Simrad SH90 Fish finding sonar

System description

The Simrad SH90 high definition sonar detects weak and scattered targets under difficult conditions.

The 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.

SIMRAD

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.

Key facts

  • New and improved FM transmission
  • Ideal for detection of mackerel, tuna and all fish close to bottom.
  • Detects weak and scattered targets.
  • Allows you to stay in full control during catching.
  • Full 360° stabilization both in transmission and reception.
  • 90° vertical presentation
  • High resolution in all ranges. The Simrad SH90 has 35 cm (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 can be tilted down to 90°, it is specially designed for pelagic trawlers.
  • A new interface for a Kongsberg motion reference unit sensor has been implemented. This option will ensure extreme accurate beam stabilization, and will also improve detection of fish close to the bottom.
