To lessen risk of damage to the Sonar Head in case of
grounding, it may be mounted on the side of the vessel above
the keel line. If the keel obstructs the view to one side, the head
may be tilted to the opposite side. ”Ice knives” may also be
mounted in front of the head for protection against floating
debris.
In a dual head installation the two sonar heads may be placed on
each side of the keel and tilted about 30-40° above the
horizontal, thus increasing the swath width to both sides. 40° tilt
would be best for shallow waters and surveying to the water’s
edge while 30° would increase maximum depth capability
somewhat.
