PRODUCT DESCRIPTION
-
Rugged hull design
Constructed with high-strength, high-modulus carbon fiber and HPT one-piece molding technology, the hull achieves a strength of up to 10 MPa, significantly enhancing its collision resistance. The motors are equipped with mesh covers, reducing the risk of deformation upon impact.
-
Anti-Tangle Design
The APACHE 4 Pro features a titanium alloy mesh cover combined with hybrid water pressure conversion technology, significantly reducing the risk of entanglement by aquatic vegetation. If the motor does become entangled, the system triggers a software alarm to help ensure motor safety.
-
Multi-Sensor Support
With a 50 kg payload capacity and a 24 cm central access shaft, the APACHE 4 Pro supports ADCPs such as the CHCNAV RiverStar Series, M9, RiverPro, and RioGrande. It also accommodates the CHCNAV HQ-400 multibeam echo sounder, side-scan sonar, and water quality monitors end-to-end survey solutions.
-
Advanced Echosounder
The APACHE 4 Pro features high-sensitivity, anti-interference transducers combined with residual vibration elimination technology. Its advanced bathymetric algorithms support adaptive parameter adjustment, enabling reliable performance in complex underwater terrain and diverse water environments.
