Dual-frequency echo sounder D60

compactsingle-beam

Overview
The CHCNAV D60 is an integrated dual-frequency single-beam echosounder engineered for bathymetric depth measurement from USVs and manned vessels. Operating at 200 kHz and 33 kHz, it combines high-frequency accuracy with low-frequency penetration for reliable surveys across shallow and deep waters. The compact design simplifies installation on constrained platforms.

Main features

• Ultra-compact form factor for seamless USV integration and portability.
• Integrated IMU: calibration-free attitude compensation (100 Hz update rate).
• Built-in temperature sensor for environmental correction.
• Auto-tuning: adaptive algorithms for automatic gain and range adjustment.
• Dual-frequency output: 200 kHz (shallow) and 33 kHz (deep).
• Android remote control with CHCNAV EasySail for acquisition, display and export.

Performance and benefits
The D60 minimizes system footprint with an integrated sonar and deck unit optimized for unmanned surface vessels. Its calibration-free IMU applies attitude compensation to every depth frame at 100 Hz, remaining stable under sudden roll or pitch excursions beyond 30°. Intelligent auto-tuning adjusts gain and range based on echo intensity and depth, typically applying parameter corrections within 0.2 s to maintain depth integrity in turbid or rapidly changing conditions. The unit supports streamlined workflows via an Android remote controller and CHCNAV EasySail for data acquisition and post-processing.

Typical applications

• Channel dredging
• Estuary surveying
• Reservoir bathymetric surveys
• Canyon and waterway surveys
• Flood emergency surveying

Operation & integration
Operated from an Android remote controller running CHCNAV EasySail for survey control, visualization, data logging and export. Optimized for USV installation with minimal mounting volume; also supported for manned-vessel mounting using appropriate brackets and accessories.

Compatibility
Designed for seamless installation on CHCNAV APACHE series USVs (examples: APACHE 4, APACHE 4 Pro). APACHE 6 supported with a custom bracket.
