Rugged Carbon Fibre Hull:
Built from high-strength, high-modulus carbon fibre using HPT one-piece moulding technology, the Apache 4 Pro hull achieves 10 MPa impact resistance. Motor mesh covers further protect the propulsion system against collision damage - essential when operating close to bridge piers, lock walls, and other underwater infrastructure.
Anti-Entanglement Protection:
A titanium alloy mesh guard combined with hybrid water pressure conversion technology significantly reduces the risk of aquatic vegetation and debris fouling the propulsion system. If entanglement is detected, a software alarm alerts the operator before motor damage can occur - protecting both the mission and the equipment.
Wide Sensor Compatibility:
The Apache 4 Pro's 50 kg payload and 24 cm central access shaft support a wide range of survey sensors. Compatible ADCPs include the CHCNAV RiverStar Series, Teledyne M9, RiverPro, and RioGrande. The platform also accepts the CHCNAV HQ-400 multibeam echosounder, side-scan sonar, and water quality monitors - making it a genuinely versatile multi-programme survey platform.
High-Resolution Echosounder:
High-sensitivity, anti-interference transducers and adaptive bathymetric algorithms enable reliable depth measurement across complex underwater terrain and variable water conditions. Residual vibration elimination technology ensures clean data even when the vessel is operating at speed or in turbulent flow.
Android Remote Control with EasySail
The Android remote controller connects via 4G and 2.4 GHz for up to 1 km of reliable range. The EasySail app handles route planning, real-time data and video feedback, data collection, and post-processing from a single interface - no separate laptop required in the field.
Automated Sound Velocity Profiling:
An optional automatic sound velocity profiler kit integrates with the remote controller and can be installed or removed in under one minute. For multibeam echosounder surveys, real-time sound velocity correction is essential for depth accuracy - this optional kit delivers it without adding significant operational complexity.
