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.
