INSTRUCTIONS
Important Safety Information
WARNING
See the
Important Safety and Product Information
guide in the product box for product warnings and other
important information.
Failure to follow these warnings, cautions, and notices could result in personal injury, damage to the vessel or
device, or poor product performance.
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
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
To avoid possible personal injury or damage to the device and vessel, disconnect the vessel's power supply
before beginning to install the device.
To avoid possible personal injury or damage to the device or vessel, before applying power to the device, make
sure that it has been properly grounded, following the instructions in the guide.
To avoid possible personal injury or damage to this device and vessel, only install this device when the vessel is
on land, or when properly secured and docked in calm water conditions.
For the best possible performance and to avoid potential injury, damage to the device, or damage to your vessel,
installation by a qualified marine installer is recommended.
NOTICE
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
Read all installation instructions before proceeding with the installation. If you experience difficulty during the
installation, contact Garmin Support.
Transducers
A transducer is required to send and receive a sonar signal from the sonar module. Proper transducer selection
and installation are critical to the operation of the device. Because mounting locations vary, see your local
Garmin dealer or contact Garmin Support for more information. Go to
garmin.com/transducers
to select a
transducer.

Because every boat is different, you must carefully plan the GSD 28 sonar module installation.
1
Select a mounting location.
2
Mount the sonar module.
3
Connect the sonar module to the transducer.
4
Connect the sonar module to power.
