Echologger proudly introduces the EU D032 / ECT D032 and EU D052 / ECT D052, ultracompact Dual Frequency Echosounders designed to elevate underwater surveys with a unique combination of low frequency (30kHz or 50kHz) and conventional 200kHz capabilities. This innovative fusion of frequencies enhances the reliability of echosounder data, particularly benefiting sediment studies. By employing both low and conventional frequencies, these echosounders provide a comprehensive understanding of underwater environments, extracting valuable information from sub-bottom layers.

The EU D032 / ECT D032 and EU D052 / ECT D052 models offer a flexible range of interface schemes, including USB and serial interfaces (RS232 or RS485). This diversity ensures seamless integration with various systems, allowing users to tailor the echosounders to their specific requirements. The choice of interface schemes underscores Echologger's commitment to providing adaptable solutions that align with the unique needs of customers in diverse underwater survey scenarios.

Widely adapted by professional bathymetric survey firms equipped with Unmanned Surface Vehicles (USVs) and drones (UAVs), these ultracompact Dual Frequency Echosounders redefine the possibilities for sediment studies. The incorporation of low frequencies not only enhances reliability but also allows for the extraction of extra information from sub-bottom layers, providing professionals with a more comprehensive dataset for their analyses.
