Summary and general recommendations
Some of the installation guidelines provided for transducer location may be conflicting. For
this reason, each vessel must be treated individually in order to find the best compromise.
In general, the most important factor is to avoid air bubbles in front of the transducer face.
For this reason, the recommended transducer location is normally in the fore part of the hull,
well ahead of the noise created by the bow wave.
The maximum distance from the bow is normally equal to one third of the total water line
length of the hull.
Note
Mounting the transducer more than 10–15 meters from the bow may cause problems with
the turbulent flow.
