Simulator Operation; What You See On-Screen - Humminbird 100SX Single Beam Operation Manual

HOW SONAR WORKS
Your Humminbird unit uses sonar to locate and define
underwater objects, define the bottom terrain, as well as
determine distance.
Sonar technology is based on sound waves. Your
Humminbird unit sends out a sound wave signal. With this
signal it determines distance by measuring the time
between the transmission of the sound wave and when
the sound wave is reflected off an object. Your
Humminbird 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' (70m) and back again in less
than 1/4 of a second. It is unlikely that your boat can
"outrun" this sonar signal.
The 100SX is a 200kHz, single-beam fishfinder. The 200 kHz frequency provides excellent sonar
resolution (the ability to distinguish small returns or returns which are close to the bottom), while
providing depth capabilities to 600' (185m). The shape of the sonar beam is symmetrical and
covers an area of approximately 24 degrees side to side and front to rear.
Actual depth capability depends on factors such as bottom hardness, water conditions, and
transducer installation. Units will typically read to deeper depths in fresh water than in salt water

SIMULATOR OPERATION

The 100SX contains a simulator which allows you to use the unit as
if you are on the water. The Simulator is invaluable for learning how
to operate the many features of the 100SX. There are two ways to
enable the simulator: if the unit is powered off, press and hold the
POWER button
for approximately 3 seconds until a continuous chirp is heard. The Simulator can also be enabled
by selecting the Simulator option on the start-up screen after you normally powerup the unit.
When this screen is shown, simply press the DOWN ARROW until "Simulator" is highlighted.
When the screen times-out, the unit will be in simulator mode.
When in simulator operation, the 100SX responds to control inputs as if it is in actual operation,
so feel free to experiment with the many features and functions to customize the 100SX for your
particular operation. To exit Simulator mode, power the unit off.

WHAT YOU SEE ON-SCREEN

Your 100SX uses a 128 x 64 matrix FSTN LCD display. This type of display provides outstanding
viewability in all light conditions over a wide range of temperatures.
NOTE: When in simulator mode, the word "simulator" occasionally scrolls across the display
indicating that the information on-screen is not real sonar data.
At power-up, the depth range , sensitivity, and other user adjustments are set at their default
settings. There are several elements on-screen which are common to all modes of operation. The
