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.

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.
