1.2 Installation of Standard Equipment
Installing the display unit
Mounting considerations
The display unit can be installed on a tabletop or on the overhead.
When selecting a mounting location for the display unit keep the
following in mind:
• Keep the display unit out of direct sunlight.
• The temperature and humidity should be moderate and stable.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the unit away electromagnetic field generating equipment
such as motor, generator.
• For maintenance and checking purposes, leave sufficient space
at the sides and rear of the unit and leave slack in cables.
• A gyrocompass will be affected if placed too close to the display unit. Observe the following compass safe distances to prevent disturbance to the gyrocompass:
Standard compass: 0.7 meters

Mounting considerations
When selecting a mounting location for the antenna unit, keep in
mind the following points:
• Select a location out of the radar beam. The radar beam will
obstruct or prevent reception of the GPS satellite signal.
• Be sure the location offers a clean line-of-sight to satellite. Objects within line-of-sight to a satellite, for example, a mast or
funnel, block reception and cause prolonged acquiring time or
interruption of position fix.
• Mount the unit as high as possible. This will keep the unit free
of water spray, which can interrupt reception of GPS satellite
signal if frozen.
• Separate the unit well away from the antenna of radio equipment.

Antenna unit mounting procedure
You will need a medium size slotted-head screwdriver and vinyl
tape.
The standard antenna is usually fastened to a length of pipe and
fastened to a mast. (A mast mount fixture is optionally available
for this.) The threaded antenna base accepts a standard antenna
mount with a 1"-14 straight thread. Mount the antenna on a length
of pipe with a 1"-14 threaded end.
1. Pass the antenna cable through the pipe. Fasten the connector
on the cable to the antenna.

unit to prevent interference. The grounding wire should be 1.25 sq
or larger and as short as possible. Connect the grounding wire to
ship's ground by silver-alloy brazing. On a fiberglass boat, it is
best to install a ground plate that measures about 20 cm by 30 cm
on the outside of the hull bottom to provide a ground point. If this
is not practical, the engine block can be used.

1.3 Installation of Transducers
Installing the inside-hull mount transducer
Necessary tools
You will need the following tools:
• Sandpaper (#100)
• Silicone sealant
• Silicone grease
Remarks on installation
• Do the installation with the boat hauled out of the water.
• Turn off the engine while installing the equipment.
• Install the transducer in the engine room.
Selecting the mounting location
Keep the following points in mind when selecting a mounting location:
• The mounting location should be where the hull is of singlehull thickness and is void of air or flotation materials other than
solid fiberglass between the transducer face and the water.
• Do not place the transducer over hull struts or ribes which run
under the hull.
• Avoid a location where the rising angle of the hull exceeds 15°,
to minimize the effect of the boat’s rolling.
• You will finalize the mounting location through some trial and
error. The procedure for this is shown later.

If the bottom is displayed in red and the light-blue color appears
the mounting location is suitable. You can leave the transducer
in position.
If the bottom is not displayed in reddish brown, the mounting
location is unsuitable. Relocate the transducer and do the
following.
1. Press the POWER key to turn off the power.
2. Gently dismount the transducer with piece of wood.
3. Do steps 1 through 5 in the previous procedure. Repeat until
a suitable location is found.
Final preparation
Support the transducer with a piece of wood to keep it in place
wile it is drying. Let the transducer dry 24–72 hours.
1-13
Installing the thru-hull mount transducer
Transducer mounting location
This type of mounting provides the best performance of all, since
the transducer protrudes from the hull and the effect of air bubbles
and turbulence neat the hull skin is reduced. When the boat has a
keel, the transducer should be at least 30 cm away from it. Typical
through hull mountings are shown in the figure on the next page.
The performance of the video sounder is directly related to the
mounting location of the transducer, especially for high-speed cruising. The installation should be planned in advance, keeping the
standard cable length (8 m) and the following factors in mind:
• Air bubbles and turbulence caused by movement of the boat
seriously degrade the sounding capability of the transducer. The
transducer should, therefore, be located in a position where water flow is the smoothest. Noise from the propellers also adversely affects performance and the transducer should not be
mounted nearby. The lifting strakes are notorious for creating
acoustic noise, and these must be avoided by keeping the transducer inboard of them.
• The transducer must always remain submerged, even when the
boat is rolling, pitching or up on a plane at high speed.
• A practical choice would be somewhere between 1/3 and 1/2 of
the boat's length from the stern. For planing hulls, a practical
location is generally rather far astern, so that the transducer is
always in water regardless of the planing attitude.

Procedure for installing the thru-hull mount transducer
1. With the boat hauled out of the water, mark the location selected for mounting the transducer on the bottom of the hull.
2. If the hull is not level within 15° in any direction, fairing blocks
made out of teak should be used between the transducer and
hull, both inside and outside, to keep the transducer face parallel with the water line. Fabricate the fairing block as shown
below and make the entire surface as smooth as possible to
provide an undisturbed flow of water around the transducer.
The fairing block should be smaller than the transducer itself
to provide a channel to divert turbulent water around the sides
of the transducer rather than over its face.

Figure 1-22 Construction of fairing block
3. Drill a hole just large enough to pass the threaded stuffing tube
of the transducer through the hull, making sure it is drilled vertically.
4. Apply a sufficient amount of high quality caulking compound
to the top surface of the transducer, around the threads of the
stuffing tube and inside the mounting hole (and fairing blocks
if used) to ensure watertight mounting.
5. Mount the transducer and fairing blocks and tighten the locking nuts. Be sure that the transducer is properly oriented and its
working face is parallel to the waterline.
Note: Do not over-stress the stuffing tube and locking nuts through
excessive tightening, since the wood block will swell when the
boat is placed in the water. It is suggested that the nut be tightened
lightly at installation and retightened several days after the boat
has been launched.

Installing the transom mount transducer
This type of mounting is very commonly employed, usually on
relatively small I/O or outboard boats. Do not use this method on
an inboard motor boat because turbulence is created by the propeller ahead of the transducer.
There are two methods of installation: flush with hull (for flat hulls)
and projecting from hull (for deep V-hulls).

D>50 cm

Figure 1-23 Transom mount transducer mounting locations
Installing the transom mount transducer flush with hull (for
flat hulls)
A suitable mounting location is at least 50 cm away from the engine and where the water flow is smooth.
1. Drill four pilot holes in the mounting location.
2. Attach the transducer to the bracket with tapping screws (supplied).
3. Adjust the transducer position so the transducer faces right to
the seabed.
Note: If necessary, to improve water flow and minimize air
bubbles staying on the transducer face, incline the transducer
about 5° at the rear. This may require a certain amount of
experimentation for fine tuning at high cruising speeds.
4. Fill the gap between the wedge front of the transducer and transom with epoxy material to eliminate any air spaces.

Figure 1-24 Transom mount transducer, mounting flush with hull
Installing the transom mount transducer projecting from
hull (for deep-V hulls)
This method is employed on deep-V hulls and provides good performance because the effects of air bubbles are minimal. Install
the transducer parallel with water surface; not flush with hull. If
the boat is placed on a trailer care must be taken not to damage the
transducer when the boat is hauled out of the water and put on the
trailer.

Transducer preparation
Before putting the boat in water, wipe the face of the transducer
thoroughly with a detergent liquid soap. This will lessen the time
necessary for the transducer to have good contact with the water.
Otherwise the time required for complete "saturation" will be
lengthened and performance will be reduced.
Do not paint the transducer. Performance will be affected.

1.4 Installation of Optional Sensors
Through-hull mount water temperature/speed sensor
(ST-02MSB, ST-02PSB)
Select a suitable mounting location considering the following:
• Select a mid-boat flat position. The sensor does not have to be
installed perfectly perpendicular. The sensor must not be damaged in dry-docking operation.
• Select a place apart from equipment generating heat.
• Select a place in forward direction viewing from the drain hole
for cooling water.
• Select a place free from vibration.
1. Dry-dock the boat.
2. Make a hole of approx. 51 mm diameter.
3. Unfasten locknut and remove the sensor section.
4. Apply high grade sealant to the flange of the sensor.
5. Pass the sensor casing through the hole.
6. Face the notch on the sensor toward boat's bow and tighten the
flange.
7. Set the sensor section to the sensor casing and tighten the locknut.
8. Launch the boat and check for water leakage around the sensor.

VIDEO SOUNDER OPERATION
3.1 Principle of Operation
The video sounder of the GP-1610CF 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 source. Thus by calculating 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 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. Series of snapshots are accumulated side by side across
screen, and the resulting contours of the bottom and fish between the bottom and surface
are displayed.

3.2 Automatic Sounder
Operation
3.3 Manual Sounder
Operation
Automatic operation is useful when you are
preoccupied with other tasks and do not have
time to adjust the display.
Manual operation is useful for observing fish
schools and bottom using fixed gain setting.
How it works
The automatic function automatically selects
the proper gain and range scale 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.
• The gain is automatically adjusted to display the bottom echo in reddish brown (default color arrangement).
• Clutter level, (on the VIDEO SOUNDER
SETUP menu), which suppresses low level
noise, is automatically adjusted.
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 the range shifting
as moving the "window" to the desired depth.
Manually adjusting the sounder

Two types of automatic modes
Two types of automatic modes are available:
cruise and fish. Cruise is for tracking the bottom, and fish is for searching fish schools.
Since "Cruise" uses a higher clutter rejection
setting than "Fish," it is not recommended for
fish detection – weak fish echoes may be deleted by clutter rejection.

3.24 Interpreting the Display
Bottom echo
Zero line
Echoes from the bottom are normally the
strongest and are displayed in reddish brown
color (in default color arrangement) but the
color and width will vary with bottom composition, water depth, frequency, sensitivity,
etc.
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.
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.
Zero
line
Shift
Figure 3-21 Zero 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.
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, 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 zone, 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.

GPS, CHART OVERVIEW
How the GPS receiver calculates
position
4.1 Principle of GPS
What is GPS?
The GPS receiver’s position is continuously
fixed by receiving 3 (or 4) satellites in lineof-sight of the GPS receiver. The basic steps
in position fixing are as below:
GPS is an acronym meaning Global Positioning System. GPS (sometimes referred to as
NAVSTAR) is a highly precise satellite navigation system developed by the U.S. Department of Defense.
1) GPS satellites continually transmit their
own precise orbital data called ephemeris.
The GPS receiver computes satellites’
position by this data.
A constellation of 24 satellites emplaced in
nearly 20,000-kilometer high 12-hour circular orbits provides highly precise, continuous,
worldwide, all-weather position plus time and
velocity information to GPS receiverequipped vehicles, vessels and aircraft.
2) The GPS receiver measures very accurate
distance to the satellites.
3) Satellite positions and their distances from
the GPS receiver are known. The point of
intersection of the satellites used in fixing
position.
1 Satellite locations are
calculated.
2 Distances are measured.
3 The GPS fix is the point
of intersection of three
spheres which are drawn
around the three satellites
with diameter d1, d2, and d3.

Figure 4-1 How GPS determines position
4-1
Position-fixing accuracy (HDOP)
In radar position-fixing, most accurate position fixes are obtained when the targets used
are spaced nearly 90° from each other. Similarly, GPS position fixing accuracy is subject
to satellite location. Generally, the further
apart the satellites are from one another, the
greater the position-fixing accuracy.
For example, take a look at Figure 4-2. In both
situations a fix is obtainable in the Northern
Pacific region because three satellites are in
line-of-sight. However, accuracy will be
higher in the bottom figure since the satellites
are spread farther apart than the satellites in
the top figure.
The index for position-fixing accuracy is
known as HDOP (Horizontal Dilution of Precision). In simpler terms it is the geometrical
relationship among 3 (or 4) satellites. The
higher the HDOP value the less accurate the
position fix. The error in distance is proportional to the HDOP value as shown in Figure
4-3.

the waypoint under that number go to step
5. To change the number go to step 4.
7.1 Entering Waypoints
In navigation terminology, a waypoint is a
particular location on a voyage whether it be
a starting, intermediate or destination point.
A waypoint is the simplest piece of information the GP-1610CF requires to get you to a
destination, in the shortest distance possible.
This unit has 200 waypoints into which you
can enter position information. There are four
methods by which you can enter a waypoint:
• By ship's position
• Through the waypoint list (manual input
of latitude and longitude)
• By event position or MOB position
• By the cursor
4. Enter waypoint number with numeric
keys.
5. To select mark shape, press ▼. (If not selected the waypoint will be marked by a
yellow octagon with waypoint number in
its center. Waypoint color cannot be
changed.)

7.5 Entering Routes
Often a trip from one place to another involves
several course changes, requiring a series of
route points (waypoints) which you navigate
to, one after another. The sequence of
waypoints leading to the ultimate destination
is called a route. The GP-1610CF can automatically advance to the next waypoint on a
route, so you do not have to change the destination waypoint repeatedly.
You can store up to 20 routes. A route may
consist of 30 points.

GPS SPEED SMOOTHING: During position fixing, ship's velocity (speed and course)
is directly measured by receiving GPS satellite signals. The raw velocity data may change
randomly depending on receiving conditions
and other factors. You can reduce this random
variation by increasing the smoothing. Like
with latitude and longitude smoothing, the
higher the speed and course smoothing the
more smoothed the raw data. If the setting is
too high, however, the response to speed and
course change slows. "000" is the default setting; increase the setting if the GPS speed
changes greatly.
Figure 11-1 GPS setup menu
Speed(kt)
GPS SETUP menu description
GPS POSITION SMOOTHING: When the
DOP or receiving condition is unfavorable,
the GPS fix may change greatly, even if the
vessel is dead in water. This change can be
reduced by smoothing the raw GPS fixes. A
setting between 0 and 9 is available. The
higher the setting the more smoothed the raw
data. Note however that too high a setting
slows response time to change in latitude and
longitude. This is especially noticeable at high
ship's speeds. "000" is the default setting; increase the setting if the GPS fix changes
greatly.

chart system) can be directly selected. For
other charts, select OTHER and enter chart
number referring to Geodetic Chart List in the
Appendix. For sake of accuracy, the chart system selected here should be the same as that
of the cart card used. (See page 10-3.)
POS CALIB: You may apply an offset to
position generated by the internal GPS receiver, to further refine position accuracy. For
further details, see "10.2 Offsetting GPS Position."
11-1
UNHEALTH: Every GPS satellite is broadcasting abnormal satellite number(s) in the
Almanac. Using this information, the GPS
receiver eliminates any malfunctioning satellite from the GPS satellite schedule. Once the
malfunctioning satellite is returned to on-line
status it is automatically restored to the satellite schedule when the Almanac is received.
In some instances however the Almanac may
not contain information which announces that
a satellite is now back on line. If you hear of
this through another source, you can manually restore the satellite to the satellite schedule. Conversely, you can manually disable a
healthy satellite if you hear it is unhealthy.
To restore or disable a satellite, select RSTR
or DISABLED on the UNHEALTH line and
then enter satellite number.
TIME DIFF (using local time): GPS uses
UTC time. If you want to use local time, enter time difference between local time and
UTC time here. The
key serves to designate plus or minus time. See the World Time
Standards chart on page A-3 for time differences.
11.2 Speed Averaging
Calculation of ETA and TTG is based on an
average ship's speed over a given period. If
the period is too long and the ship's speed is
changed suddenly, calculation error will result. Speed averaging may be increased or
decreased to offset calculation error. The default setting is 00.

Glossary
GPS Plotter
Almanac
Each GPS satellite broadcasts its own orbital
data as well as general orbital data of all other
GPS satellites. This general orbital data is
called the Almanac. The GPS receiver receives
the Almanac and decodes it to calculate the
quantity and elevation angle of satellites in
view, to know when it can receive the GPS
signal. If there is no Almanac in the receiver
it cannot fix its position. The receiver is
shipped with no Almanac, thus when it is
turned on for the first time it starts receiving
the Almanac. Each time the unit is turned on
the previous Almanac is erased and the latest
received.
Beacon receiver
Differential GPS (DGPS)
The differential GPS system, consisting of
DGPS land stations and DPGS beacon receiver equipped marine vessels, further refines
the accuracy of the GPS measured position.
A DGPS land station knows its exact position. If there is a difference between GPS position and DGPS land stations position this is
called GPS error. The DPGS station transmits
GPS error data to a beacon receiver which
relays the data to the GPS receiver. The GPS
receiver uses this data to refine the accuracy
of the GPS position (within about 10 meters
under ideal conditions).
DGPS stations are strategically located
throughout America (including Hawaii and
Alaska), Europe, Canada, Bermuda and Brazil.
The DGPS (Differential GPS) station transmits a beacon signal which contains information about GPS error. The device which
receives the beacon signal is called a beacon
receiver.
Estimated time of arrival (ETA)
Cold start
A nautical chart is usually made by either
trigonometrical survey or astronomical survey and according to the geodetic chart standards of the country where it is used. The GPS
standard chart system is WGS-84.
When the GPS receiver is turned on for the
very first time, it starts receiving the Almanac. This condition is called cold start. In this
condition it takes about two minutes to find
position. Once the Almanac is stored in the
GPS navigator, it takes only about 20 seconds
to find position. (The normal start-up condition is called warm start.)
Destination
A destination can be either a single destination waypoint or a series of waypoints leading to the ultimate destination. When you set
a destination, the GPS receiver provides range
and bearing data to the destination, to help
you steer to the destination along the shortest
past possible.
The time at which you arrive at a destination.
Geodetic chart
Thus if you are using a chart different from
WGS-84, there will be error between GPS
position and nautical chart position. To get
correct position, the GPS receiver must know
what chart system you are using, to apply an
offset to GPS position.
Magnetic bearing
Bearing relative to magnetic north, with the
compass bearing corrected for deviation.
A-5
Magnetic variation offset
Time-to-go (TTG)
The location of the magnetic north pole is different from the geographical north pole. This
causes a difference between the true and magnetic north direction. This difference is called
magnetic variation, and varies with respect to
the observation point on the earth. This variation may be entered automatically or manually.
The amount of time necessary to get to a destination, maintaining current speed and course.
Navigation calculation
The GPS receiver calculates the range, bearing and cross- track error to next waypoint
when you select a destination. The calculation of that data is called navigation calculation.
Time differences
Time differences (or TDs) are the position
information generated by the Loran C and
Decca position-fixing systems. TDs are the
time in microseconds between the transmission of pulsed signals in the Loran C and
Decca systems.
Total distance
This is the number of miles from starting point
to end point in a route.
NMEA 0183
Trip distance
The National Marine Electronics Association's
signal format which enables connection of
electronic equipment of different marine electronics manufacturers.
The distance run from a position.
Plotting interval
The plotting interval determines both how the
track will be reconstructed on the display and
track storage time. The shorter the interval the
more accurate the reconstruction of track line,
however total storage time is reduced. The
plotting interval can be selected to time or
distance. Plotting by distance offers the advantage that the track is not stored when the
vessel is anchored.
S/A
GPS was developed by the US Department
of Defense mainly for use by its marine vessels and aircraft. For civil users the accuracy
of the system is purposely downgraded for
national security reasons. This intentional accuracy reduction is called S/A. Because GPS
position error may be greater than 100 meters
any GPS position should be double checked
against other sources to confirm position.
A-6
Trip elapsed time
The amount of time passed since departing a
starting point.
True bearing
Bearing relative to North; compass bearing
corrected for magnetic deviation. The GPS
receiver can display true or magnetic bearing.
Velocity to destination
The amount of speed in the direction (course)
of the desired destination.
Waypoint
A waypoint is a particular location on a voyage whether it be a starting, intermediate or
destination waypoint.
Video Sounder
Clutter
Cruising noise, polluted water or plankton can
clutter the screen with low signal level echoes. This situation can be improved by adjusting the CLUTTER function.
Detecting area
The detecting area varies with the main
beamwidth of the transducer. Objects out of
the main beam but close to the beam will be
presented less densely, smaller in size and at
a lower intensity.
Generally, beamwidth depends on Tx frequency; a narrower beamwidth is usually obtained at a higher frequency. The beamwidth
of the 200 kHz is narrow, thus it has the advantage of higher resolution. On the negative
side, fish at the sides of the boat can be overlooked because of the narrow beamwidth.
Gain
Gain adjusts the sensitivity of the receiver. It
should be set at the point where excessive
noise does not appear on the screen. Usually,
use a high gain setting for deep water; a low
one for shallow water.
Interference, noise
Interference can result from other acoustic
equipment which operates on the same frequency as your own or electrical equipment
on your boat which disturbs the video sounder.
In most cases interference can be suppressed
with the noise limiter.
Picture advance speed
Picture advance speed defines how fast the
video sounder picture moves across the display screen. Several speeds are available including freeze, which lets you stop
advancement to observe the picture more
closely.
Display color
Pulselength
A color video sounder displays an echo in a
color corresponding to its strength. The GP1610CF displays echoes in eight colors: reddish brown, red, orange, yellow, green,
light-blue, blue and black.
Frequency
The frequency of the ultrasonic pulse used in
video sounders is between 15 and 200 kHz,
and the GP-1610CF provides both 50 kHz and
200 kHz. The 200 kHz frequency offers a
sharp, clear-cut picture since its beamwidth
is narrow. However its use should be limited
to shallow waters since its pulse is easily attenuated in water. The 50 kHz frequency provides a longer sounding range since its pulse
it is not as easily attenuated.
Pulselength is the length of time the transmitter in the transducer is turned on each transmitted ultrasonic signal. Pulselength is linked
with range and thus cannot be selected. The
higher the range selected the longer the
pulselength.
Pulse repetition rate
The pulse repetition rate defines the number
of pulses transmitted within a certain period.
The more pulses transmitted the greater the
detection accuracy. The pulse repetition rate
is automatically changed with range.
Resolution
Resolution is the ability of the video sounder
transducer to discriminate returning signals.
The higher the transducer frequency the better the resolution.
A-7
Returning signal
Transducer
The ultrasonic pulse transmitted by the transducer "strikes" intervening objects such as the
bottom and fish schools and returns to the
transducer. The signal received at the transducer is called the returning signal.
A transducer converts an electrical signal into
an ultrasonic signal, transmits it in the water
and receives any returning signals from intervening objects. The higher the frequency of
the transducer the sharper its beamwidth.
Transducers are generally classified according to their method of installation. There are
three general classes: thru-hull, transom
mount or inside hull. The thru-hull type provides the best performance since the transducer protrudes from the hull and the effects
of air bubbles and turbulences are minimal.
Sounding range
Sounding range refers to the maximum depth
observable in the range in use. For example,
if the range selected is 0-100 meters, the maximum depth which you can observe is 100
meters. Of course, factors such as bottom composition and water conditions may affect the
sounding range.
Water temperature sensor
The water temperature sensor (option) measures water temperature near the transducer.
A combination water temperature and speed
sensor is also available.
