VOYAGER
DEPTH
INSTALLATION
AND
OPERATING
INSTRUCTIONS
Please
read
this
booklet
thoroughly
before
installing
and
operating
this
equipment
.
INTRODUCTION
The
VoyagerDepth
Sounder
is
a
microprocessor
controlled
instrument
which
operates
by
measuring
the
time
interval
between
transmission
and
reception
of ultrasonic
pulses
from
the
seabed
via
a
piezo
electric
transducer
fitted in
the
hull
of
the
boat
.
Depth
information
is
displayed
on
a large,
custom
made,
liquid
crystal
display
in
both analogue
and
digital
form,
thus
combining
the
accuracy
of
digital
information
with
the
more
easily
assimilated
trend
indications
of
analogue
device
.
Designed
with ease
of
operation
in
mind,
there
is
no
requirement
for the
user
to
adjust
gain,
range
or
output
power
of
the
Voyager
Depth
instrument
.
The
sensitivity
of
the
receiver
and
the
RMS
output
power
are
precisely
controlled
by
the
microprocessor
so
that
the
instrument
will
always
operate
at
its
optimum
setting
for
all
possible
combinations
of
depth
and
seabed
conditions
.
This, together
with
the
ability
to
discriminate
between
true
and
false
ethos,
provides
a
steady
and
accurate
reading
of
depth,
which
is
not
effected
by
external
interference
.
Additional
facilities
which
are
provided
include
depth
readings
in digital
form
up
to
300 metres
(975
feet)
under
optimum
conditions
.
Analogue
depth
information
up
to
100
units
(metres
or
feet,
user
selected)
.
The
Logarithmic
scale
provides
expanded
discrimination
in
shallow
water
.
Audible
and
visual
deep
and
shallow
alarms
adjustable
from0
.75

.
Keel
Offset
enabling
zero
setting
to
waterline
or
boat
draught
up
to
10
m
.
Built
in
display
illumination
for
night
time
use
.
The
instrument
has
been
designed
for
permanent
installation
in
a
bulkhead
or
dashboard and once
correctly
installed
.
i
s
completely weatherproof
.
Adjustments
to Calibration,
Alarms
and Keel
Offset
can
be
made
using
the
five
key
tactile
keyboard
.
As
an
option,
a
swivel
mount
is
available
but
this
method
of
mounting
is
only
recommended
for
dry
cabin
installations
.
INSTALLATION
Transducer
Installation
(Through
Hull)
WARNING
:
The
co-axial
cable
is
sealed
into
the
stem
of
the
transducer
and
if
damaged
in
any
way
cannot be
reconnected
.
The
transducer
lead
has
a
nominal
length
of
22
.3
ft
(6
.8
m)
and
should not
be
extended
or
cut
without
the
advice
of a
service
engineer
.
Any
excess
cable
should
be
coiled
away
from
excessive heat
or
sources
of
electrical
interference
.
Transducers
with
longer
cable
can
be
supplied
to
special
order
.
For
full
depth
performance
the
transducer
stem
should
be
mounted
as near
vertical
as possible
.
Install
the
transducer
in a
part of
the
hull
which
is
as
clear
as
possible
from
aerated
or
turbulent
water and
where
accidental
damage
is
unlikely
to
occur
.
Normally
a
position
slightly
aft
of
amidships
is
preferable
.
For
fin-keel
sailing
boats
it
may
be
preferable
to
fully
recess the
transducer
into
the
stem
so that
the
face
is
completely
flush
.
It
should
be
remembered
that
the
beam
angle
of
the
transducer
is
±22'/2
°and
care
should
be
taken
that
a
false
echo
is
not
created
by
the
keel
.
If a
single
transducer
is
installed
on
the
centre
line
of
the
boat
depth
readings
will
be
obtained
up
to
an
heel
angle
of
22'/2°
.
If
two
transducers
are
required,
to
avoid
fin-keels for instance,
then
each
should
be
fitted
in
opposite
bilges facing
outward
at
an
angle
of
approximately
15°
.
By
using
an
automatic
changeover
switch
(optional
extra)
available
from
all
good
chandlers,
a
twin
transducer
installation
will
enable
the
Voyager
Depth
to
give
accurate
depth
readings
to
an
heel
angle
of 37
1/2 °
.
The
following
illustration
indicates
typical
transducer
installations
using
a
wooden
fairing
block
outside
the
hull
.
The
fairing
block
has
been
carefully
bored, carved
and sanded
to a
streamlined
shape
avoiding
the
creating
of
turbulent
water
which
may
reduce
or
even
prevent
depth
indication
when
the
boat
is
travelling
at a
speed
.
In
one of
the
examples
shown,
an
internal
fairing
block
has
been used
for
strength
and
sealing
and
to
allow
for
hull
curvature
.
The
installation
should
be
carefully
rendered
watertight
by
using
a
sealing
compound
between
all
mating
surfaces
.
Do
not
over-tighten
the
nuts
on
the
transducer
stem
.

with
one
thin
coat of
hard
Antifouling,
carefully

.
Care
should
be
taken
not
to
damage
the

that
it
protects
.
Accidental
damage
to
this

cannot
be
repaired
.
TRANSDUCER
INSTALLATION
IN
HULL
(GRP)
As
an
alternative
to
mounting
the
transducer
through
the
hull
with
the
face
in
direct
contact
with
the
water,
it
may
be
positioned
inside
a
glass-fibre
hull
by
means
of
an
In
Hull
Transducer
Kit
as
shown
in
Fig
.
2
.
The
In Hull
Transducer
Kit
is
available
from most
Chandlers
and
Boatyards,
as
an
optional
extra
.
The end
cap
of
the
In Hull
Transducer
Kit
is
provided
with
a
push-out
insert
making
it
suitable
for
the
stem
diameter
of
the
Voyager
Depth
transducer
.
This
method
of
installation
has
the
dual
advantage
that
no
hole
is
made
in
the
vessel's
hull
and
that
the
echo
sounder
and
transducer
can
easily
be
removed
for
examination
or
installation
elsewhere
.
It
should
be
mentioned
however,
that
although
the
accuracy
will
in
no
way
be
affected
by
installing
the
transducer
inside the
hull,
the
maximum
range
sensitivity
may
be
reduced
depending upon
the
thickness
and
quality
of
the
glass-fibre
.
We
do
not
recommend
this
method
of
installation
if
the
thickness
of
the
glass-fibre
exceeds
three
quarters
of an
inch
.
Neither
do
we
recommend
its
use
in
hulls
of
wood,
steel
or
aluminium
although
this
method
of
installation
has
been
found
acceptable
with
these
materials
in
some
cases
.
Full
installation
details
are
supplied
with
the
In
Hull
Transducer
Kit
and
copies
are available
on
request
to
Seafarer
Navigation
International
Limited
.
Main
Instrument
Installation
When
selecting
a
suitable
location
for the
display
unit,
it
should
be
noted
that
the
contrast
of
the
LCD
display
is
greatest
when
viewed
at
eye
level
or
slightly
below
eye
level
.
If
the
display
is
viewed above
eye
level,
then
some
loss
of
contrast
will
be
experienced
.
A
compass
safe distance of
approximately
two
feet
shuld
also
be
observed
.
Having
selected
a
suitable
location, the
mounting
holes
can be
cut,
following
the
template
supplied
with
this
book
.
Voyager
Depth
will
operate
only
from
the
ship's
12
volt
DC
supply
and
it
is
recommended
that
an
on/off
switch,
capable
of
supplying
5
amps
at
50
volts,
is
connected
in
series
with
the
positive
supply
line
between
the
unit
and
the
boat
supply
.
This
will
allow
the
depth
sounder
to
be
operated
independently
of
other
boat
equipment
.
Next,
complete
all
other
interconnections
as
detailed
in
Figure
3
.
The
display
unit
is
supplied
complete
with
an
O
ring
sealing
gasket but
is
should
be
noted
that this
will
only
be
fully
effective
if
the
mounting
surface
is
perfectly
flat
.
If
this
is
not the
case,
then
a
suitable
sealant
should be
used
between
surfaces
before
tightening
the
nurled nuts
.
Audible
Alarm
Module
This
unit
can
be
located
in
any
sheltered
position
and
the
leads
extended by
using
a
terminal
block
and
additional
cable
as
required
.

Voyager
display
is
now
in
"Keel
Offset"
mode,
with
the
display
showing
cal,
zero
segment,
and 0
.0
feet
.
This
indicates
that
no
value
of keel
offset
has
been
-
entered and under
these
conditions,
all
depth
measurements
will
be
taken
from
the
transducer
to
the
seabed
.
NOTE
-
Whenever
the
Voyager
instrument
is
switched
off,
then
on
again,
it
will
always
first
return
to
the
"Keel
Offset"
mode
in
its
zero
setting
and
any
previous
entry
of
Keel
Offset
will
be
cancelled
.
Purpose
of
Keel
Offset
(See
Figure
4)
This
facility
enables
zero
depth
on
the
display
to
be
set at
waterline
or,
to
the
bottom
of
the
vessels
keel
.
Thus,
for
example,
if
the
transducer
is
mounted
2
.5
feet
below
waterline
and
a
(T)
keel
offset
of
2
.5
feet
is
entered, then
the
true
depth
between
waterline
and
seabed
will
be
displayed
.
Conversely,
if
a (-)
keel
offset
of
-2
.5
feet
is
entered,
then
depth
displayed
will
be
from
bottom
of
vessels
keel to
seabed

will
increase
in
a
clockwise
direction
.
This
will
continue
until
the vessel
moves
into
water
which
is
deeper
than
the
