- Sonar
Stabilizer function never misses targeted fish
school in stormy seas
- Higher output and longer pulse
- Stainless steel dome transducer
- Quick variable beam angle
- Easy to use keyboard
- SXGA pixel resolution (1280 x 1024)
Features
Enhanced fish tracking performance by the stabilizer function
The high-precision stabilizer function installed in this compact sonar ensures tracking of a target fish school even in rough seas.
Stable beams keeping targets on track
Beams unstable due to ship motions
Newly designed transducer with significantly expanded detection range
High beam output and long pulse by increasing the size (1.4 times of its predecessor)
- Stainless steel dome transducer with a strong anti-corrosion feature, contributing to a reduction of maintenance cost
- Safety design that automatically stores the transducer when the vessel speed exceeds the specified level
- Hoisting unit designed to shut down the power immediately at abnormality
Enhanced visibility by the narrow-angle beams
Quick beam angle change function to detect fish schools easily Narrow angle beams provide a sign of a weak reflection of a fish school as well as improved visibility of schools of shoal fish and rock fish.
Optimum mode selection according to the operation condition
The JFS-280 provides high-definition images covering 32 color video output with a sharp 19-inch high resolution LCD (1280 x 1024 pixels). The JFS-280 clearly displays the distribution and density of a fish school. You can select the most suitable mode according to your operation condition.
