FULL-CIRCLE COLOR SCANNING SONAR FSV-25/25S
Stunning performance, amazing range with FSV-25/25S!
With new 3D Sonar Visualizer™ F3D-S (optional application) you can see fish and sonar information in a 3 dimensions, "real world" view.
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.
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
