How Sonar Works
Sonar technology is based on sound waves. The 300 Series™ Fishing System uses
sonar to locate and define structure, bottom contour and composition, as well as
depth directly below the transducer.
Your 300 Series™ Fishing System sends a sound wave signal and determines
distance by measuring the time between the transmission of the sound wave and
when the sound wave is reflected off of an object; it then uses the reflected signal
to interpret location, size, and composition of an object.
Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft
(70 m) and back again in less than 1/4 of a second. It is unlikely that your boat can
"outrun" this sonar signal.
SONAR is an acronym for SOund and
NAvigation Ranging. Sonar utilizes
precision sound pulses or "pings" which
are emitted into the water in a teardropshaped beam.
The sound pulses "echo" back from
objects in the water such as the bottom,
fish and other submerged objects. The
returned echoes are displayed on the LCD
screen. Each time a new echo is received,
the old echoes are moved across the LCD,
creating a scrolling effect.
1
When all the echoes are viewed side by
side, an easy to interpret "graph" of the
bottom, fish and structure appears.
The sound pulses are transmitted at
various frequencies depending on the
application. Very high frequencies (455
kHz) are used for greatest definition but
the operating depth is limited. High
frequencies (200 kHz) are commonly
used on consumer sonar and provide
a good balance between depth
performance and resolution. Low
frequencies (83 kHz) are typically used to
achieve greater depth capability.

The power output is the amount of
energy generated by the sonar
transmitter. It is commonly measured
using two methods:
• Root Mean Square (RMS) measures
power output over the entire transmit
cycle.
• Peak to Peak measures power output
at the highest points.
The benefits of increased power output are the ability to detect smaller targets at
greater distances, ability to overcome noise, better high speed performance and
enhanced depth capability.
DualBeam PLUS™ Sonar
Your 300 Series™ Fishing System uses a
200/83 kHz DualBeam PLUS™ sonar system
with a wide (60°) area of coverage.
DualBeam PLUS™ sonar has a narrowly
focused 20° center beam, surrounded by a
second beam of 60°, expanding your
coverage to an area equal to your depth. In
20 feet of water, the wider beam covers an
area 20 feet wide. The 20° center beam is
focused on the bottom, to show you
structure, weeds and cover. The 60° wide
beam is hunting for fish in the wide coverage
area. DualBeam PLUS™ sonar returns can be
blended together, viewed separately or
compared side-by-side. DualBeam PLUS™ is
ideal for a wide range of conditions - from
shallow to very deep water in both fresh and
salt water. Depth capability is affected by
such factors as boat speed, wave action,
bottom hardness, water conditions and
transducer installation.

What’s On the Display
The 300 Series™ Fishing System can display a variety of useful information about the area under and adjacent to your boat, including the following items:
Timer - elapsed time with Temp/Speed
Accessory.
Average Speed - average speed reading with
Temp/Speed Accessory.
Depth - water depth; can be set to alarm
when the water becomes too shallow.
Speed - if a Temp/Speed accessory is attached,
the 300 Series™ can display the speed of the
boat, and can keep a Triplog of nautical or
statute miles traveled.
Second Sonar Return - when the sonar
signal bounces between the bottom and the
surface of the water and back again. Use the
appearance of the second return
to determine bottom hardness. Hard
bottoms will show a strong second return,
while soft bottoms will show a very weak
one or none at all.
Cursor Dialog Box - indicates cursor depth on the display and the depth of the bottom
directly below the cursor.

Views
The views available on your 300 Series™ Fishing System are:
• Sonar View
• Zoom View
• 200/83 kHz Split Sonar View
• Big Digits View
• Circular Flasher View.
Sonar View is the default view. When the VIEW key is pressed, the display cycles
through the available views. When the EXIT key is pressed, the display cycles
through the available views in reverse order. Any view can be hidden or displayed as
part of the view rotation using the Views Menu tab.
NOTE: When you change any menu settings that affect the sonar, the view will update
immediately (i.e. you don’t have to exit the menu to apply the change to the screen). For
instance, by switching between "Inverse" and "Structure ID®" from the X-Press
TM
Menu it is
possible to quickly alternate between the two viewing methods.

Sonar View
Sonar View presents a historical log of sonar returns. Depth is always displayed.
Readouts for temperature and speed are automatically displayed if the appropriate
accessory is connected. The most recent sonar returns are charted on the right side
of the window; as new information is received, the older information is moved
across the display to the left. A Digital Depth Readout is displayed in the upper left
corner. A scale with Upper and Lower Depth Range readouts appears along the right
edge of the Sonar View. The scale indicates the distance from the surface of the
water to a depth range sufficient to show the bottom. Depth Range is automatically
selected to keep the bottom visible on the display, although you can adjust it
manually as well (see Sonar X-Press
TM
Menu). Five additional Digital Readouts display
information from optional-purchase accessories.
These information boxes can be customized to show only the information desired
(see Setup Menu Tab, Select Readouts).
NOTE: If the Depth number is flashing, it means that the unit is having trouble locating
the bottom. This usually happens if the water is too deep, the transducer is out of the
water, the boat is moving too fast, or for any other reason that the unit can’t accurately
receive continuous data.

Real Time Sonar (RTS®) Window
A Real Time Sonar (RTS®) Window appears on the right side of the display in the
Sonar View only. The RTS® Window always updates at the fastest rate possible for
depth conditions and shows only the returns from the bottom, structure and fish
that are within the transducer beam. The RTS® Window plots the depth and
intensity of a sonar return (see Sonar Menu - RTS® Window).
Freeze Frame
Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the
screen and a cursor will be displayed on the screen. The cursor can be positioned on
the display using the 4-WAY Cursor Control key to determine the depth of any sonar
return. The RTS® Window continues to update in Freeze Frame. In addition, see the
effects of menu setting changes with Instant Image Update. Pressing EXIT will exit
Freeze Frame and the display will start to scroll. Freeze Frame is available in Sonar,
Sonar Zoom and 200/83 kHz Split Sonar Views.
The Narrow RTS® Window
indicates the sonar intensity
through the use of grayscale.
The grayscale used matches
the bottom view grayscale
setting used in the sonar
history window (i.e. Inverse,
Structure ID®, WhiteLine®,
Bottom Black). The depth of
the sonar return is indicated
by the vertical placement of
the return on the display
depth scale.
The Wide RTS® Window
indicates the sonar intensity
through the use of a bar
graph. The length of the
plotted return provides an
indication of whether the
return is weak or strong. The
depth of the sonar return is
indicated by the vertical
placement of the return on
the display depth scale. The
Wide RTS® Window does not
make use of grayscale.
9
Understanding Sonar History
It is important to understand the significance
of the 300 Series™ Fishing System display. The
display does NOT show a literal 3-dimensional
representation of what is under the water. Each
vertical band of data received by the control head
and plotted on the display represents something
that was detected by a sonar return at a particular
time. As both the boat and the targets (fish) may be
moving, the returns are only showing a particular
segment of time when objects were detected, not
exactly where those objects are in relation to other
objects shown on the display.
531444-1_A - 323_Man_English.qxd 11/5/2005 12:33 PM Page 16
Inverse is a method where weak returns are shown
with dark pixels and strong returns with lighter pixels.
This has the benefit of ensuring that weak signals will
be clearly visible on the display.
Structure ID® represents weak returns as light pixels
and strong returns as dark pixels. This has the benefit of
ensuring that strong returns will be clearly visible on
the display.
WhiteLine® highlights the strongest sonar returns in
white, resulting in a distinctive outline. This has the
benefit of clearly defining the bottom on the display.
Bottom Black displays all pixels below the bottom
contour as black, regardless of signal strength. This has
the benefit of providing a high contrast between the
bottom and other sonar returns on the display. Any
targets such as fish, structure and thermoclines will be
shown using the Structure ID® method.
11
Bottom Presentation
As the boat moves, the unit charts the changes in depth on the display to create a profile
of the Bottom Contour. The type of bottom can be determined from the return charted
on the display. A Hard Bottom such as compacted sediment or flat rock appears as a
thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker
line across the display. Rocky Bottoms have a broken, random appearance.
The sonar returns from the bottom, structure and fish can be represented as either
Inverse (default), WhiteLine®, Structure ID®, or Bottom Black. See Sonar X-Press
TM
Menu: Bottom View for details on how to set the bottom view.

200/83 kHz Split Sonar View
Split Sonar View displays sonar returns from the 83 kHz wide beam on the left side
of the screen and displays sonar returns from the 200 kHz narrow beam on the right
side of the screen. Depth is always displayed in the upper left hand corner. You can
use the Split Sonar View to make side by side comparisons between the sonar
returns from the 83 kHz wide beam and the 200 kHz narrow beam.
The digital readouts in the Split Sonar View cannot be customized; therefore,
information such as water temperature and voltage are unavailable in the Split
Sonar View.

Sonar Zoom View
Sonar Zoom View increases the displayed resolution to separate sonar returns that
are very close together, such as those caused by fish suspended close to the bottom
or within structure. In Zoom View, the display is split to show a narrow slice of the
full range view on the right and the zoomed view on the left. The full range view on
the right also contains the Zoom Preview Box that shows what part of the full range
view is shown in zoom view on the left; the Zoom Preview Box tracks the bottom in
the full range view.
As the depth changes, the zoomed view updates automatically to display a
magnified image of the bottom. The Zoom Preview Box shows where the zoomed
view is in relation to the full range view. The Zoom Level, or magnification, is
displayed in the lower left corner and can be changed to suit conditions (see Sonar
X-Press
TM
Menu: Zoom Level). Upper and Lower Zoom Depth Range numbers indicate
the depth of the water which is being viewed.
Digital depth is displayed in the upper left hand corner. The digital readouts in the
Sonar Zoom View cannot be customized; therefore, information such as water
temperature and voltage are unavailable in the Sonar Zoom View.
