the unit to use both frequencies at the same time (“dual frequency”), or even display both frequencies at once (“split screen”).
Auto frequency on (A)
An “A” indication here shows that the unit is choosing the frequency automatically. (For more on this, see “Choosing the Frequency.”)
Boat symbol This symbol is always turned on. It indicates that the new information appears at the right edge of the display, and the older information moves toward the left.
Center of display
Water surface This symbol (“0”) shows the depth indicated by the top of the display. Usually, this is the level of the surface of the water. (If the Zoom Mode is turned on, this will show the depth of the top of the zoom area.) The depth is shown using the same units as the rest of the display. This could be feet (FT), fathoms (FA), or meters (M), depend- ing on the setting you make in the System Setup Menu.
Depth markers
These markers show depths between the surface and the full depth range. In this example, the unit is set for a depth range of 100 feet. This means that each of the depth markers shows an interval of 20 feet.
Speed | This entry shows the speed of the boat through the water. |
| From the System Setup Menu, you can turn this item off or |
| change the units used for this display. |
Log/distance This shows how far the boat has traveled since the log was last reset. From the System Setup Menu, you can turn this item off or change the units used for this display.
Water temperature
This entry shows the current water temperature at the surface of the water. (The reading for water temperature can be helpful for finding fish. A particular type of fish will often prefer water in a narrow temperature range.)
