Garmin GPS 152 4-Inch Waterproof Marine GPS

The GPS 152i features the latest navigational technology with compatibility for the Wide Area Augmentation System (WAAS). WAAS is an FAA-funded project to improve the overall accuracy and integrity of the GPS signal. It is a satellite-based system that broadcasts correction data as determined by ground reference stations. This system enhances accuracy of GPS positioning to about three meters, 95 percent of the time.

It is housed in a protective waterproof case and features a large 4-inch display. The high-contrast screen displays 100 x 160 pixels with adjustable backlighting for easy readability, while the well-positioned keypad on the bottom of the unit does not obstruct the display.

The GPS 152i receiver comes with internal GPS antenna, a gimbal mount, power/data cable, owner's manual, and quick reference guide. It is backed with a one-year warranty on parts and labor.
