Echologger's ECT D24, ECS D24, ECT D710, and ECS D710 models mark a significant advancement in professional echosounding technology, now equipped with the remarkable capability to be deployed at depths of up to 6000m. This groundbreaking feature enhances their utility in a variety of underwater applications, providing professionals with unparalleled flexibility and reliability even in the most challenging environments.

The ECT D24 and ECS D24 models stand out as compact and lightweight precision echosounders, featuring universal serial interface schemes RS232 and 485. Their deployability at depths of up to 6000m makes them ideal choices for underwater surveys and inspections, ensuring precise data collection in diverse scenarios.

On the other hand, the ECT D710 and ECS D710 models take underwater data collection to new heights with their high-frequency support (750kHz/1MHz) and the capability to withstand depths of up to 6000m. Designed for extreme precision, these models find applications in sediment move studies, bathymetric surveys, and various manned and unmanned operations.

This new feature of deployability at up to 6000m depth significantly expands the scope of applications for these echosounders. Whether deployed on Remotely Operated Vehicles (ROVs) or Autonomous Underwater Vehicle (AUVs)U or in manned operations, the ECT D24, ECS D24, ECT D710, and ECS D710 models stand as resilient tools capable of delivering precise underwater data in challenging conditions.
