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 a 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.

This chapter is intended to help you understand how the chart plotter with the
Fish Finder connected operates to improve your fishing.
2.1 UNDERSTANDING THE FISH FINDER PAGE
The display on chart plotters shows a history of time of the echoes received by
the transducer. The chart plotters have a menu that allows adjustments to receiver sensitivity, depth range and scrolling speed of the Fish Finder display.

The following is a short description of terms listed in the previous Fig. 2.1:
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.
User Manual
11
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
Bar located on the right side of the Depth Ruler, showing the shallow water
and deep water alarm values. The alarm is triggered when depth is outside
the range.
Depth Ruler
Vertical graduated bar located along the right side of the screen. 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 located on the left side of the Depth Ruler, showing the portion of the
Echogram currently represented in the zoomed window (on the left part of
the screen). It is turned On selecting the Echo Sounder Split 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
Readout of the selected operating frequency.

Fishes
Fishes are represented as arcs because of the cone angle of the transducer.
In fact as the boat passes over the fish the leading edge of the 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 progressively 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.
