The GP-1850DF/1850F takes about 90 seconds to find its position when turned on for
the very first time. This is because the equipment has no satellite data, called the Almanac, in its database. If you want to lessen
the time needed to find position you may
enter your position manually (default position: San Francisco, USA) on the GPS
SETUP OPTIONS menu.
Thereafter it takes about 12 seconds to find
position each time the power is turned on.
When the satellite signal is being received
normally, the GP-1850DF/1850F displays
various abbreviations at the bottom left-hand
corner of the display which show DGPS/GPS
receiver status. Table 1-1 shows these abbreviations and their meanings.

2. VIDEO SOUNDER OPERATION
2.1 Principle of Operation
The video sounder determines the distance
between its transducer and underwater objects such as fish, lake bottom or seabed and
displays the results on screen. It does this
by utilizing the fact that an ultrasonic wave
transmitted through water travels at a nearly
constant speed of 4800 feet (1500 meters)
per second. When a sound wave strikes an
underwater object such as fish or sea bottom, part of the sound wave is reflected back
toward the source (transducer). Thus by calculating the time difference between the
transmission of a sound wave and 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 electrical signal produced by the transmitter is
converted into an ultrasonic signal by the
transducer and transmitted into the water. Any
returning signals from intervening objects
(such as a fish school) are received by the
transducer and converted into an electrical
signal. The signals are then amplified in the
amplifier section, and finally, displayed on
screen.
The picture displayed is made up of a series
of vertical scan lines, one for each transmission. Each line represents a snapshot of what
has occurred beneath the boat. A 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.

50 kHz picture
The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency of the pulse, the wider the detection
area. Therefore, the 50 kHz frequency is useful for general detection and judging bottom
condition.
200 kHz picture
The higher the frequency of the ultrasonic
pulse the better the resolution. Therefore, the
200 kHz frequency is ideal for detailed observation of fish school.

This mode expands bottom and bottom fish
echoes two to five times to vertical size of
the screen, and is useful for determining bottom hardness. A bottom displayed with a short
echo tail usually means it is a soft, sandy
bottom. A long echo tail means a hard bottom.

Operation
Automatic sounder operation is useful when
you are preoccupied with other tasks and do
not have time to adjust the display.
How the automatic sounder works
The automatic sounder function automatically
selects the proper gain, range scale and clutter suppression level according to depth. It
works as follows:
• Range changes automatically to locate the
bottom on the lower half of screen. It jumps
to one step shallower range when bottom
echoes reach a half way point of the full
scale from top and to one step deeper
range when they come to the lower edge
of scale.
Dual-frequency display: Press the soft
key MODE.
Figure 2-14 Mode/frequency window
2. Press ▲ or ▼ to select AUTO CRUISING
or AUTO FISHING.
3. Press the soft key RETURN to close the
window automatically , or wait 10 seconds
and the window closes automatically.
2.6 Manual Sounder
Operation
• The gain is automatically adjusted to display the bottom echo in reddish brown (default color arrangement).
• Clutter, which suppresses low level noise,
is automatically adjusted.
Two types of automatic sounder
modes
Two types of automatic sounder modes are
available: CRUISING and FISHING. CRUISING is for tracking the bottom, and FISHING
is for searching fish schools. CRUISING uses
a higher clutter rejection setting than FISHING therefore it is not recommended for fish
detection - weak fish echoes may be erased
by the clutter suppression circuit.
How to enable automatic sounder
operation
Manual operation is useful for observing fish
schools and bottom using fixed gain setting.
The gain, range and range shifting functions
used together give you the means to select
the depth you can see on screen. The basic
range can be thought of as providing a “window” into the water column and range shifting as moving the “window” to the desired
depth.
Selecting the manual mode
1. Press the appropriate soft key to show
the mode/freq window.
2. Select MANUAL.
3. Press the soft key RETURN.
1. To show the mode/freq window:

The bottom-lock fish alarm sounds when a
fish echo is within a predetermined distance
from the bottom.
Fish (normal) alarm
The normal fish alarm sounds when a fish
echo is within the preset alarm range.
Note: The sensitivity of the fish alarm can be
set on the SOUNDER SYSTEM SETUP
menu.
Water temperature alarm
There are two types of water temperature
alarms: WITHIN and WITHOUT. The WITHIN
alarm sounds when the water temperature
is within the range set; the WITHOUT alarm
sounds when the water temperature is higher
or lower than the range set. This alarm requires water temperature data.
When an alarm setting is violated the buzzer
sounds, and the (red) speaker icon appears
at the bottom of the screen. You can silence
the buzzer with the [CLEAR] key. (However,
the buzzer will sound whenever the alarm setting is violated.) Press the [ALARM] key to
find out which alarm has been violated. The

2.15 Interpreting the Display
Bottom echo
Zero line
The zero line (sometimes referred to as the
transmission line) represents the transducer’s
position, and moves off the screen when a
deep phased range is used.
Zero

Shift
Figure 2-31Zero line
Fish school echoes
Fish school echoes will generally be plotted
between the zero line and the bottom. Usually the fish school/fish echo is weaker than
the bottom echo because its reflection property is much smaller compared to the bottom. The size of the fish school can be
ascertained from the density of the display.
Echoes from the bottom are normally the
strongest and are displayed in reddish-brown
color but the color and width will vary with
bottom composition, water depth, frequency ,
sensitivity, etc.
In a comparatively shallow depth, a high gain
setting will cause a second or sometimes a
third or a fourth echo to be displayed at the
same interval between them below the first
echo trace. This is because the echo travels
between the bottom and the surface twice or
more in shallow depths.
The color of the bottom echo can be used to
help determine the density of the bottom materials (soft or hard). The harder the bottom,
the wider the trace. If the gain is set to show
only a single bottom echo on mud, a rocky
bottom will show a second or third bottom
return. The range should be chosen so the
first and second bottom echoes are displayed
when bottom hardness is being determined.

Surface noise/Aeration
When the waters are rough or the boat
passes over a wake, surface noise may appear near the zero line. As surface turbulence
is acoustically equivalent to running into a
brick wall, the bottom echo will be displayed
intermittently. Similar noise sometimes appears when a water temperature difference
(thermocline) exists. Different species of fish
tend to prefer different temperature zones,
so the thermocline may be useful to help identify target fish. 200 kHz tends to show shallow thermoclines better than 50 kHz.
In rough waters the display is occasionally
interrupted due to below-the-ship air bubbles
obstructing the sound path. This also occurs
when the boat makes a quick turn or reverses
movement. Lowering the picture advance
speed may reduce the interruption. However ,
reconsideration of the transducer installation
may be necessary if the interruption occurs
frequently.
