Garmin GBR 23 new in the box

[Roy Randolph]

This is a Garmin GBR 23 ?DGPS? Antenna

DGPS was and still is used by many GPS units that can not use ?WAAS?

DGPS or differential beacon receivers use the old Loran system and transfers the signals to standard GPS format and allows you to get a much better accuracy with your GPS. This unit can be used with any GPS that accepts NMEA data. The unit is new in the box!

Garmin no longer produces these units since they started producing all their GPS?s with WAAS capabilities but are still sawt after by many people with older GPS units.

The unit sold for $180 to $250 I will let it go for $100
