Dual Radar Support
BR24 and HD radar
Interference will be seen on BR24 at most ranges, when a pulse radar is transmitting
at the same time on the same boat. It is Navico’s recommendation to only transmit one
radar at a time: e.g. BR24 for typical navigational usage, or pulse radar to locate weather
cells, defi ned coastlines at a distance and to trigger Racons.
