How Sonar Works

Sonar technology is based on sound waves. The 700 Series™ Fishing System
uses sonar to locate and define structure, bottom contour and composition, as
well as depth directly below the transducer.

Your 700 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 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.

531519-1_A - 797c2_Man_Eng.qxp 11/6/2006 5:50 AM Page 1

2

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.

Side Imaging Sonar

Your 700 Series™ Fishing System uses Side
Imaging sonar to provide a wide yet precise
survey of a large area of water, including detailed
bottom topography and fish-attracting structure
orientation. The Side Imaging transducer returns
are processed into an image similar to an aerial
photograph. Typically, the Side Imaging sonar
searches an area that is 360 feet wide to each
side, 720 feet total side coverage, with a depth
limitation of 150 feet. See What’s on the Side

Imaging Display and Understanding Side
Imaging for more information.

DualBeam PLUS™ Sonar

Your 700 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.

QuadraBeam PLUS™ Sonar

(with optional-purchase QuadraBeam PLUS™
transducer)

Your 700 Series™ Fishing System also
supports QuadraBeam PLUS™ sonar with
the purchase of an additional QuadraBeam
PLUS™ transducer. QuadraBeam PLUS™
sonar provides an extremely wide 90° area
of coverage. QuadraBeam PLUS™ starts
with two fan-shaped 35° 455 kHz Side
Structure locating sonar beams to spot fish,
bait and structure to the left and right of the
boat over an area of the bottom that’s
always equal to twice your depth. For a
detailed view below the boat, QuadraBeam
PLUS™ uses DualBeam PLUS™ technology,
with precision 20° and wide 60° beams.
QuadraBeam PLUS™ finds more fish faster,
and can even tell you where to put your bait
by showing if fish are to the left, right or
directly beneath your boat.

Universal Sonar 2

Your 700 Series™ Fishing System supports Universal Sonar 2, a state-of-the­art, integrated and protected transducer that is built into the lower unit of
Minnkota trolling motors. With Universal Sonar 2, all wiring is concealed inside
the indestructible composite shaft—out of sight and out of harm’s way, with
no clamps, ties, or exposed wires. Universal Sonar 2 features new temperature
sensing and the performance of DualBeam PLUS™ technology (available with
all Humminbird® DualBeam PLUS™ models). An expanded view and greater
bottom detail gives you a totally new perspective of the water below, along
with optimal sonar performance to help you find fish.

How GPS and Cartography Work

Your 700 Series™ Fishing System also supports GPS and chartplotting, and
uses GPS and sonar to determine your position, display it on a grid, and provide
detailed underwater information. The Global Positioning System (GPS) is a
satellite navigation system designed and maintained by the U.S. Department of
Defense. GPS was originally intended for military use; however, civilians may
also take advantage of its highly accurate position capabilities, typically within
+/- 10 meters, depending on conditions. This means that 95% of the time, the
GPS receiver will read a location within 10 meters of your actual position. Your
GPS Receiver also uses information from WAAS (the Wide Area Augmentation
System), EGNOS (the European Geostationary Navigation Overlay Service), and
MSAS (the MTSAT Satellite Augmentation System) satellites if they are
available in your area.

GPS uses a constellation of 24 satellites that
continually send radio signals to the earth. Your
present position is determined by receiving signals
from up to 16 satellites and measuring the
distance from the satellites.

531519-1_A - 797c2_Man_Eng.qxp 11/6/2006 5:50 AM Page 5

6

All satellites broadcast a uniquely coded signal once per second at exactly the
same time. The GPS receiver on your boat receives signals from satellites that
are visible to it. Based on time differences between each received signal, the
GPS receiver determines its distance to each satellite. With distances known,
the GPS receiver mathematically triangulates its own position. With once per
second updates, the GPS receiver then calculates its velocity and bearing.

The GPS Receiver included with your 700 Series™ Fishing System allows you
to combine easy-to-use FishingGPS® chartplotter and navigation capabilities
with advanced fishfinding.

The following GPS functionality is currently supported by the 700 Series™
Fishing System when it is connected to the included GPS receiver:

• View current position

• View current track (breadcrumb trail)

• View precision speed and heading from your GPS receiver

• Save tracks, waypoints and routes

• Travel a route and navigate from one waypoint to the next.

Your 700 Series™ supports Navionics® Gold, HotMaps™ and HotMaps™ Premium
on MMC or SD card media.

NOTE: Your 700 Series™ does not support Navionics® Classic Charts, only Navionics® Gold,
HotMaps™, and HotMaps™ Premium.

Your unit also comes with a built-in Uni-Map™ with a more detailed map of
North America (Domestic models) or a more detailed map of Europe and
Southeast Asia, including Australia and New Zealand (International models).

Your 700 Series™ uses the GPS Receiver to determine the position of the boat
automatically, and uses the zoom level settings on a particular view to select
the best chart to display. See Viewing Cartography for more information.

Multi-Media Card
(MMC)/SD Slot

Your 700 Series™ Fishing System also has a
multi-media card (MMC)/SD slot that is used to
insert optional-purchase cards containing
additional detailed maps. If you insert an
MMC/SD that contains a more detailed chart for

a particular location, your 700 Series™ Fishing
System will retrieve that chart and display it automatically. Use the illustration
to locate the position of the MMC/SD slot cover, remove the MMC/SD slot
cover, then insert the MMC/SD into the slot. The label on the MMC/SD should
face toward the right side of the unit. Press down on the card until it clicks into
place, then replace the slot cover, making certain that the gasket is present and
positioned correctly before re-installing the cover, then replace and tighten
snugly - do NOT overtighten, as this will not improve water resistance, and may
damage the cover.

Software Updates

Use the MMC/SD slot to update the software version of your control head. To
update the software in your control head, plug in the appropriate MMC/SD card
that contains a software update file; the unit will recognize it, will tell you what
software version your control head is currently running, and will ask you if you
want to update the software in the unit to match that on the MMC/SD card.
You can obtain software updates from the www.humminbird.com website.

Understanding Side Imaging

It is important to understand how Side Imaging technology produces the
display. The images you see on the display are produced using sonar
technology. The special transducer produces three distinct beams – one beam
facing down and two beams pointing out to the side. These “side beams” are
aimed at right angles to the path of the boat and, unlike the “down beam”
which provide conical coverage, the side beams provide coverage which is very
thin front to back, yet very wide top to bottom.

The narrow aspect (front to back) of the beam illuminates a small strip of the
bottom perpendicular to the direction of the boat. Each time the unit “pings”,
a strip of data representing all the echoes received by the transducer, are put
together on the display to form the image that you see. The rows closest to the
boat icon at the top of the display are the most recent sonar data. The
information is scrolled down the screen as new data, drawn at the top of the
screen, becomes available.

455 kHz provides maximum coverage with 180° total beam width

531519-1_A - 797c2_Man_Eng.qxp 11/6/2006 5:50 AM Page 8

9

The side beams operate at a frequency of 455 kHz. It is important to understand
that when the boat turns, the strips to one side will begin to overlap and the
strips on the other side will fan out, providing some distortion to the image.
Side beams look out 360 feet to each side, with a total side coverage of 720 feet,
with a depth limitation of 150 feet, depending on the contour of the bottom.
Please see the side imaging sonar tutorial found on www.humminbird.com for
a more detailed explanation.

Your Side Imaging transducer also provides traditional sonar imaging at
200/83 kHz. Total coverage under the boat is 180°.

Upward slopes that face the transducer reflect sonar better than downward slopes that face

Shadows result from a lack of reflected
sonar from a particular area, and can be
more valuable for interpretation than
the sonar reflected by the object itself.
Use shadows to help you see the image
in 3 dimensions, oriented in space. You
can gain insight into the actual shape of
an object, or the depth to which it has
sunk into the bottom, through shadows
on the display.

Side Imaging Technology: How It Works

Side Imaging sonar uses two very precise sonar beams that are directed to
either side of the boat and “illuminate” the bottom contour, structure, and fish,
and display results in a “picture-like” image.

• Side beams are extremely narrow from front to back, and provide “thin
slices” of the bottom for high resolution imaging.

• Side beams look out to a range of 360 feet to each side, with a total side
coverage of 720 feet, with a depth limitation of 150 feet.

The main benefit of Side Imaging sonar to anglers is that it provides an overall
survey of a large area of water. This gives you a better understanding of the
bottom topography and how structure is oriented for more efficient fishing.
Saltwater anglers pick up precise details of popular fishing structure like
wrecks, reefs, humps and drop-offs, as well as being able to spot bait balls in
open water. Freshwater anglers can see fish-attracting structure such as
timber, stumps, rocks and creek beds.

Side Imaging: On the Water Interpretation

Use the following side imaging examples to help you interpret the side imaging
display.

Imaging Tips

Boat speed: Side imaging is best performed at boat speeds between 2 to 6
mph. If the boat is stationary, the same information is displayed over and over.
If the boat is moving very quickly, there will be gaps between the strips of
information. The best boat speed to use will depend on the side range
selected. Slower speeds are good for longer ranges, while faster speeds can
be used at shorter ranges.

Boat navigation: It is important to understand that when the boat turns,
successive beam strips to one side will begin to overlap and the strips on the
other side will fan out, providing some distortion to the image. Because of this,
the best imaging performance is produced by straight line navigation and
minimal side-to-side boat motion (i.e. wave induced, etc.) This applies to
navigation by either the main engine or the trolling motor. Minimize turning
time and avoid wave action that induces large side-to-side rocking of the boat.
For example, if there is a lot of wave activity, try to move the boat so that it is
perpendicular to the waves instead of parallel with the waves in order to
minimize the side-to-side rocking of the boat.

Beam Coverage: When there is an area directly under the boat that does not
have SI beam coverage, this area will be covered by the standard 200/83 kHz
down-looking beam and displayed in the Sonar views. The net effect of this, on
the display, is that a single object may appear as two separate entities, when
in reality, it is one continuous object. See Submerged Bridge: A Closer
Perspective and the Submerged Bridge: Alternative Perspective graphics for
examples of this.

What’s On the Sonar Display

The 700 Series™ Fishing System can display a variety of useful information about the a

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 or GPS Receiver.

Distance - Distance traveled with Temp/Speed
Accessory or GPS Receiver.

Average Speed - Average speed reading with
Temp/Speed Accessory or GPS Receiver.

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.

Speed - if a Temp/Speed accessory or GPS
Receiver is attached, the Fishing System can
display the speed of the boat, and can keep a
Triplog of nautical or statute miles traveled.

NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either device
information from the GPS receiver will be displayed on the view.

Cursor - available in Freeze Frame and can be
positioned in the Sonar View to provide depth of a
sonar return and bottom depth below the cursor.

Cursor Dialog Box - indicates cursor depth on
the display and the depth of the bottom directly
below the cursor. The Latitude and Longitude of
the cursor position, the distance to travel to the
cursor position and the bearing to the cursor
position is shown with a GPS receiver. A
waypoint can be marked at the cursor position
for later retrieval and use with a GPS receiver.

RTS® (Real Time Sonar) Window

Structure - where fish may be hiding.

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.

83 kHz Blue Fish Symbol

Bait Ball

Fish - the Fishing System 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.
