1 Introduction

The SPEED 3100 measures and displays boat speed
and water temperature. It can calculate and display
average speed, maximum speed, trim speed, trip log
(distance) and total log.

An installed SPEED 3100 usually has two parts:

The display unit.
A speed / temperature transducer which is

attached to the hull and wired to the display unit.
The unit is powered from the boat’s power supply.
The SPEED 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 7).

For maximum benefit, please read this manual
carefully before installation and use.

The SPEED 3100 display unit

Display

(backlit)

How the transducer measures speed

The speed transducer has a small paddlewheel
which spins as the boat moves through the water.
The transducer measures how fast the paddlewheel
is spinning and calculates the boat speed by
averaging several measurements.

Cleaning and maintenance

Clean the display unit and the plastic transducer with
a damp cloth or mild detergent. Avoid abrasive
cleaners, petrol or other solvents.

When repainting the hull, cover or remove any visible
transducer. Do not use a high pressure water blast
on the speed transducer paddlewheel as it may
damage the bearings.

SPEED 3100 log Installation and Operation Manual

3 Speed, average speed, maximum speed, trim speed

The unit can display several speeds:

SPEED: The current boat speed.
AVG SPEED: The average speed since AVG

SPEED was reset or the unit was switched on.
MAX SPEED: The maximum speed since MAX

SPEED was reset or the unit was switched on.
TRIM SPEED: Trim speed may be used for

tuning racing boats. Trim speed measures
changes in boat speed, relative to when you
reset trim speed to zero. For example, if the
boat is travelling at 10 knots and you reset trim
speed, then trim speed is zero. Then:

If the boat speed increases to 11.5 knots,
the trim speed is 1.5 knots.

If the boat speed decreases to 8.5 knots,
the trim speed is -1.5 knots.

3-1 Set speed and log units

The speed units can be selected to be KNOTS, KPH
and MPH. Selecting one of these automatically sets
the log distance units to NM, KM or M (miles):

Press or until SPEED is displayed, then
hold until the units change; if necessary,
hold again until the units change again.

3-2 Reset average speed

Resetting starts calculating a new average speed:

3-4 Reset trim speed

Resetting sets the trim speed to zero:
1 Press
2 Press

until TRIM SPEED is displayed.

+ .

3-5 Set speed damping

Waves and wind cause the boat speed to fluctuate
slightly. To give a stable reading, the SPEED 3100
calculates the boat speed and trim speed by
measuring the speed several times and averaging
the measurements. The speed damping value
ranges from 1 to 5:

A lower value averages readings over a shorter
period of time. This gives the most accurate
speed but has the most fluctuations.

A higher value averages readings over a longer
period of time. This gives the most stable speed
but will ignore some true speed changes.

Set the speed damping to the lowest value which
gives a stable speed reading. Values of 1, 2, 3, 4
and 5 average readings over a time period of 6, 12,
18, 24 and 30 seconds respectively. To get the most
accurate, stable trim speeds, you may need to
increase the damping. To set speed damping:

3-7 Calibrate speed

Calibration may be required, because different hull
shapes have different water flow characteristics.
Speed calibration can be done either by the speed
or by the log, as described below. If speed readings
are taken from a GPS receiver (see section 7), then
you can not calibrate it.

Calibrate by speed

In this method, travel at a measured, constant speed.
Use the speed displayed on a GPS receiver, follow
another boat travelling at a known speed or make a
timed run over a known distance.

Note that for accurate calibration:

The speed from a GPS receiver should be
above 5 knots.

The speed from another paddlewheel
transducer should be between 5 and 20 knots.

Best results are achieved in calm conditions
where there is minimal current (best at high or
low tide).

Continue travelling at this measured, constant speed
and calibrate the speed as follows:

Measured
speed

1 Press + several times until the Speed

Calibration screen is displayed (after this, it

Calibrate by log

In this method, travel a known distance in a straight
line over a course. Best results are achieved in calm
conditions where there is minimal current (best at
high or low tide). Tidal effects may be reduced by
making the trip twice, parallel to the current, once in
each direction:

1 At the start of the course, reset the trip log (see

7 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.

7-1 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 9-2, step 3). 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.

If an alarm sounds, mute it by pressing on
any instrument which can display that alarm.

NavBus and the SPEED 3100

If the SPEED 3100 does not have a speed/
temperature transducer fitted then the unit will
automatically take speed and temperature
readings from another instrument, via NavBus, if

the data is available. For more information, refer
to the NavBus Installation and Operation Manual.

If the boat has a GPS instrument connected to
the instruments via NavBus then you can set up
the SPEED 3100 to use this for speed readings
instead of a speed transducer (see section 9-1
for wiring and section 9-2, step 2 for setup).

Note: The speed from a paddlewheel sensor
is the speed that the boat is moving through
the water. A speed from a GPS is the speed
over the ground. If there is a current then
these two speeds will be different.

If a transducer is not fitted to the unit and the
corresponding external data is not available then
the displayed value will be 0 (for example, when
using a GPS input for speed and no speed/
temperature transducer is fitted to any instrument
on the NavBus then temperature displays as 0).

7-2 NMEA

NMEA is an industry standard, but is not as flexible
as NavBus as it requires dedicated connections
between instruments. Speed, temperature and log
data are output by the SPEED 3100 and can be read
and displayed by the NAVMAN REPEAT 3100 or
other NMEA instrument. The SPEED 3100 can also
receive GPS speed data (NMEA RMC) from any
compatible NMEA GPS instrument - GPS speed
must be selected (see section 9-2, step 2).

Warranty card.
Mounting template.
This Installation and Operation manual.

In addition, the standalone configuration usually
requires a speed/temperature transducer (see
section 8-3).

Kit configuration

The SPEED 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 speed/temperature transducer
Transducer Installation manual.

8-2 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
SPEED 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 7 or the NavBus
Installation and Operation manual).

8-3 Transducers

The SPEED 3100 is usually used with a through hull
speed/temperature transducer. However , the unit can
take readings from another instrument, in which case
it may not need a transducer (see section 7).

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 wood
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, for more information, refer to the
Transducer Installation manual or consult your
NAVMAN dealer .

9 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 SPEED 3100 can:

Drive external beepers or lights for the
countdown timer.

Send and receive data from other NAVMAN
instruments connected via NavBus. Settings
for alarms, units, calibration and backlighting
are shared (see section 7-1).

Send and receive NMEA data from other
instruments (see section 7-2).

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.
