•Tools—controls the appearance of useful sonar tools. The following options are available:

A-scope—when you turn on A-scope, a vertical flasher bar appears on the far-right side of the screen. This flasher indicates structure and bottom returns much the same as the Flasher Page. The horizontal width of the A-scope signal indicates the strength of the signal.

Color Bar—shows a gradient scale of the current Color Gain setting (see page 35).

Temp Graph—appears only if you have a temperature- capable transducer. This setting toggles the temperature graph along the bottom of a Sonar Page on or off. When on, the temperature graph matches the scrolling data.

•Split When Zoomed—splits the screen when you use the Zoom option. If you turn on Zoom, then this setting splits the screen. If Zoom is Off and you turn on Split When Zoomed, the last used zoom level is used on the screen.

•Swap Split—available on the Split Sonar Page when Frequency is set to Dual. This switches on which side the frequencies appear.

Using the Fishfinder 340C > Configuring Advanced Data Fields

Configuring Advanced Data Fields

The top-left corner of the screen contains configurable data fields for the Sonar Pages. You can view basic or advanced data for these data fields. By default, the Basic configuration shows the depth, water temperature, and speed (depending on the Graph tab settings and the type of transducer or sensors attached). The Advanced configuration shows a larger, configurable data field with a white background. The Advanced Data Setup Menu allows you to specify the type of data shown and either a Narrow (small) or Wide (larger) size format for each data field.
