Gauges and Almanac Information

Gauges provide various information about the trip, engine,
environment, and wind, and are available on all chartplotter
models. Numbers, Compass, and Trip gauges are available on
all chartplotters. Wind and Environment gauges require valid
wind data from the NMEA ® 0183 or NMEA 2000 network.
Engine gauges require a connection to the NMEA 2000
network, so they are not available on all chartplotter models.
The chartplotters also provide almanac information about tides,
currents, and the sun and moon, such as rise and set times.
