Echologger proudly presents the EU D24, a groundbreaking USB-interfaced professional echosounder, distinguished as the sole device in the market supporting dual frequencies (200kHz/450kHz). This cutting-edge feature empowers professionals in underwater surveys, offering the flexibility to select between two distinct frequencies, making the EU D24 an invaluable tool for applications like professional bathymetric surveys and scour monitoring.

For scenarios involving extremely shallow waters, the EU D710 takes center stage with its exceptional support for high frequencies (750kHz/1MHz). This model is meticulously designed to excel in shallow environments, providing precise data collection in conditions where accuracy is paramount. The EU D710 finds its application in various operations, including sediment move studies, making it a reliable choice for professionals working in both manned and unmanned operations.

Complementing these advancements, the sister models ECT D24, ECS D24, ECT D710, and ECS D710 further contribute to Echologger's diverse echosounder portfolio. These models, featuring the universal serial interface schemes RS232 and 485, enhance compatibility with various systems. This broadens their utility across different applications, from manned operations like bathymetric surveys to unmanned operations on vehicles such as drones or remotely operated vehicles (ROVs).
