Important: Before proceeding, ensure that you have read and understood the warnings and
cautions provided in the

Location requirements

Follow the guidelines below when selecting a location for your single transducer or split-pair
transducers.
For best performance, transducers should be installed in a location with the least turbulence and
aeration.
Important: Do NOT install transducers in-line with trailer rollers, your vessel's engine intake or
discharge openings.
• Transducers should be installed as close to the center line of the vessel as possible.

• When installing split-pair transducers, the fairing block must be cut to the dead rise angle of the
hull, ensuring that the transducer elements point straight down.
• When fitting to a hull with a keel, ensure that the transducer beam will not be obstructed by the
keel. If the transducer cannot be fitted fore or aft of the keel then use split pair transducers to
overcome the obstruction.
