How Sonar Works
Sonar technology is based on sound waves. The 500 Series™ Fishfinder uses
sonar to locate and define structure, bottom contour and composition, as well
as depth directly below the transducer.
Your 500 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 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 Wor s

3How Sonar Wor s
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
(DualBeam PLUS™ models only
[587ci HD, 597ci HD])
Your 587ci HD/597ci HD Fishfinder 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.

Down Imaging™ Sonar
(Down Imaging™ models only
[587ci HD DI, 597ci HD DI])
Your 587ci HD DI/597ci HD DI Fishfinder
uses own Imaging™ technology. The own
Imaging™ transducer scans the water with
razor-thin, high-definition beams. The beams
are wide (side to side) but very thin front to
back.
The own Imaging™ beams can be operated
at two frequencies: 455 kHz (75°) or 800 kHz
(45°). Select 455 kHz for the best overall
image quality and depth. Select 800 kHz for
the sharpest image. See Sonar Menu Tab:
Imaging Frequency for more information.
The transducer also uses conical beams to
provide data in traditional 2 format (see
What’s on the Sonar Display). Select 455 kHz
for a narrowly focused 16° center beam, or
select 200 kHz for a wider 25° beam (see Sonar
Menu Tab: Beam Select).
epth capability is affected by such factors
as boat speed, wave action, bottom hardness,
water conditions, and transducer installation.

Xtreme Depth Sonar
(Xtreme Depth Series™ models only [597ci HD XD])
Your 597ci HD XD Fishfinder uses the X
transducer to provide extreme depth coverage
with ualBeam PLUS™ technology.
The Xtreme epth sonar beams can be operated
at two frequencies: 50 kHz (74°) and 200 kHz
(20°). The wide, 50 kHz beam transmits at a low
frequency to provide greater depth coverage, up
to 2500 ft (762 m). The narrow, 200 kHz center
beam transmits at a high frequency to provide
maximum detail at shallower depths.
The ualBeam PLUS™ technology allows you to
view the sonar returns blended together,
separately, or side-by-side (see Sonar Menu
Tab: Beam Select and Views for more
information).
epth capability is affected by such factors as
boat speed, wave action, bottom hardness,
water conditions and transducer installation.

Dual Beam Ice T ansduce
(with optional-purchas XI 9 20 Ic
Transduc r)
he XI 9 20 Ice ransducer provides
selectable dual-frequency sonar with a
wide area of coverage. Selectable dual-
frequency gives you the option of two
beams, and both beams will cover the
bottom and provide high definition. he
20° center beam provides the highest
definition, while the 60° beam provides
wider coverage. Depth capability is
affected by such factors as bottom
hardness and water conditions. Whether
fishing in shallow or very deep water,
selectable dual-frequency is ideal for a
variety of conditions.

Center to etermine which accessory
trans ucers are compatible with your
Humminbir ® Fishing System, or visit our

How GPS Works
Your 500 Series™ Fishfinder also supports GPS (Global Positioning System) and
chartplotting. It uses GPS and sonar to determine your position, display it on a
grid, and provide detailed underwater information.
GPS uses a constellation of satellites that
continually send radio signals to the earth. 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.
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 Navigations Overlay Service),
and MSAS (the MTSAT Satellite Augmentation System) satellites if they are
available in your area.
The following GPS functionality is currently supported by the 500 Series™
Fishfinder 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
See Chart View and SD Memory Card Slot: Add Maps to Your Fishfinder for
more information.
