Discover the precision of Differential GPS with the new GARMIN GBR 21.

The GBR 21 receives Selective Availability and atmospheric corrections for GARMIN GPS units so you can take full advantage of 5-10 meter GPS accuracy. Whether you are navigating through a crowded channel, finding your way to an important fishing spot or pinpointing a specific dive location, the GBR 21 can help you hit the spot time and again. Designed for convinient remote mounting, the GBR 21 is controlled right from your Differential Ready GPS receiver with simple key commands. Differential GPS corrections are broadcast by United States Coast Guard and IALA (International Association of Lighthouse Authorities) beacons free of charge to mariners. These signals provide information on satellite status and health in addition to the location, frequency and status of the beacon transmitter. The GBR 21 quickly decodes this information for use by your GARMIN GPS receiver, correcting for Selective Availability and atmospheric errors.

The GARMIN GBR 21 gives you access to the most accurate form of GPS navigation, with potential for 5 meter precision. This accuracy is available now from active beacons on most of the eastern seaboard and parts of the Texas gulf coast and the Great Lakes. The U.S. Coast Guard's current plans call for complete coastal coverage in the U.S. by the mid-1990s.

The GARMIN GBR 21 even includes a handy reference card listing both active and planned beacons, noting their position and frequency.
