7.19 Fish Finder Menu
This section describes the fish finder functions not described in previous sections.
Open the home screen, then tap [Settings]→[Fish Finder].
[Fish Finder Source]: Set the fish finder to use (TZTL12F, TZTL15F, BBDS1, DFF1,
DFF3, DFF1-UHD). When using the built-in fish finder, select [TZTL12F] or [TZ-
TL15F], as applicable. You can switch the fish finder source with [Fish Finder Source]
in the [FISH FINDER INITIAL SETUP] section.
[Day Background Color]: Select the background color for use during daylight hours.
The options are [White], [Light Blue], [Black], [Dark Blue], and [Blue].
[Night Background Color]: Select the background color for use at nighttime. The op-
tions are [Black], [Dark Blue], and [Blue].
[Echo Color Levels]: Select the number of colors shown on the screen. The selec-
tions are [8 Colors], [16 Colors] and [64 Colors].
[Cancel Smoothing]: When you select [OFF], smoothed echoes are displayed, how-
ever, the screen resolution is lower. To get higher screen resolution and greater detail,
select [ON].
[Bottom Search Mode]: This function eliminates the timing of acquiring echoes from
the bottom, in order to improve the fish finder performance in the water layer. When
turned ON, transmission is turned off once every three transmissions to check the wa-
ter depth and eliminate false echoes. When turned off, transmission is not turned off,
so the transmission cycle is 1.5 times faster. This is convenient for offshore lure fish-
ing. You can also set this item from the Layers menu.
