PRODUCT DESCRIPTION
-
High-Precision Navigation
Maintain consistent survey accuracy even in GNSS-denied environments. The integrated GNSS RTK and Inertial Navigation System ensures precise positioning under bridges, along urban waterways, and in other signal-obstructed areas.
-
Advanced Depth Survey
Deliver reliable and accurate bathymetric data using the CHCNAV D270 single-beam echosounder. Its integrated water temperature sensor corrects sound velocity in real time for enhanced depth measurement performance.
-
Smart Power Control
Stay mission-ready with an intelligent power system that supports hot-swappable batteries. In case of interruption, the Apache 3 Pro resumes its route from the exact point of disruption, ensuring operational continuity.
-
Adaptable Performance
Engineered with high-sensitivity, anti-interference transducers and adaptive bathymetric algorithms, the Apache 3 Pro adjusts automatically to variable water terrains, delivering high-resolution data in complex survey scenarios.

Product Details
Anti-Entanglement Design
Titanium alloy mesh guard and hybrid water pressure conversion greatly reduce weed entanglement. Real-timeself-diagnosis alerts operators to obstructions, protecting the motor.
Semi-Embedded High-Speed Motor
Max motor speed up to 7200 RPM, supporting a top vessel speed of 7 m/s. Single battery set provides up to 10 hours of endurance at 1.5 m/s.
