Important
It is the owner’s sole responsibility to install and use the instrument in a manner that will not cause accidents, personal injury or property damage. The user of this product is solely responsible for observing
safe boating practices.
Global Positioning System: The Global Positioning System (GPS) is operated by the US Government
which is solely responsible for its operation, accuracy and maintenance. The GPS system is subject to
changes which could aff ect the accuracy and per formance of all GPS equipment anywhere in the world
including the Explorer 660. Whilst the Northstar Explorer 660 is a precision navigation instrument, it can
be misused or misinterpreted, which can result in its use being unsafe. To reduce the risk of misusing
or misinterpreting the Explorer 660, the user must read and understand all aspects of this Installation
and Operation manual. We also suggest that the user practice all operations using the built in simulator
before using the Explorer 660 at sea.
Electronic Chart: The electronic chart used by the Explorer 660 is an aid to navigation and is designed
to supplement the use of offi cial government charts not replace them. Only offi cial government
charts supplemented by notices to mariners contain the information required for safe and prudent
navigation. Always supplement the information provided by the Explorer 660 with other plotting sources
such as observations, depth soundings, radar and hand compass bearings. Should the information not
agree then the discrepancy must be resolved before proceeding any further.
Sonar fishfinder: The accuracy of the sonar depth display can be limited by many factors,
including the type of the transducers, the location of the transducers and water conditions. It is the user’s
responsibility to ensure the Explorer 660 transducers are installed and used correctly.
Fuel Computer: Fuel economy can alter drastically depending on the boat loading and sea conditions.
The fuel computer should not be the sole source of information concerning available fuel onboard and
the electronic information should be supplemented by visual or other checks of the fuel load. This is
necessary due to possible operator induced errors such as forgetting to reset the fuel used when fi lling
the tank, running the engine with the fuel computer not switched on or other operator controlled actions that may render the device inaccurate. Always ensure that adequate fuel is carried onboard for the
intended trip plus a reserve to allow for unforeseen circumstances.
Failure to adhere to these warnings may lead to death, serious injury or property damage.
Northstar disclaims all liability for installation or use of this product that causes or contributes
to death, injury or property damage or that violates any law.
As Northstar is continuously improving this product we retain the right to make changes to the product at
any time which may not be refl ected in this version of the manual. Please contact your nearest Northstar
offi ce if you require any further assistance.
The Explorer 660 is set up with default units of feet, °F (Fahrenheit), US gallons and knots.

Northstar Explorer 660 Installation and Operation Manual6
1 Introduction
The Northstar Explorer 660 is a compact, rugged,
highly integrated GPS navigation chartplotter
and sonar fishfinder. It is designed to be easy to
use and has a large, easy to read color display.
Complex navigation or fishfinding functions can
be performed with a few key presses, taking the
hard work out of boating.
This manual describes how to install and operate
the Explorer 660 and gives troubleshooting and
operating tips.
GPS Navigation
The Explorer 660 has a built-in chart of the world,
suitable for route planning and general interest.
To see chart details for a region, plug in a C-MAP™
chart card (an electronic chart).
The Explorer 660 receives GPS position
information from an external GPS antenna and
displays the boat’s position and speed.
The Explorer 660 can navigate to a point or
can navigate along a route. When the boat is
navigating to one of these points, the Explorer
660 displays course information for the
helmsman to follow. The Explorer 660 can control
an autopilot.
Sonar fishfinding
The Explorer 660 has a 50 kHz / 200 kHz dual
frequenc y sonar transducer and a 600 W RMS
power output to ensure that the Explorer 660
operates ef fectively in shallow and deep water.
The Explorer 660 can detect the bottom to a
depth of 3300 feet (1000 metres) depending on
the clarit y of the water, the ultrasonic frequency
chosen and the t ype of transducer used.
The Explorer 660 can be used to find fish, to
locate features on the bottom such as reefs or
wrecks and to help recognize favorite fishing
spots from the bottom profile.
The Explorer 660 uses Northstar’s proprietary SBN
technology for sonar processing. Digital adaptive
filter algorithms enhance all returned signals and
filter false returns. Active noise control rejects
interference, which can often be mistaken by
fishfinders for true returns.
Other fun ctions
With an optional fuel kit, the Explorer 660
becomes a sophisticated yet easy to use fuel
computer. Navigation data can be saved to
a plug-in user card so that it can be easily
transferred to another Northstar char tplotter.
The Explorer 660 is par t of the Northstar family
of instruments, which includes instruments
for speed, depth, wind and repeaters. These
instruments can be connected together to form
an integrated data system (see section 16-6).
For maximum benefit, please read this manual
carefully before installing and using the unit.
Special terms are explained in Appendix C.
1-1 Cleaning a nd maintenance
The Explorer 660 screen is covered by a
proprietary anti-reflection coating. To avoid
damage, clean the screen only with a damp cloth
and mild detergent when dirty or covered in
sea salt. Avoid abrasive cleaners, petrol or other
solvents. If a plug-in card gets dirt y or wet, clean
it with a damp cloth or mild detergent.
Cover or remove a transom-mounted transducer
when repainting the hull. If painting over a
through hull transducer with antifouling paint,
use only one coat of paint. Remove
coat of antifouling paint by sanding it lightly.

Northstar Explorer 660 Installation and Operation Manual 7
To optimize per forman ce, avoid w alking o n
or jamming cables and connectors. Keep the
transducer free of weed, paint and debris. Do not
use a high pressure water blast on a speed sensor
paddlewheel as it may damage the bearings.
Push the dust cover over the display when the
Explorer 660 is turned off.
1-2 Plug-in cards
The Explorer 660 can use two kinds of plug-in
card:
C-MAP™ chart cards have chart details
required for navigating in a particular region.
When a chart card is plugged in, the extra
details automatically appear on the Explorer
660 chart display.
C-MAP™ user cards are used to store
navigation data. Each user card expands the
Explorer 660 memor y and allows the data to
be transferred to another Explorer 660 easily
(see section 13).
Note: The older 5 volt user cards are not
suppor ted.
Changing the p lug-in card
The Explorer 660 has two card slots and can use
two plug-in cards at the same time. It does not
matter which slot a card is inserted in.
CAUTION
Handle plug-in cards carefully. Keep them in
their protective cases when not plugged into
the Explorer 660.
Keep the holders in place in the E xplorer 660
at all times to prevent moisture from entering
the card compartment.

3-1 Introduction to navigating
The Explorer 660 has t wo ways of navigating,
going straight to a point or following a route.
Enter waypoints at points of interest before
starting to navigate (see section 5-2-1).
Tip: Create a waypoint at the star t of the trip
to navigate back to.
Goto: Going st raight to a point
The Explorer 660 can navigate straight to a
waypoint or to any arbitrar y point:
1 Switch to the chart display
(see section 2-6).
2 Start navigating using the GOTO/AUTO key
(see section 3-4).
When the Explorer 660 is navigating, the

navigation data. The chart shows:
The boat position .
The destination point marked with
a circle.
The boat’s plotted course to the
destination.
Two CDI lines, parallel to the boat’s
plotted course (see Appendix C, CDI).
If the Explorer 660 is connected to an
autopilot, the Explorer 660 will send data
to the autopilot to steer the boat to the
destination. Start the autopilot.
If the XTE alarm is enabled, an alarm will
sound if the boat deviates too much from its
intended course (to set the XTE alarm, see
section 15-8).
3 If the arrival radius alarm is enabled, then,
when the boat comes within the arrival
radius of the destination, an alarm will sound
to show that the boat has reached the
destination (to set the arrival radius alarm, see
section 15-8).
4 To stop the Goto, see section 3-4.
Following a route
A route is a list of waypoints that the boat can
follow (see section 6).

route, see section 5-2-1.
2 To create a route, see sec tion 6-2-1.
3 To start the route, see sec tions 3-4 or 6-3-1.
When the Explorer 660 is navigating,the
chart, data and highway displays show
navigation data. The chart shows:
The boat position .
The waypoint at the end of the current
leg marked with a circle.
The boat ’s plotted course along the leg.
Two CDI lines, parallel to the boat’s
plotted course (see Appendix C, CDI).
If the Explorer 660 is connected to an
autopilot, the Explorer 660 will send data
to the autopilot to steer the boat to the
destination. Start the autopilot.
If the XTE alarm is enabled, an alarm will
sound if the boat deviates too much from its
intended course (see section 15-8).
If the arrival radius alarm is enabled, then,
when the boat comes within the arrival radius
of the waypoint at the end of the current leg,
an alarm will sound (to set the arrival radius
alarm, see section 15-8).
4 The Explorer 660 stops navigating to the
waypoint at the end of the current leg and
starts the next leg of the route:
a When the boat comes within 0.025 nm of
the waypoint.
b Or when the boat passes the waypoint.
c Or if the waypoint is skipped (see section
