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
