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)

High performance sonar capable of detecting any type of fish


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.

  • 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.
