Beyond Depth. Into Intelligence.
Single Frequency Echosounder (Deep)
Built for autonomous bathymetry and real-time marine intelligence.
Engineered for Advanced Bathymetric Workflows
The Echologger Single Frequency Deep Echosounder series (ECT400 / ECS400) is a compact, survey-grade echosounder designed for advanced bathymetric surveying, hydrographic mapping, and underwater depth analysis. Built for autonomous platforms and challenging aquatic environments, it delivers reliable seabed profiling, accurate depth measurements, and full water column backscatter for high-integrity underwater data capture. With low-SWaP architecture, seamless system integration, and real-time acoustic performance, it supports efficient hydrographic workflows across USVs, ROVs, and AUVs in both shallow and extreme deep waters up to 6000m. Available in Acetal and Aluminium housing options, the series offers the perfect balance of compactness and durability. Smarter surveying. Deeper deployment. Reliable underwater intelligence.

Available in robust aluminium housing specifically engineered for deep water missions on ROVs, AUVs, and scientific underwater platforms requiring reliable long-duration survey performance at significant depths.
It enables stable underwater data acquisition, seabed mapping, and bathymetric applications from coastal waters to full-depth ocean missions.
SEACON Wet-Mate Underwater Connectivity
Integrated with professional-grade SEACON wet-mate connectors for secure underwater connectivity during deployment and recovery operations in deep water.
It ensures reliable power delivery and uninterrupted acoustic data transmission during demanding deep hydrographic and subsea survey missions.
Designed for long-duration operations where uninterrupted power and real-time data transmission are critical for high-pressure underwater survey performance.
Native Pixhawk & Ardupilot Compatibility
Supports native Pixhawk and Ardupilot integration through standard NMEA0183 altitude output for autonomous bathymetry, intelligent navigation, and real-time hydrographic workflows.
It delivers accurate terrain following, underwater obstacle awareness, and stable depth intelligence across USVs, ROVs, and autonomous survey platforms.
Reduces integration complexity and accelerates deployment within next-generation deep-water hydrographic and autonomous underwater systems.
Hydrographic Software Ecosystem Integration
Compatible with leading hydrographic surveying platforms, including Hypack, HydroMagic, HydroPro, and ReefMaster for streamlined underwater mapping and bathymetric data processing.
Supports efficient acquisition, visualisation, playback, and export of hydrographic datasets without requiring custom middleware or software adaptation.
Optimised for survey professionals managing high-efficiency deep-water hydrographic workflows, seabed analysis, and underwater terrain modelling operations, the software delivers top-notch performance.
Real-Time Echogram Visualization Interface
Powered by an intuitive survey control interface designed for live underwater monitoring and operational control during hydrographic missions.
Features real-time echogram visualisation, acoustic profiling, playback functionality, adjustable ping configuration, gain control, and survey data logging in a clean operator-focused environment.
Also, simplifies underwater survey management for both first-time users and advanced hydrographic teams, improving mission efficiency and data visibility in deep water operations.
Integrated Tilt & Environmental Intelligence
Supports optional dual-axis roll and pitch sensing combined with high-resolution temperature monitoring for improved underwater positioning awareness and acoustic measurement stability.
Tilt compensation helps maintain accurate seabed profiling when operating in dynamic water conditions or moving autonomous platforms.
Environmental sensing data enhances bathymetric accuracy, sound velocity interpretation, and underwater survey consistency in complex deep-water operational environments.
