FULL-CIRCLE COLOR SCANNING SONAR Model FSV-25/25S

Features

• Maximum detection range increased by 30%

  Thanks to recent advancements in low-frequency transducer elements, signal processing and increased transmission power, detection range has been increased by a full 30%*. You can instantly spot and follow schools of fish from several kilometers away.
  *Compared with FSV-24/35. Performance may vary depending on depth, range and signal frequency used.
  
  
   

• Improved resolution with new signal compression algorithms

  　
  Left image: (150 m range) Schools of tuna and skipjack tuna spotted.
  Right image: (400 m range) Individual bigeye tunas can be seen in this school of fish.

• Graphical hull-unit indicator

  See exactly how much the transducer is lowered directly on your display with a simple graphical interface. Instantly spot if and how much the transducer is lowered or retracted, helping you avoid accidents and increase the safety at sea.
  

• Fully extend the transducer in just 12 seconds for 1200 mm stroke and in 16 seconds for 1600 mm stroke

  A transducer “throw” time of just 12/16 seconds (respectively) places the FSV-25 among one of the fastest hull units available. You can extend and retract the transducer rapidly for smooth operation.

• Stop function when extending and retracting transducer

  In order to avoid collisions with drift wood and other material, the transducer can be stopped while in motion. The transducer can be lowered to any given length until full extension.

• Stabilization function for unwavering performance

  The stabilizer ensures that echoes are stable when received, regardless of transducer attitude, counteracting the rolling and pitching motions at sea.

• Automatically track schools of fish with target lock function

  FSV-25 will automatically lock on schools of fish found and display estimates of distance, depth, speed and angle of movement. Target lock is also available for stationary positions (speed and heading information required).

• Auto filter for clear and uninterrupted performance

  The auto filter ensures that you get clear and crisp echoes even when travelling at speed. The auto filter is also highly effective against interference from other fishfinder equipped vessels.

• Accurate control with large physical control unit

  

• Wired Remote and Sub Control Unit available

• 3D Sonar Visualizer™ F3D-S (optional application)

  3D Sonar Visualizer™F3D-S is a new product that works in conjunction with the FSV-25/FSV-25S to show fish and sonar information in 3 dimensions. It uses the hull unit of your existing sonar but then processes the information in a unique way to show fish, peaks and sea floor data in a 3 dimensional "real world" view. Clearly see the size and shape of midwater marks to assess the best way to fish them and, with careful adjustment of the simple depth line control delete the seabed echoes to visualize fish schools close to the seabed.
