Important: Before proceeding, ensure that you
have read and understood the warnings and
cautions provided in the Chapter 1 Important
information section of this document.
3.7 Selecting a location for the
transducer
This product is supplied with a transom mount
transducer. The guidelines below should be followed
when selecting a location for the transducer.
Note: The transducer is not suitable for mounting
on vessels where the transom is aft of the
propeller(s).
For best performance the transducer must be
installed in a location with the least turbulence and
aeration. The most effective way to determine this
is by checking the water flow around the transom
whilst underway.
• The transducer should be mounted close to
the keel (centreline) of the vessel, so that the
transducer remains fully submerged when the
vessel is turning.
• The transducer must be mounted a suitable
distance from the propeller(s) to avoid wake.
• For clockwise rotating propellers the transducer
should be mounted on the starboard side, for
anti-clockwise rotating propellers the transducer
should be mounted on the port side.
• On a twin engine vessel the transducer should be
mounted between the engines.
• Turbulence can also be caused by a number of
other factors such as steps, ribs, strakes, and
rows of rivets. The turbulence appears aft of these
locations.
