Mounting the transducer | HDS Gen3 Installation Manual
Mounting the transducer
Transducer location selection and installation are two of the
most critical steps in sonar installation. To function properly the
transducer must be in the water at all times, and in a location that
has a smooth fl ow of water while the boat is moving.
Research
Before starting the installation of the transducer, it’s advised to
check the following:
• Find out if the boat builder has a recommended installation location
• Establish direction of rotation of the propeller(s)
• Watch actual water fl ow when boat is travelling at cruising speed to
determine the area of transom with the cleanest fl ow (least bubbles)
Select a transducer location
The primary aim is to stay clear of propeller and hull generated
turbulence, while mounting the transducer as close to the center of
the vessel as possible.

1 Avoid mounting within 1 m (3.3’) to port (left) of propeller
2 Conventional clockwise propeller rotation
3 Avoid mounting within 7.5 cm (3“) to starboard of propeller
4 Best mounting location - undisturbed water fl ow
5 Planing strake - avoid mounting behind here

Note: Reverse the distance guides (1 & 3) from propeller where
engine is of counterclockwise confi guration.
