Transducer Setting

The Transducer Setting function enables
the user to optimise the operation of the
D100 for the particular transducer installed.
Transducer performance varies widely,
larger diameter transducers produce
strong signals resulting in improved deep
water performance but can suffer from
reduced shallow water performance, due
to transducer ringing. Smaller transducers
produce the opposite effect, with improved
shallow water performance and reduced
deep water performance.

There are three values of transducer
settings (1 to 3). The lower numbers
improve the shallow water performance
and may produce reliable readings to
below 3 feet. It is recommended to use the
lowest number possible if shallow water
performance is important. It must also be
noted that in situations where the D100 is
tracking the bottom and displaying a
consistent depth but occasionally
displaying -- or erroneous depths of 3 to 4
feet, that this generally indicates the
transducer setting is too low and should
be increased.

While in the Keel Offset mode, press the

 keys.

Use the

 and the 

V

 keys to set the

required value.

When the correct value is displayed, press
the
