3-9 Barometric Displays (BARO SENSOR)
A barometric sensor in the microphone measures air pressure changes, enabling the radio to provide
three useful aids towards weather prediction and fishing conditions, particularly when you’re close to
large land masses. (See the information on the Happy Fish icon in Section 1-5.) The radio can show:
a weather icon to indicate five different conditions (SUNNY, PARTLY CLOUDY, CLOUDY, RAINY, •
SNOW). The local air pressure trends combined with the local temperature determines which
weather icon is displayed.
a digital readout of air pressure (in mb or in/Hg).•
