Simrad SY50

Compact fish-finding omnidirectional sonar for coastal fisheries

The Simrad SY50 is an compact omnidirectional medium frequency fish-finding sonar designed for coastal fisheries. It is mainly designed for smaller fishing vessels and offers the latest technology available, previously found only on larger sonars and other acoustic systems.

The compact design allows for easy installation

The compact size and ease of installation make the Simrad SY50 ideal for vessels with limited room for a sonar installation. There is no transceiver cabinet, only a small power supply. All the transceiver electronics are contained inside the transducer, resulting in fewer cables, less noise, and a more straightforward setup. The communication between the hull unit and the computer on the bridge is limited to a single Ethernet cable. Moreover, the hull unit and the computer may also operate on DC power, which is perfect for coastal fishing vessels without a 3-phase power system.

Advanced sonar capabilities

The Simrad SY50 uses 256 individual receiver- and transmitter channels to offer a clear and high-resolution sonar presentation. This functionality is unparalleled in a sonar in this price range. This includes full beam stabilisation, vertical views, FM transmission, and single-ping transmission that covers horizontal and vertical in one ping. The popular 'Winson' operating software, with a familiar user interface in almost 20 languages, makes the Simrad SY50 incredibly user-friendly.

Efficient and customisable operation

The cylindrical multi-element transducer of the Simrad SY50 allows for omnidirectional sonar beams to be tilted electronically from +10 to -60° in 1° steps, facilitating automatic tracking of fish schools. Built-in stabilisation is available for electronic pitch and roll compensation with external sensor connectivity for enhanced accuracy. You can also define and save your specific settings for efficient operation. At the same time, the optional small operating panel simplifies basic operating features, communicating with the computer through a single USB cable.

QuadPing™

The groundbreaking commercial- and sportfishing tool we have named QuadPing™ is now available to you. QuadPing is an advanced sonar functionality that simultaneously uses four transmissions ("pings") to find and track the fish from deep in the water to your vessel. We have implemented this functionality as a dedicated presentation mode on your sonar system. The QuadPing™ functionality is a free upgrade for all our users, making your sonar one of the few systems with such advanced features.

QuadPing is a significant step forward in sonar technology. It provides you with a real advantage. QuadPing sends out four "pings" simultaneously in dual, split-screen mode. The echoes from the first ping are shown in the first view as a reference. The echoes from the other three pings, each with a different tilt angle, are displayed in the second view. The first view detects the fish, while the second maps and tracks the catch to your boat. The sonar's full omni-stabilization of transmission and reception beams enables this functionality. This functionality is particularly beneficial for purse seiners and sports fishing.

Key features are:

  • Two horizontal views: one single swath of echoes in the left view and three swaths combined into one view on the right-hand side.
  • The three combined pings are separated by 10 degrees tilt. The tilt of the middle ping is shown.
  • The frequency is shown for the second swath. The other two are ±1 kHz of the second swath.

"Winson" operating software

This sonar uses the latest "Winson" operating software. This unique software platform is common for all Simrad sonars. It allows you to present the various sonar echoes in separate views, which you can move to separate display monitors. Another great feature of the new software is its ability to "ping" all the beams simultaneously. Multiple pings increase the ping rate and thus offer a more frequent update of the sonar echoes in the views.

Other standard features of the "Winson" operating software are:

  • User interface in more than 20 languages
  • Intuitive access to all operating parameters
  • Save and recall your favourite user settings
  • Save and replay sonar images and video sequences
  • Target and position tracking

Sonar operating panel

This sonar supports the optional Operating Panel Mk.2. This operating panel uses a handy multifunction joystick. The joystick facilitates tilt, vertical, and inspection beam control through simple pushes or twists of the knob. The operating panel communicates with the Processor Unit using an Ethernet connection. This communication format allows for advanced functionality. You can manage up to four different Simrad sonars using a single panel. Conversely, up to three panels in various locations on the vessel can operate a single sonar. The USB port on the operating panel also provides convenient software upgrades and user settings management. The operating panel also features dedicated and customizable buttons and knobs, and its design allows for a straightforward upgrade from older panels using a mounting bracket.

Seamless communication with other vessel sensors

The sonar system provides several standard interface lines. These interfaces ensure seamless communication with peripheral devices and sensors, with typical inputs like geographical information, vessel speed, and heading. The built-in motion sensor enhances operational accuracy, and you can increase this accuracy by adding an external motion reference unit (MRU).
