About the Transducer
The transducer transmits and receives sound waves through the
water, and relays sound-wave information to your Garmin sonar
device.

À
, the transducer should
be mounted in front of and close to the engine or engines.
•
On inboard vessels
Á
, the transducer should be mounted in
front of and far away from the engine propeller and shaft.
•
On step-hull vessels
Â
, the transducer should be mounted in
