Important Safety Information
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.

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.
Failure to install and maintain this equipment in accordance with these
instructions could result in damage or injury.
Always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
When drilling or cutting, always check what is on the opposite side of the
surface.
This equipment should be installed by a qualified marine installer.
To obtain the best performance and to avoid damage to your boat, you must

About the Transducer
The transducer transmits and receives sound waves through the water, and
relays sound-wave information to your Garmin sonar device.
Mounting Location Considerations
• On outboard and sterndrive vessels
in front of and close to the engine or engines.
• On inboard vessels , the transducer should be mounted in front of and
far away from the engine propeller and shaft.
• On step-hull vessels , the transducer should be mounted in front of the
first step.
• On full-keel vessels , the transducer should be mounted at a slight angle
that aims at the bow, not parallel to the centerline.
• On fin-keel vessels , the transducer should be mounted from 25 cm to
75 cm (from 10 to 30 in.) in front of the keel and a maximum of 10 cm
(4 in.) to the side of the centerline.
• On vessels with displacement hulls
1
approximately / aft of the waterline length of the vessel from the bow, and
3
from 150 to 300 mm (from 6 to 12 in.) to the side of the centerline.
• The transducer should be mounted parallel to the bow-stern axis of your
vessel.
• The transducer should not be mounted behind strakes, struts, fittings,
water intake or discharge ports, or anything that creates air bubbles or
causes the water to become turbulent.
The transducer must be in clean (non-turbulent) water for optimal
performance.
• The transducer should not be mounted in a location where it might be
jarred when launching, hauling, or storing.
• On single-drive boats, the transducer must not be mounted in the path of
the propeller.
The transducer can cause cavitation that can degrade the performance of
the boat and damage the propeller.
