This slim-line chartplotter flush-mounts easily in your boat and sports preloaded detailed maps for the U.K. The GPSMAP 551 also features a 12.7 cm QVGA display and simple, straightforward buttons and menus. You can add the optional BlueChart® g2 Vision SD card for even more enhanced features.

The MAP 551 is supplied with internal GPS antenna, however an external antenna can be bought as an optional accessory (see accessories button).

Navigate with Ease

The 551 includes detailed coastal maps for the U.K. as well as a worldwide basemap of satellite images for other areas. The SD card slot makes it easy to add additional maps without connecting to a computer. And with just a few buttons and a simple, intuitive interface, the 550 makes navigating your way through the water easy.

Add Sonar

The sounder version, GPSMAP 551s, has the option of connecting a powerful dual frequency transducer that clearly paints depth contours, fish targets and structure when you're fishing. It's also CANet™ compatible, so you can share sounder data with another chartplotter on your boat.

Add Extras with BlueChart g2 Vision

With the optional BlueChart g2 Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.

• 3D mariner's eye view or fish eye view provides you with a 3-dimensional perspective of chart information, both above the waterline and below it.
• High-resolution satellite images and aerial photographs help you orient yourself in unfamiliar areas.
• Auto Guidance technology searches through all relevant charts to create a route you can actually follow — one that avoids obstacles, shallow water, buoys and other obstructions.
