SIMRAD SH90
The catching machine
The Simrad SH90 is a perfect
catching machine. It is ideal for
mackerel, tuna, and all sh located
close to the bottom. With the Simrad
SH90, you can combine horizontal
and vertical beams, and you can view
the schools of sh with both a “bird’s
eye” and as a “slice” at the same
time. This provides vital school data
without passing over the target.
Full beam stabilization maintains
a clear picture of the target even in
rough seas.
The Simrad SH90, as with all
Simrad sonars, provides a dual mode
facility offering two sonars in one.
Individual tilt angle, range, gain and
lter settings can be made on each of
the two sonar presentations.
To create the Simrad SH90
sonar, the designers started from
scratch with a brand new design.
A new transducer was developed,
the transceiver technology has been
greatly improved, and the computing
power has been enhanced using a new
processor unit. The menu system is
however identical to the former SH80
and the highly appraised SX90. This
offers instant recognition, and makes
the sonar easy to use and understand.
Simrad high denition sonars detect weak and scattered targets
under difcult conditions
• New and improved FM
transmission
• Ideal for detection of mackerel,
tuna and all sh close to bottom.
• Detects weak and scattered
targets.
• Keep full control during
catching.
• Full 360° stabilization both in
transmission and reception.
• 90° vertical presentation
• High resolution in all ranges.
The Simrad SH90 has 0.35m
(14 inches) horizontal resolution
on all ranges. This gives good
separation of targets and is a
valuable feature for inspecting
schools, separating sh close to
bottom etc.
• The receiver’s wide dynamic
range will easily identify schools
with different densities, and
will also separate hard from soft
bottom.
• The sonar beam has a 7,5°
opening angle. This allows you
to detect sh close to the sea
surface or bottom.
• A new 180° vertical view,
which is tiltable down to 90°, is
specially designed for pelagic
trawlers.
• A new interface for a Kongsberg
MRU sensor has been
implemented. This option will
ensure extreme accurate beam
stabilization, and will also
improve detection of sh close
to the bottom.

SIMRAD SH90
Tuna
A 10 tons school of tuna has been
detected, and tracking has started.
The tracking functionality is vital for
the success of the catch. The SH90
allows you to track the school all the
way to the vessel without losing any
information. Then, when the seine is
set, the skipper has full control, and
he is able to maximize the catch. Note
the noise and clutter-free screen. This
enable the skipper to focus on the
targets, without acting as a “human
lter”. The SH90 provides detailed
information about school density,
speed, depth, heading and size.
The SH90 is the natural choice as a
companion to the SX90 low frequency
sonar.
Herring
In this screen capture a school
of herring has been detected, and it
is evaluated by the skipper. Target
tracking is activated, and in the lower
left corner the school’s heading,
distance from the vessel, and speed is
displayed.
The 180° vertical view is activated,
and can be seen in the lower part of
the screen.
The school is just lifting from the
bottom, and it has a good density.
This can be easily investigated due to
the extreme resolution found in the
Simrad SH90 sonar.
