User Manual
1. Overview
The Fish Finder consists of a high power transmitter, sensitive receiver and a
transducer. The Fish Finder sends an electrical pulse to the transducer which
contains an element that converts the pulse into acoustic (sound) wave which
is sent through the water. As this wave travels from the transducer to the
bottom, it may strike fish, structures, thermoclines (temperature changes in
the water). When the wave strikes an object(s) a certain amount of the wave
is reflected back to the transducer depending on the composition and shape
of the object. When the reflected wave is returned to the transducer it is
converted into an voltage and is amplified by the receiver, processed and
sent to the display. The speed of sound in water is roughly 4800 ft./sec, so
the time lapse between the transmitted signal and the received echo can be
measured and the distance to the object determined.

Warning Message
Flashing label "Simulation" when the echo sounder is in Simulation mode.
Echogram window
Graphic presentation of sonar soundings recorded as a continuous profile
scrolling across the screen from right to left. Such recordings represent
the image of the water beneath your boat, items appear as they pass
under your transducer; the items on the right side of the screen are
closer to you than those on the left. The correct interpretation of the
Echogram allows retrieving useful information about what is under the
boat. See the following Par. 2.1.1 for more information.
Color Bar
Colored scale located on the left side of the screen that shows the colors
used in the Echogram to represent the echoes strength. The color on the
top of the bar represents the maximum sonar strength, while the color on
the bottom of the bar represents the minimum sonar strength.

12 User Manual
Digital Depth
Readout of the current bottom depth.
Water Temperature
Readout of the current water temperature returned by the TEMP 1 sensor
included into specific transducers.
Alarm Bar
Bars showing the shallow water and deep water alarm values. The alarm
is triggered when depth is outside the range.
Depth ruler
Vertical graduated bar. It is a scale which reflects the depth of the area
being displayed.
Variable Depth Marker (VDM)
Horizontal line on to the Echogram window with a depth label. The up/
down cursor keys can move it up and down. The label displays the depth
of the cursor position. It can be moved to any location pinpointing the
depth of a target.
Zoom Bar
Bar showing the portion of the Echogram currently represented in the
zoomed window (on the left part of the screen). It is turned on selecting
Echo Sounder display page.
A-Scope
A real time representation of fish and bottom features passing through
the beam of the transducer. It is drawn as horizontal lines whose length
and hue is proportional to the sonar strength returned. When the default
palette is selected, the strongest sonar returns will be shown as the color
displayed of the top of Color Bar while the weakest as the bottom color.
Operating Frequency

Fig. 2.1.1 - The Fish Finder Echogram
Fishes
Fishes are represented as arcs because of the cone angle of the trans-
ducer. In fact as the boat passes over the fish the leading edge of the

13
User Manual
cone strikes the fish, causing a display pixel to be turned on. As the boat
passes over the fish, the distance to the fish decreases turning each pixel
on at a shallower depth on the display. When the boat is directly over the
fish, the first half of the arch is formed and since the fish is closer to the
boat, the signal is stronger and the arch is thicker. As the boat moves
away from the fish, the distance increases and the pixels appear at pro-
gressively deeper depths forming the remaining half of the arch.
Thermoclines
Are the zones where two layers of different water temperatures meet.
The greater the temperature differential, the thicker the thermocline is
shown on the screen. Thermoclines are represented as horizontal stripes
of noise. They are very important for fishing since often many species of
game fish like to suspend in, just above, or just below the thermoclines.
White Line
The White Line shows the difference between hard, soft bottoms and even
distinguishes between fishes and structures located near the bottom. In
this way it is easier to tell the difference between a hard and soft bottom
and even to distinguish fishes and structures located nearby the bottom.
For example, a soft, muddy or weedy bottom returns a weaker echo that
is shown with a narrow white line while a hard bottom returns a strong
echo that causes a wide white bottom line.
Surface Clutter
Appears like noise at the top of the screen extending many feet below the
surface. It’s caused by many things, including air bubbles, bait fish, plankton
and algae.
Structures
Generally, the term “structure” is used to identify objects like wrecks and
weeds rising from the bottom.
Bottom Echo Profile
Bottom profile recorded by the Fish Finder. When the echo sounder is set
in auto-range mode it is automatically kept in the lower half of the screen.
Other Elements
Large anchoring cables are returned by the echo sounder as very long and
narrow arcs on the screen.

3.1.10.2 Scrolling Speed
Adjusts the chart scrolling rate. Note that the scrolling rate is limited by the
sound speed and the depth according with the following relation: the deeper
the setting, the slower the scrolling rate. 100% is the maximum possible.
3.1.10.3 White Line
Controls how the chart plotter displays information about the bottom type
(hard or soft).
3.1.10.4 Fish Symbols
This selection allows determining the graphical representation of underwater
suspended targets. See the following table.
Echo : shows echoes
Echo + Icon : shows the Fish icon and echoes
Echo + Icon + Depth: shows the Fish icon, depth values and the fish echoes
Echo + Depth : shows depth values
Icon : shows Fish icons
Icon + Depth : shows Fish icons and their depth (accordingly to currently selected depth unit)
The Fish icons displayed are among four different shapes depending on the
size of the Target (Small, Med, Big, Huge).
