INSIDE THE HULL MOUNTED TRANSDUCER
Installation Guide
2
| Trial Installation
You will not be able to adjust the mounting position after you install this transducer inside the hull.
In order to determine the best mounting area (before permanently mounting the transducer), it is
best to perform a trial installation first that includes running the boat at various speeds.
1. Connect the transducer cable connector to the control head.
2. Power on the control head. When the control head detects a functioning transducer, it will
start Normal mode automatically. Select a sonar view to display on-screen.
3. 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 mounted inside the hull.
4. Place the transducer body face down at the identified mounting location inside the hull,
oriented as shown in the illustrations (see Transducers with Directional Bias and Transducers
without Directional Bias).
5. Fill the hull with enough water to submerge the transducer body. Use a sand-filled bag or
other heavy object to hold the transducer in position.
NOTE: The transducer cannot transmit through air, so the water is necessary to purge any
air from between the transducer and the hull, and to fill any voids in the coarse fiberglass
surface of the hull.
6. View the sonar signal on the control head display and compare it against what you observed
in step 3, making sure that the boat is in the same location as it was during your observations
in step 3. If the results are comparable, continue to step 7. Otherwise, locate a new position in
the hull and repeat steps 4 through 6.
7. Run the boat at various speeds and water depths while observing the screen on the control
head. If depth performance is required, test the transducer in water at the desired depth. If the
performance is acceptable, continue to step 8. If the performance is not acceptable, repeat
steps 4 through 7.
8. Once you have determined the best mounting location using this procedure, mark the position
of the transducer.
9. Power off the control head. Unplug the transducer cable connector from the control head.
