Garmin GPSMAP 430s


Sweeeet! All in one package doesn't take up a lot of space yet the clarity of the screen, even in direct sunlight is great. Love the mapping and the sounder is heads above my old hummingbird. Would definetly recommend.

Product Specifications

This sleek, space-saving chartplotter is your companion for fresh water fishing and boating. The GPSMAP 430s features preloaded detailed maps for U.S. inland lakes as well as an ultra-bright 4" QVGA display, built-in satellite-enhanced worldwide basemap, and simplified user operation. The 430s comes preloaded with detailed maps for U.S. inland lakes, including 5300 lakes with shoreline, depth contours, and more. Over 300 of these lakes are enhanced with extra Inland Lakes Vision features. For areas outside the U.S., the 430s has a worldwide basemap with satellite images in place of more traditional maps, and its SD card slot makes it easy to add additional maps without connecting to a computer. With fewer keys and a simple, intuitive interface, the 430s makes navigating your way through the water easy. The 430s boasts advanced Inland Lakes Vision features for 300 of the most popular lakes. 3D mariner's eye view or fish eye view provides you with a 3-dimensional perspective of map information, both above the waterline and below it. Higher-resolution satellite images help you orient yourself in unfamiliar areas. Auto guidance technology searches through map data to suggest the best passage. The GPSMAP 430s comes with a dual beam transducer that clearly paints depth contours, fish targets and structure. It's also CANet compatible, so you can share sounder data with another chartplotter on your boat.
