Down Imaging™ Sonar
(Down Imaging
™
models only
[596c HD DI, XNT 9-DI-T Transducer])
Your
596c HD DI Fishfinder
uses Down
Imaging™
technology.
The
Down
Imaging™ transducer scans the water with
razor-thin, high-definition beams. The
beams are wide (side to side) but very thin
front to back.
The Down Imaging™ beams can be
operated at two frequencies: 455 kHz (75°)
or 800 kHz (45°). Select 455 kHz for the
best overall image quality and depth.
Select 800 kHz for the sharpest image. See
Down Imaging
™
X-Press
™
Menu:
Imaging Frequency
for more information.
The transducer also uses conical beams to
provide data in traditional 2D format (see
What’s on the Sonar View
). Select 455 kHz for
a narrowly focused 16° center beam, or select
200 kHz for a wider 25° beam (see
Sonar
Menu Tab: Beam Select
).
Depth capability is affected by such factors
as boat speed, wave action, bottom hardness,
water conditions and transducer installation.
