• 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 MARK-2 among one of the fastest hull units available. You can extend and retract the transducer rapidly for smooth operation.

• Extended detection range to identify schools of fish at great distances

  Thanks to recent advancements in low-frequency transducer elements, signal processing and increased transmission power, the detection range has been greatly improved (by about 30%) with the FSV-25 and FSV-25 MARK-2 series. You can instantly spot and follow schools of fish from several kilometers away.

• Automatic target lock function for easy tracking of fast-swimming fish

  FSV-25 MARK-2 will automatically lock onto schools of fish, and display estimates of distance, depth, speed and angle of movement. Target lock is also available for stationary positions (speed and heading information required).

  

• 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 safety at sea.

  

• Beam stabilization function for unwavering performance

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

• Wired Remote and Sub Control Unit available

  
  Remote controller (wired)
  Model: FSV-854-MK2

• Stop function when extending and retracting transducer

  In order to avoid collisions with drift wood and other material, the transducer can be lowered to the desired position.

• Echo strength distribution histogram

• Auto filter for clear and uninterrupted performance

• 3D Sonar Visualizer™ F3D-S (Optional Application)

  3D Sonar Visualizer™ F3D-S is a new product that works in conjunction with the FSV-25 MARK-2 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.

Screenshots

• 
  (3000 m range) A school of fish 2000 m ahead. The fish school appears to swim close to a reef.
• 
  (300 m range) Two schools of fish can be seen right after the purse-line has been pulled and the net has been closed.
• 
  (5000 m range) A school of bait fish can be seen on the port side of the vessel.
• 
  (1000 m range) Targeted school of fish 650 meters away.
• 
  (150 m range) Schools of tuna and skipjack tuna spotted.
• 
  (400 m range) Individual bigeye tuna can be seen in this fish school.
• 
  (800 m range) A school of fish close to the seabed can be distinguished clearly.
