SIMRAD SH90

Simrad high denition sonars detect weak and scattered targets
under difcult conditions

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.

(I) Transducer

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.

• 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.

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.
