the reception of the reflected sound wave, the depth to the object can
be determined.
The entire process begins in the display unit. Transmitter power is
sent to the transducer as a short pulse of electrical energy. The elec-
trical signal produced by the transmitter is converted into an ultra-
sonic signal by the transducer and transmitted into the water. Any
reflected signals from intervening objects (such as a fish school)
are received by the transducer and converted back into an electri-
cal signal. It is then amplified in the amplifier section, and finally,
displayed on the screen.
The picture displayed is made up of a series of vertical scan lines
(pings), one for each transmission. Each line represents a ‘snapshot’
of what has occurred beneath the boat. The series of snapshots are
accumulated side by side across the screen, and the resulting contours
of the bottom and fish between the bottom and surface are displayed.
Selecting echosounder displays
The CX34/44/54 provides various types of echosounder displays:
standard echogram, bottom expansion (zoom), VRM expansion, and
shift mode. Each display has its special advantages. Select the appro-
priate setup for the echosounder display in the presentation “Setup”
and “Echosounder setup” displays, considering current sea area and
target fish.
