1. Determine the transducer mounting location
Decide where to install the transducer on the inside of the hull. Consider the
following to find the best location:
• Observe the outside of the boat hull to find the areas that are mostly
free from turbulent water. Avoid ribs, strakes and other protrusions,
as these create turbulence.
• As a general rule, the faster the boat can travel, the further aft and
closer to the centerline of the hull the transducer has to be located
in order to remain in contact with the water at high speeds.
2. Trial installation
You will not be able to adjust the mounting after an inside the hull
transducer is installed. It is best, therefore, to perform a trial installation first
that includes running the boat at various speeds, in order to determine the
best mounting area before permanently mounting the transducer.
1. Plug the transducer into the control head, then power up the control
head. When the control head detects a functioning transducer, it
will automatically enter Normal operating mode.
2. View the sonar signal at its best by holding the transducer over the
side, immersed in the water, so that it is pointing straight down over a
known flat bottom. Use the display to benchmark against the sonar
signal that will be detected once the transducer is placed in the hull.
3. Place the transducer body face down at the identified mounting
location inside the hull, with the end that has the mounting ears
pointed towards the bow of the boat.
