in basic, entry-level Garmin® GPS and is our suggested replacement for the GPS 12. Requires 2 AA batteries (not included). Meets The GLOBE Program® specifications.
