If the depth indication is incorrect, you can change the sound speed
setting to compensate for the error.
Compensates for incorrect water temperature data. For example, if the
shown water temperature is two degrees higher than the actual tem-
perature, enter -2.0.
Set how the bottom edge is determined, by signal level or display col-
or.
• [Level]:Determine the bottom edge by signal level. When the meth-
od is [Color], bottom fish may be hidden in the bottom edge. With
[Level] the shape of the bottom echo may change depending on the
bottom contour of the bottom.
• [Color]: Determine the bottom edge by display color. When bottom
fish are well separated from the bottom, the bottom is displayed with
a straight line, making discrimination of bottom fish easier. Howev-
er, the bottom presentation may change depending on gain setting.
When [Bottom Lock Mode] is set to [Color], you can select the color (0-
63) to be judged as the bottom echo.
Turns the zero line (transmission line) on or off. When turned [On], the
transmission line disappears, which allows you to see fish echoes
near the surface clearly. The width of the transmission line changes
with transducer used and installation characteristics.
Adjusts the transmission line so that the line disappears when the [Ze-
ro Line Rejector] is turned on. For a long tail, increase the value. If the
transmission line does not disappear, lower the TX power.
Turn off to see fish echoes near the surface.
