Features

Detailed echoes near the seabed thanks to enhanced detection capabilities

A higher resolution allows us to clearly separate the echoes from the fish and the seabed

The adoption of innovative signal processing technology dramatically increases the sensitivity of the Sonar and provides clearer and sharper echoes.

High frequency (180 kHz) allows clear and easy discernment between fish and seabed, or fishing net and school of fish

The FSV-75 uses high frequency (180 kHz) which can easily detect fish tight on the bottom or nets. This allows you to locate and track fish on the screen with greater accuracy.

Perfect to search for fish with rapid movement such as skipjack or tuna

The FSV-75 is particularly useful for fast moving fish such as tuna and skipjack, thanks to a fast transmitting/receiving rate at short range.

Fan-shaped beam, higher scanning speed, wider range, the performance of half-circle Sonar taken to a whole new level

Detect fish that you might otherwise overlook thanks to the combination of 3 technical improvements, such as a unique fan-shaped beam, a greater detection range, and a higher scanning speed.

The underwater in 3D!

3D MODE INTRODUCTION VIDEO

This mode allows you to monitor the location and movement of fish relative to the seabed in 3D, which makes fish detection and net casting operation more efficient.

Forward detection history mode

The forward detection history mode scans the forward area of own ship, and shows sonar echoes in 3D format. This mode is useful for estimating the profile of the sea bed.

Tilt cross-section mode*

The tilt cross-section mode scans the tilt angle within the selected width, and shows the underwater Sonar echoes in the scanning area in 3D format. This mode useful for seeing the shape of the fishing net in the water.

3D display

Sweep cross-section mode*

The sweep cross-section mode rotates the detection beam in a sweep (revolution) direction with the tilt angle fixed to "90 degrees", and shows the underwater Sonar echoes around own ship in 3D format. This mode is useful for finding the position of a school of fish.

Other functions available with the 3D mode

[Density calculation function ]

The function displays a virtual "basket" measuring the approximate volume of fish in the selected area. The amount of fish expected in the measurement zone is displayed in the "density information window". Knowing in real time the fish volume in the target area allows the fisherman to determine the best time to start fishing operation.

[Cross-sectionnal slice function]

The cross-sectional function allows you to see echoes of the cross-section of a 3D model sliced in a vertical and horizontal plane.

On screen "Retract Transducer" indicator for quick adjustment and damage prevention.

In the presence of close marine objects, which could potentially damage the transducer, it is useful to know the degree of retraction for quick adjutsment when necessary.
By pressing mid protrusion key on the display, it allows the transducer to be only half-retracted.

Instantly spot if and how much the transducer is lowered or retracted, helping you prevent damage to the transducer.

Quick and secure operation!

Thanks to a control panel specially designed for Half-circle sonars, all operations allowing fish search and tracking, such as adjusting the sonar rotation parameters or tilting, can be performed simply and efficiently. This control panel comes with 10 of the most popular function keys among the current FSV series sonars, and it is possible to register your favorite functions from 40 available functions. A convenient one-click delete button is also included.

Tank guide for a robust Hull Unit.

Thanks to a "Tank Guide" mechanism, the transducer is protected from vibrations and impact, which considerably improves the stability and durability of the sonar.

Shorter lowering/retracting time.

The transducer can be deployed and retracted in 11 seconds (1100 mm), it's half the time of current Sonar models.
