The Garmin GPSMAP 451/451s Chartplotter series units are simple to use and reliable and they are supplied pre-loaded with UK and Ireland mapping, which is perfect for those who want easy-to-use navigation data.

Sailors will appreciate how they can get this unit working straight out of the box with its built-in GPS antenna, its bright 4-inch QVGA display and the reassurance that the Garmin GPSMAP 451 and 451s Chartplotters are both waterproof to IPX7 standard and both are also NMEA 200 compliant and also support the AIS (automatic identification system) and DSC (digital selective calling) systems.

Garmin GPSMAP 451 and 451s models differ in that the 451s is fitted with a built-in sounder.
