INSTALLATION INSTRUCTIONS
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the product box for product warnings and other
important information.
The device must be installed with at least one of the included anti-rotation bolts. Failure to do so could result in
the device rotating while the boat is moving and could cause damage to your vessel.
You are responsible for the safe and prudent operation of your vessel. Sonar is a tool that enhances your
awareness of the water beneath your boat. It does not relieve you of the responsibility of observing the water
around your boat as you navigate.
CAUTION
Failure to install and maintain this equipment in accordance with these instructions could result in damage or
injury.
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
To obtain the best performance and to avoid damage to your boat, you must install the Garmin
®
transducer
according to these instructions.
Read all installation instructions before proceeding with the installation. If you experience difficulty during the
installation, contact Garmin Product Support.
Software Update
You must update the Garmin chartplotter software when you install this device. For instructions on updating the
software, see your chartplotter owner's manual at support.garmin.com.

Mounting Considerations
•
On outboard and sterndrive vessels , you should mount in front of and close to the engine or engines.
• On inboard vessels , you should mount the transducer in front of and far away from the engine propeller
and shaft.
• On step-hull vessels , you should mount the transducer in front of the first step.
• On full-keel vessels , you should mount the transducer at a slight angle that aims at the bow, not parallel to
the centerline.
• On fin-keel vessels , you should mount the transducer from 25cm to 75cm (from 10to 30in.) in front of
the keel and a maximum of 10cm (4in.) to the side of the centerline.
• On vessels with displacement hulls , you should mount the transducer approximately
1
/
3
aft of the
waterline length of the vessel from the bow, and from 150 to 300mm (from 6 to 12in.) to the side of the
centerline.
• You should mount the transducer in a location where it will not be jarred when launching, hauling, or storing.
• You should mount the transducer in a location where it is not behind strakes, struts, fittings, water intake or
discharge ports, thru-hull transducers, or anything that creates air bubbles or causes the water to become
turbulent. Turbulent water may interfere with the sonar beam.
• You should mount the transducer in a location where there are no bulkheads or stringers on the interior of the
boat that impede a clear surface for the fairing block.
• You should mount the transducer as close to the center line of the boat as possible.
2
•
When mounted farther from the center of the transom, a greater deadrise can cause the boat hull to
interfere with the sonar beam , and can cause inconsistent detection on the opposite side of the boat .
These illustrations show the transducer from behind.
• On single-drive vessels, you must not mount the transducer in the path of the propeller.
• On twin-drive vessels, you should mount the transducer between the drives, if possible.
• You must install the sonar module in a location with adequate ventilation, where it will not be exposed to
extreme temperatures.
• You should mount the sonar module in a location where the LEDs are visible.
• You should mount the sonar module in a location where the cables can be easily connected.
Fairing Block Angle Cut
A fairing block positions your transducer parallel to the water line for increased sonar accuracy. You must
measure the deadrise angle of your boat hull to determine if a fairing block is necessary to mount the
transducer. If the deadrise angle of your mounting location exceeds 5°, you should use a fairing block to mount
the transducer.
Deadrise Angle
Deadrise is the angle formed between a horizontal line and a boat hull at a single point. You can measure the
deadrise angle with a smartphone application, an angle finder, a protractor, or a digital level. You can also ask
your boat manufacturer for the deadrise angle of the specific point on your boat hull.
NOTE: A boat may have several deadrise angles depending on the shape of the hull. Measure the deadrise angle
only at the location where you plan to install the transducer.
3
Cutting the Fairing Block
CAUTION
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
1 Using wood screws, attach the fairing block to a piece of wood.
The wood becomes a cutting guide for the fairing block.
2 Measure the deadrise angle of the hull at the mounting location.
3 Tilt your table saw blade to match the deadrise angle and secure the cutting fence.
4 Position the fairing block on the table so the cutting guide rests against the fence and the angle matches
the angle of the mounting location.
5 Adjust the cutting fence to ensure the fairing block has a minimum thickness of 2mm (
1
/
16
in.).
NOTE: The maximum cutting angle of the fairing block is 25°.
6 Cut the fairing block.
7 Using a rasp or power tool, shape the fairing block to the hull as precisely as possible.
8 Use the remaining section of the fairing block as the backing block inside the hull.

Mounting the GLS
™
10 Black Box Device
NOTICE
If you are mounting the device in fiberglass, when drilling the pilot holes, use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
NOTE: Screws are included with the device, but they may not be suitable for the mounting surface.
Before you mount the device, you must select a mounting location, and determine what screws and other
mounting hardware are needed for the surface.
1 Place the black box device in the mounting location, and mark the location of the pilot holes.
2 Drill a pilot hole for one corner of the device.
3 Loosely fasten the device to the mounting surface with one corner, and examine the other three pilot-hole
marks.
4 Mark new pilot-hole locations if necessary, and remove the device from the mounting surface.
5 Drill the remaining pilot holes.
6 Secure the device to the mounting location.
Blink Codes
After the sonar module is installed, it turns on when the chartplotter is turned on. The color status LED on the
sonar module indicates its operational status.

Maintenance
Testing the Installation
NOTICE
You should check your boat for leaks before you leave it in the water for an extended period of time.
Because water is necessary to carry the sonar signal, the transducer must be in the water to work properly. You
cannot get a depth or distance reading when out of the water. When you place your boat in the water, check for
leaks around any screw holes that were added below the water line.
Anti-Fouling Paint
To prevent corrosion of metal and to slow the growth of organisms that can affect a vessel's performance, you
should apply a water-based anti-fouling paint to the transducer every six months.
NOTE: Never apply ketone-based anti-fouling paint to your vessel, because ketones attack many types of plastic
and could damage or destroy your transducer.
Cleaning the Transducer
Aquatic fouling accumulates quickly and can reduce your device's performance.
1 Remove the fouling with a soft cloth and mild detergent.
2 If the fouling is severe, use a scouring pad or putty knife to remove growth.
3 Wipe the device dry.
