This manual represents the DEPTH 3100 as at the time of printing. Navman NZ Limited reserves the
right to make changes to specifications without notice.
Governing Language: This statement, any instruction manuals, user guides and other information relating

(Translation). In the event of any conflict between any Translation of the Documentation, the English
language version of the Documentation will be the official version of the Documentation.
The DEPTH 3100 measures and displays the depth
of the water. An installed DEPTH 3100 usually has
two parts:
The display unit.
A depth transducer, which is attached to the
hull and wired to the display unit.
The unit is powered from the boat’s power supply.
The DEPTH 3100 is part of the NAVMAN family of
instruments for boats, which includes instruments
for speed, depth, wind and repeaters. These
instruments can be connected together to form an
integrated data system for a boat (see section 4).
For maximum benefit, please read this manual
carefully before installation and use.
How the transducer measures depth
The depth transducer generates an ultrasonic
The DEPTH 3100 display unit
(sound) pulse, which travels down through the water.
When the pulse meets the bottom, some of the pulse
is reflected back up towards the boat and is received
by the transducer.
The display unit analyses the reflections from each
pulse. It removes unwanted reflections (from bubbles
and other objects) and calculates the depth by
measuring the time between sending the pulse and
receiving its echo.
Cleaning and maintenance
Clean the display unit and any plastic transducers
with a damp cloth or mild detergent. Avoid abrasive
cleaners, petrol or other solvents.
When repainting the hull, cover or remove any visible
transducers. Depth transducers may be coated with
a thin layer of antifouling paint; gently sand off any
previous paint first.

Depth and keel offset
The displayed depth is the distance from the
transducer on the boat to the bottom of the water,
plus or minus an offset which is called the keel offset:
A positive keel of fset displays depth as
measured from a point above the transducer.
For example, if you set the offset to the
distance from the transducer to the surface, it
will display the depth from the surface to the
bottom of the water.

4 Systems of several instruments
Several NAVMAN instruments can be connected
together to share data. There are two ways of
connecting instruments together, NavBus or NMEA.
4-1 NavBus
NavBus is a NAVMAN proprietary system that allows
systems of multiple instruments to be built using a
single set of transducers. When instruments are
connected by NavBus:
If you change the units, alarms or calibration in
one instrument, then the values will
automatically change in all other instruments
of the same type
Each instrument can be assigned to a group of
instruments (see section 6-2, step 2). If you
change the backlight in an instrument in group
1, 2, 3 or 4 then the backlight will automatically
change in the other instruments in the same
group. If you change the backlight in an
instrument in group 0 then no other
instruments are affected.
Keel offset
(negative)
If an alarm sounds, mute it by pressing on
any instrument which can display that alarm.
NavBus and the DEPTH 3100
If the DEPTH 3100 does not have a depth transducer
fitted then the unit will automatically take depth
readings from another instrument, via NavBus, if the
data is available. For more information, refer to the
NavBus Installation and Operation manual.
Note: If a transducer is not fitted to the unit and the
corresponding external data is not available then the
displayed value will be dashes (— —).
4-2 NMEA
NMEA is an industry standard, but is not as flexible
as NavBus as it requires dedicated connections
between instruments. Depth data is output by the
DEPTH 3100 and can be read and displayed by the
NAVMAN REPEA T 3100 or other NMEA instrument.

5-1 What comes with your DEPTH 3100
The DEPTH 3100 comes in several configurations.
Standalone configuration
DEPTH 3100 unit with protective cover.
Warranty card.
Mounting template.
This Installation and Operation manual.
In addition, the standalone configuration usually
requires a depth transducer (see section 5-3).
Kit configuration
The DEPTH 3100 is available in several kit
configurations with different grades of through hull
transducer, with:
The parts for the standalone configuration,
listed above.
Through hull depth transducer.
Transducer Installation manual.
5-2 Other parts required
One or more 3100 series instruments will be
connected to the boat 12 V power supply via:
An accessory switch to turn the instruments on
and off.
A fuse. Use a 1 A fuse for between one and five
instruments.
Optional external beepers or lights can be fitted. The
DEPTH 3100 output is switched to ground, 30 V DC
and 250 mA maximum. If the beepers and lights
require more than 250 mA, fit a relay.
For systems of several instruments, wiring and
connectors are required (see section 4 or the NavBus
Installation and Operation manual).
5-3 Transducer
The DEPTH 3100 is usually used with a through hull
depth transducer. However , the unit can take readings
from another instrument, in which case it may not
need a transducer (see section 4).
A through hull transducer generally gives the best
performance and is the best choice for displacement
hulls. It is mounted in a hole drilled through the bottom
of the boat.
A plastic through hull transducer is suitable for
GRP or metal hulls. Plastic through hull
transducers are not suitable for solid wooden
hulls (use NAVMAN’ s bronze transducers).
A bronze transducer is suitable for wood or
fibreglass hulls. Never install a bronze
transducer in a metal hull, because it will
cause electrolytic corrosion.
A range of NAVMAN through hull transducers are
available, plus in hull and transom mount
transducers. For more information, refer to the
Transducer Installation manual or consult your
NAVMAN dealer .

6 Installation and setup
Correct installation is critical to the performance of
the unit. It is vital to read this section of the manual
and the documentation that comes with the other
parts before starting installation.
The DEPTH 3100 can:
Drive external beepers or lights for the alarm.
Send and receive data from other NAVMAN
instruments connected via NavBus. Settings
for alarms, units, calibration and backlighting
are shared (see section 4-1).
Send and receive NMEA data from other
instruments (see section 4-2).
Warnings
The unit is waterproof from the front. Protect the rear
of the unit from water, or else water might enter the
breathing hole and damage the unit. The warranty
does not cover damage caused by moisture or water
entering the back of the unit.
Ensure that any holes that you cut will not weaken
the boat’s structure. If in doubt, consult a qualified
boat builder.
The choice, location, angle and installation of
the transducers is the most critical part of the
installation. If they are not correct, the unit can
not perform at its designed potential. If in
doubt, consult your NAVMAN dealer. Plastic
through hull transducers are usually unsuitable
for wood hulls. If in doubt, consult a marine
surveyor or marine engineer.
6-1 Installation
