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 LC screen.
Each time a new echo is received, the old
echoes are moved across the LC , creating a
scrolling effect.
How Sonar Works

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.
How Sonar Works

DualBeam PLUS™ Sonar
Your 700 Series™ Fishing System uses a
200/83 kHz ualBeam PLUS™ sonar system with
a wide (60°) area of coverage. ualBeam 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. ualBeam PLUS™ sonar
returns can be blended together, viewed
separately, or compared side-by-side. ualBeam
PLUS™ is ideal for a wide range of conditions -
from shallow to very deep water in both fresh
and salt water. epth capability is affected by
such factors as boat speed, wave action, bottom
hardness, water conditions and transducer
installation.
How Sonar Works

QuadraBeam PLUS™ Sonar
(with optional-purchase QuadraBeam LUS™
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 ualBeam 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.

WideSide® Sonar
(with optional-purchase WideSide®
transducer)
Your 700 Series™ Fishing System also
supports WideSide® sonar with the
purchase of an additional WideSide®
transducer. The WideSide® transducer is a
specialized "side-looking" transducer that
is extremely useful for bank fishing or
looking for bait fish in open water. The
WideSide® transducer uses three different
sonar elements that transmit signals to the
left, right, and straight down from your
boat. The downward beam is 200 kHz with
a 24° area of coverage. This beam
maintains a continuous digital depth
readout from the bottom directly beneath
your boat. The side beams are 455 kHz with
a 16° area of coverage. The side-looking
elements can be used independently or
together to locate targets near the surface
of the water on either side of your boat.
Universal Sonar 2
(compatible with optional-purchase Minnkota trolling motors)
Your 700 Series™ Fishing System supports Universal Sonar 2, a state-of-the-
art, 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 ualBeam PLUS™ technology (available with
all Humminbird® ualBeam 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 Sonar Works

6
How GPS and Cartography Work
Your 700 Series™ Fishing System also supports GPS and chartplotting. It 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. epartment of
efense. GPS was originally intended for military use; however, civilians may
also take advantage of its highly accurate position capabilities, typically within
+/- 4.5 meters, depending on conditions. This means that 95% of the time, the
GPS receiver will read a location within 4.5 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 over 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.
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.
How GPS and Cartography Work

7
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 S card media. You can insert optional-purchase cards in
the (MMC)/S slot on your control head to access additional detailed maps.
See Multi-Media Card (MMC)/SD Slot for more information.
NOTE: Your 700 Series™ supports Navionics® Gold, HotMaps™, and HotMaps™
Premium. Your 700 Series™does not support Navionics® Classic Charts or Platinum™
Cartography.
Your unit also comes with a built-in UniMap™ with a more detailed map of
North America ( omestic 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 it uses the zoom level settings on a particular view to select
the best chart to display. See Chart View: Viewing Cartography for more
information.
