360-DEGREE OMNI SCANNING SONAR Model FSV-85 MARK-2

Features

• Horizontal modes

  The horizontal display mode provides a 360 degree picture around the vessel. The H2 mode shows one of four kinds of horizontal display combinations: PORTRAIT,LANDSCAPE, RIGHT INSET and LEFT INSET. The range, tilt, gain and user program are set independently, for each display.

  

  

  

• Slant mode

  The slant mode provides a half-circle (180 degrees) picture like half-circle Sonar.

  

  

• Horizontal and Vertical Display Combinations

  The world's first sonar in its class to combine two vertical sections. The sonar is capable of recording a vertical cross-section (0-90°) in any direction, either in one direction or in two directions. This allows the user to compare two schools of fish at the same time.

  

  

• High resolution for long range detection

  The combination of highly sensitive sensors and Furuno's new processing technology allows for longer range detection than ever before
  while maintaining high resolution targets.

• Target lock function for fish tracking (requires vessel speed and heading data)

  Automatically track schools of fish while calculating their speed and direction. Also display the distance and depth from the vessel to the school.
  It is also possible to track a fixed position such as a sea current.

  

  By hitting the target lock mark on a fish school echo, the distance and depth to that school of fish, as well as the direction and speed of movement are displayed numerically.

• Fish concentration and histogram display to help you decide when to cast your net

  In conjunction with the target lock function, the sonar can display the relative volume of fish in the estimate mark. This helps you to make the right decision when casting your net.

  

  Up to two fish quantity marks can be typed on one screen, and the response of each is displayed as a histogram. This is useful for determining the amount of fish.

• Auto filter for clearer images

  The FSV-85-MARK-2 incorporates a digital filter that regulates noise interference, providing a clear view of the display at high speed without affecting the Sonar.

• Stabilization function

  The beam stabilization function compensates for the effects of pitch and roll. This allows stable detection of sea currents and schools of fish, even in poor weather conditions.

  

• Storage and playback of Sonar images

  The FSV-85-MARK-2 allows you to take a screenshot and playback Sonar images.

  

  The recording will be played on a pop-up screen.

• User-Friendly, Programmable, Intelligent Controls

  The User Program Control (up to 10 programs) provides for instant setup of the equipment according to fishing ground or target fish. Ten programs may be set up, and vertical and horizontal display settings may be programmed together or individually. In addition, 10 function keys provide one-touch display of desired menu or frequently used menu settings such as: Recording still images, recalling still images, erasing marks, activitate or deactivate the beam stabilization etc.

  

  

  Customizable menu

• Short raise/lower time of the transducer & intuitive position indicator

  The greatly reduced raise/lower time of the transducer allows for quick adjustment to prevent damage to the transducer.

  Travel	Time (seconds)
  800 mm	8
  1100 mm	11

  
  The position indicator lets you know the position of the transducer at a glance.

• Marine grade monitors MU series displays

  With its bright colors, excellent contrast and wide viewing angles, Furuno MU series displays are perfect for any tropical sunlight or low light conditions.
  A dual display configuration allows the user to display information on two monitors simultaneously. This is very useful for viewing information quickly on each of the two monitors and for comparing them. The display brightness can be changed simply by rotating the knob on FSV-85 MK2 control unit.
