Selecting Data For Nav Data Displays - Furuno FCV-1150 Operator's Manual

About the mix display
The mix display compares echo intensity be-
tween low and high frequencies, and displays
echoes from tiny fish in discriminative colors.
This is done by utilizing the fact that tiny fish
return a stronger echo against a high frequen-
cy rather than a low frequency. It works as fol-
lows.
• If a high frequency echo is stronger than the
corresponding echo on the low frequency,
the high frequency echo is displayed.
• If the low frequency echo is stronger than or
equal to the high frequency echo, it is less
likely to be a tiny fish and therefore is dis-
played in blue.
• If the echoes on both frequencies have the
intensity corresponding to reddish-brown or
red, they are displayed in reddish brown or
red. This is necessary to display the zero
line and bottom in reddish-brown or red.
• In other words, the echoes displayed in or-
ange thru light-blue are considered to be
tiny fish such as whitebait.

Zoom Mode: Select the zoom display to
show, among bottom lock, bottom zoom,
marker zoom, discrim 1/2 and discrim 1/3.
The fractions in "discrim" indicate the amount
of space the discrimination occupies on the
left half of the screen.
Target Echo: Set fishing objective. Normal is
for general purpose fishing. Surface is for de-
tecting surface fish. Pulse repetition rate is
higher than "Normal" on the 1kW and 2kW
transducers that are programmed into the
menu. Squid detects squid and other individ-
ual fish. These items are automatically set: Tx
