Sonar 2D-Enhanced

Latest Firmware


The SONAR 2D-ENHANCED is a low-cost, ultracompact, high-performance, multi-purpose sonar. It contains a logarithmic amplifier which combines high-sensitivity and high-dynamic range, a highperformance processor with DSP, and MEMS inertial sensors. A distinctive feature of this model is increased emission power with the ability to adjust the frequency over a wide range as well as a built-in IMU. Its complete solid-state design within a stainless-steel case makes it a durable and unpretentious operational device for industrial applications.

It’s easy to get started with a simple UART interface and open source examples. Its binary protocol provides for maximum performance and data integrity checking. Updating the firmware is simple, providing the most current features or even individualized solutions according to customer needs. Built-in non-volatile flash memory saves its settings even when not connected to power or a host.
