SIMRAD SH90

The catching machineThe Simrad SH90 is a perfect

catching machine. It is ideal for mackerel, tuna, and all fish located close to the bottom. With the Simrad SH90, you can combine horizontal and vertical beams, and you can view the schools of fish 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 filter 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 definition sonars detect weak and scattered targets under difficult conditions

• New and improved FM transmission

• Ideal for detection of mackerel, tuna and all fish 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 fish 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 fish 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 fish close to the bottom.

TunaA 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 filter”. 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.

HerringIn 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.
