Units Tab
The Units tab enables you to define the units of measure.
The following settings are available:
• Depth —lets you select the units of measure for depth in
Feet (ft) , Fathoms (fa) , or Meters (m) .
• Temperature —lets you select the units of measure for
temperature in Fahrenheit (°F) or Celsius (°C) .
• Distance and Speed —lets you select the units of measure
for distance and speed readouts in Nautical (nm/ft, kt) ,
Nautical (nm/m, kt) , Statute (mi, mh) , or Metric (km, kh) .
• Position Format —changes the coordinate system in which
a position reading appears. The default format is latitude and
longitude in degrees, minutes, and thousandths of a minute
( hddd°mm.mmm’ ). The following additional formats are
available: latitude/longitude in decimal degrees (
hddd.
ddddd° ) and latitude/longitude in degrees, minutes, and
seconds ( hddd°mm’ss.s” ).

Heading
—sets the reference used in calculating heading
information for the Bearing, Compass, Course, and Track
Advanced Data fields (see page 37 ). True shows data
with reference to True North. Magnetic shows data with
reference to Magnetic North using the magnetic variation
value received in the RMC NMEA sentence (see page 16 ).
Time Tab
Use the Time tab to show the current time and date, adjust the 12
or 24-hour time format, enter a time zone, and adjust for daylight
saving time to show correct local time. The time appears only if
you are receiving valid NMEA input from a GPS unit (see page 16 )
or if the Fishfinder is in Simulator mode.
