The GPS 152 is a 12 parallel channel GPS receiver loaded with a database of American cities and nautical navigation aids such as lights, buoys, sound signals, day beacons and tide data. Built-in memory of one megabyte makes the GPS 152 compatible with Garmin's MapSource® Points of Interest CD. With this CD and the GPS 152, you add additional marine navaid detail to your unit. (Other point of interest features from the POI CD-ROM will not be available for use with the GPS 152.)

In addition to larger memory, the GPS 152 is compatible with the Wide Area Augmentation System (WAAS), a technology designed to improve the accuracy of GPS positioning to about three meters.

On the outside, the GPS 152 comes housed in a waterproof case that’s about four inches high and five inches wide. A large four-inch diagonal, high-contrast display features 100x160 pixels for the ultimate in readability. A simple keypad at the bottom of the unit makes entering information easy, without blocking your view of the display.
