F Positions of visible GPS satellites:
Outer circle is horizon
Inner circle is 45° elevation
Centre is directly above

9 Sonar fishfinding: Introduction
Sonar functions require an optional sonar
transducer to be installed and set up.
This section explains how to interpret the
sonar displays, when and why to use the
different frequencies and how fish are
detected and displayed.
It also describes Gain and Range and shows
examples of some of the different sonar
displays.
9-1 Using the Instrument
The Instrument uses a sonar transducer
attached to the hull. The transducer
generates an ultrasonic pulse (sound that is
above the hearing range of the human ear),
which travels down towards the bottom at
a speed of about 4800 ft/sec (1463 m/sec),
spreading out into a cone shape.
When the pulse meets an object, such as a
fish or the bottom, it is partly reflected back
up towards the boat as an echo.
The depth of the object or bottom is
calculated by the Instrument by measuring
the time taken between sending a pulse and
receiving the echo. When an echo has been
returned, the next pulse is sent.
The Instrument converts each echo into an
electronic signal, displayed as a vertical line
of pixels.
