The Echo Sounder HE-771 represents an evolution in Honda’s sonar technology, combining high precision with operational simplicity.
The Echo Sounder HE-771 represents an evolution in Honda’s sonar technology, combining high precision with operational simplicity. Unlike traditional analog systems, the HE-771 utilizes a digital processing engine capable of sharply separating fish targets from background noise. This allows users to visualize complex seabed structures and distinguish individual fish species even when they are positioned near the bottom.
HONDA ELECTRONICS has brought innovations to the world by introducing ultrasonic technologies since the release of the world-first transistor fishfinder in 1956. With originality in mind, HONDA ELECTRONICS also respects technologies in various fields and participates in many collaborative projects. This “Open Technology” policy shall lead us to make further contributions that will enhance human life.
