The GPSMAP 451 is a compact chartplotter that features an ultra-bright 4” QVGA colour display along with an improved high-speed digital design for increased map drawing and panning speeds. It’s ready to go with an easy-to-use interface and a built-in, satellite-enhanced basemap preloaded with marine charts for the UK and Ireland. The GPSMAP 451 also accepts BlueChart® g2 Vision cards for added features and functionality such as high-resolution satellite imagery, Mariner’s and Fish Eye views and Auto Guidance technology.
Explore the Seas
The GPSMAP 451 comes ready to go with preloaded marine charts for the UK and Ireland. For all other areas, the GPSMAP 451 has a worldwide basemap with satellite images in place of more traditional maps. The GPSMAP 451 also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. And with an SD card slot, it’s easy to add additional maps without connecting to a computer.
Add Sonar
The sounder version, GPSMAP 451s is compatible with an optional dual-frequency transducer for clear illustration of depth contours, fish targets and structure whether you’re fishing in freshwater or off the coast. The GPSMAP 451 and GPSMAP 451s are also NMEA 2000-compatible for easy connectivity with sensors, instruments and future marine offerings.
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 and Fish Eye view provides you with a 3-dimensional perspective of map information, both above and below the waterline
- 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
