How Sonar Works
Sonar technology is based on sound waves. The 300 Series™ Fishfinder uses
sonar to locate and define structure, bottom contour and composition, as well
as depth directly below the transducer.
Your 300 Series™ Fishfinder 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 uses precision
sound pulses or “pings“ which are emitted
into the water in a teardrop-shaped 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.
2
How Sonar Works
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:
How Sonar Works
• 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. 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.

How Sonar Works
What’s On the Sonar Display
The 300 Series™ Fishfinder can display a variety of useful information about
Depth - Water depth; can be set to alarm when
the water becomes too shallow.
Temperature - Water surface temperature.
Timer - Elapsed time with Temp/Speed
Accessory.
Distance - Distance traveled with Temp/Speed
Accessory.
Average Speed - Average speed reading with
Temp/Speed Accessory.
Speed - If a Temp/Speed accessory is attached,
the Fishfinder 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
bouncesbetweenthebottom and thesurfaceof the
water and back again. Use the appearance of the
second return to determine bottom hardness. Hard

the area under your boat, including the following items:
High Sonar Intensity Return
Bait Ball
Fish - The Fishfinder displays fish as arches
and/or fish icons, and can be set to alarm
when a fish of a certain size is detected.
When a target is detected, a Fish ID+™
symbol appears on the display with the
depth displayed above it. The size of the
symbol indicates the intensity of the sonar
return. The unit will clearly show schools of
Bait Fish as "clouds" of different shapes and
sizes, depending on the number of fish and
boat speed.
Thermoclines - Layers of water with different
temperatures that appear at different depths
and different times of the year. A thermocline
typically appears as a continuous band of
many colors moving across the display at the
same depth.

What’s On the Sonar Display
UUnnddeerrssttaannddiinngg tthhee SSoonnaarr DDiissppllaayy
It is important to understand the significance of
the 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.
The returned sonar echoes are displayed on the screen. As a new echo is
received, the historical data scrolls left across the view.
RReeaall TTiimmee SSoonnaarr ((RRTTSS™™)) WWiinnddooww
A Real Time Sonar (RTS™) Window appears on the right side of the display in
the Sonar View only. The RTS Window™ 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 Tab: RTS Window™).
The Narrow RTS Window™
indicates the sonar intensity
through the use of colors. Red
indicates a strong return and
blue indicates a weak return.
The depth of the sonar return
is indicated by the vertical
placement of the return on the
display depth scale.
What’s On the Sonar Display
The Wide RTS Window™
indicates the sonar intensity
through the use of a bar
graph. The length of the
plotted return indicates
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 use
grayscale.

SSwwiittcchhFFiirree™™
SwitchFire™ controls how the sonar returns are displayed in the Sonar Views.
SwitchFire™ settings are available in the Sonar Menu Tab.
To see the maximum sonar information available within the transducer beam so
more fish arches and better jig tracking are shown, choose Max Mode.
To see less clutter and more fish size accuracy interpreted from the transducer
beam, choose Clear Mode. See Sonar Menu Tab: SwitchFire™ for more
information.

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.
