Definition
A racon detects an incoming radar pulse and transmits a coded reply, which appears on the display as a dashed Morse character radiating outward along the bearing of the beacon, starting just beyond the beacon's true position. Racons respond mainly to X-band, so they will not appear on an S-band-only picture unless dual band. They mark landfall buoys, bridge spans and offshore structures, and the code is printed against the symbol on the chart.
