Power On
Follow the instructions below to power on your Humminbird® control head.
1. Press the POWER/LIGHT key.
2. When the Title screen is displayed, press the MENU key to access the
Start-Up Options Menu.
3. Use the 4-WAY Cursor Control key to select Normal (if there is a
transducer attached to the control head), or Simulator (if there isn’t a
transducer attached to the control head).
N TE: See Start-Up ptions Menu for more information.
•If a functioning transducer is connected, Normal operation will be
selected automatically at power up, and your Fishfinder can be
used on the water.
•If a transducer is not connected and you wait too long to select a
Start-Up Option, the system will default to whichever menu is
already highlighted.
• In Simulator you can learn how to use your control head and save
settings in advance for later use.

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

3
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 [386ci])
Your 386ci ishfinder 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 Wor s

5
Down Imaging™ Sonar
(Down Imaging™ models only [386ci DI])
Your 386ci DI ishfinder 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.

Dual Beam Ice Transducer
(optional-purchase XI 9 20 Ice Transducer only)
The XI 9 20 Ice Transducer 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. The 20
degree center beam provides the highest
definition, while the 60 degree beam
provides wider coverage. epth capability
is affected by such factors as bottom
hardness and water conditions. Whether
fishing in shallow to very deep water,
selectable dual-frequency is ideal for a
variety of conditions.

How GPS Works
Your 300 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.
ith distances known, the GPS receiver
mathematically triangulates its own position. ith
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 AAS (the ide 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.
The following GPS functionality is currently supported by the 300 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 SD Card Slot,Chart View, and Introduction to Navigation for more
information.
