Simrad launches new high frequency sonar

New Simrad SH90 sets new standards in
resolution
|
Simrad, one of the world’s most recognized brands within
professional fishing electronics launched the new SH90 high
frequency sonar at the World Fishing exhibition in Vigo, Spain,
16th – 19th September 2009. The SH90 is a tool to help improve
catch efficiency as its unrivalled resolution makes difficult
targets such as mackerel, tuna and fish close to the bottom far
easier to detect than before.
The high frequency SH90 is a complete redesign of the highly
regarded, de facto industry standard SH80 and includes new
transducer, transceiver and high-power processor, as well as
system signal processing software. Sophisticated features of the
SH90 include; linear FM transmission, horizontal and vertical
views; ‘Tip’ (tilting 180° fan shaped beam); 360° stabilization;
dual mode (two sonars in one); recording and a simple, intuitive
menu structure.
“In addition to improving on the popular SH80, the SH90 is based
on the same platform as the SX90, which has sold over 150 units
since its introduction in 2007, so we really have high
expectations for it,” says Mads Dahl, Sales & Marketing Director,
Simrad. “This is backed-up by positive feedback from two Norwegian
fishing vessels, the ‘Sjarmør’ and ‘Magnarson’ that have been
testing the SH90 during live fishing since the beginning of 2009
and more recently a successful trial aboard a Spanish tuna vessel.”
The brand new SH90 transducer is manufactured using high grade
ceramics, the most efficient material on the market today for this
purpose, using a technique pioneered by, and unique to Simrad
within the fishing industry. Each of the 480 elements are
precision tuned to the sonar’s operation frequency of 114 kHz.

In this screen capture a school of herring has
detected, and it now 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. |

The SH90 transceiver is completely redesigned with all boards
coated for protection from humidity and pollution and all
components the latest within ‘low power consumption technology’.
It is a completely sealed unit, which allows air to circulate
inside the transceiver. All of these design aspects were
implemented to ensure a longer lifetime for the electronics in the
harsh environments found onboard fishing vessels, therefore
provide even more value to customers.
“With the launch of the SH90, we are well positioned to
accommodate the growing new build market for offshore pelagic
fishery. These vessels, as well as all tuna vessels carry both a
high and a low frequency sonar and our goal is that a cost
effective SX/SH package will become the benchmark solution in the
industry for many years to come,” concludes Dahl. |
