•Background Color (Fishfinder 250C only) — allows you to change the background color of the sonar display. Choices are Black, Blue or White.

•Number Size — allows you to choose between a Normal or Large sized Basic depth/temp/speed display. This does not change the Advanced data field number sizes.

•Temperature and Water Speed — hides or displays temperature and water speed on the Sonar Page. When set to ‘Auto’, the unit automatically displays this information only if it is received from the transducer.

Tools Tab

Controls the display of useful sonar tools. The following settings are available:

•Flasher — this option activates a graphic Flasher representation, displayed on the right side of the graph. The graphic Flasher displays structure and bottom returns much the same as a true Flasher. You may find this feature particularly useful when using ‘Fish Symbols’ (see pages 11 and 16).

•Color Bar — shows a gradient scale of the current Target Level setting (see page 13).

•Temperature Graph — toggles On or Off the display of a temperature graph on the Sonar Page.

•Advanced Data Fields — toggles On or Off the Advanced data fields on the Sonar Page

•Configure Advanced Data Fields — activates the Advanced Data Field Setup screen

Configuring Advanced Data Fields

The top left of the screen contains configurable data fields for the sonar display. By default, the Basic display shows the depth, water temperature and speed (depending on the Graph Tab settings and type of transducer/sensors attached). The ‘Configure Advanced Data Fields’ option in the Tools Tab allows you to customize the data fields that are displayed. The Advanced display shows a larger, configurable data field with a white background. The Data Field Setup screen allows you to specify the type of data displayed and either a Narrow (Small) or Wide (Larger) size format for each data field.

The following selections require the proper NMEA data (see pgs. 5-6) in order to display information in a data field: Bearing, Compass, Course, Distance to Next, Off Course, Pointer, Position, Speed, Time Of Day, Track, Turn, and VMG. NMEA Input/Output must also be enabled to receive this data (see pg. 20).
