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.
