The BASIC 2D sonar is a low-cost, ultracompact, multi-purpose sonar. It contains a logarithmic amplifier which combines high-sensitivity and high-dynamic range and a high performance processor with DSP. It is the lowest cost model in the SONAR 2D line. 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.
