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.
D 12640-1
• On a twin engine vessel the transducer should be mounted
between the engines.
D 12641-1
• 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.
