A Powerful New Addition to Our Survey Fleet Hire
The Apache 3 Pro has officially joined our hire fleet, and it is already proving to be a major asset for modern hydrographic and bathymetric surveying. This compact unmanned surface vessel delivers high accuracy, exceptional efficiency, and safer workflows for surveyors working in challenging water environments.
This overview highlights what the Apache 3 Pro offers, how it performs in real survey scenarios, and why it is becoming a go to tool across the industry.

What the Apache 3 Pro Brings to Hydrographic Surveying
Autonomous bathymetric surveying in shallow waters
Designed for lakes, reservoirs, rivers, and coastal zones, the Apache 3 Pro handles environments where traditional boats struggle and where wading simply is not an option.
Integrated GNSS RTK and INS navigation
The combined positioning and navigation system ensures high accuracy even in conditions where satellite signals are interrupted such as under bridges or near built structures.
Built in single beam echosounder
With depth measurement and water temperature sensors, the Apache provides reliable underwater mapping essential for dredging preparation, reservoir management, and siltation assessments.
Lightweight and easy to deploy
A carbon fibre and Kevlar hull provides durability while keeping the vessel light enough for single person deployment.
Hot swappable batteries and intelligent power management
Extended survey sessions are possible without shutting down operations, making the system ideal for long or complex missions.
Autonomous navigation and obstacle avoidance
A millimetre wave radar system detects obstacles and adjusts the route automatically, significantly reducing operational risk.
Real time data collection and monitoring
With 4G and 2.4 GHz connectivity, teams can monitor missions remotely and access data instantly, ideal for fast decision making and efficient reporting.
Where the Apache 3 Pro Excels
Reservoir and dam surveys
Sedimentation and capacity changes can be monitored quickly and accurately, providing vital information for long term asset management.
River and inland water mapping
The Apache delivers precise riverbed profiles, depth mapping, and siltation monitoring, supporting environmental studies, engineering works, and dredging projects.
Urban waterways and under bridge hydrography
The RTK plus INS system allows accurate surveying in areas with signal obstruction, while obstacle avoidance ensures a safe mission.
Shallow water and near shore surveys
In areas where traditional boats cannot navigate, the Apache 3 Pro provides reliable depth data without compromising safety or coverage.
Repeated monitoring and long term studies
Thanks to its speed and repeatability, the system is an excellent choice for time series data such as pre and post dredging surveys or recurring capacity assessments.

Why Surveyors Are Choosing the Apache 3 Pro
Reduced manpower requirements
A single operator can run an entire hydrographic mission without putting personnel on the water.
Improved safety
No need to board unstable boats or work in hazardous shallow water conditions.
Speed and consistency
Traditional methods require more preparation, more staff, and more time. The Apache enables rapid deployment and consistent high quality results.
Modern data workflows
Clean digital outputs integrate directly into CAD, GIS, and hydrographic processing platforms with minimal post processing.
Operational Tips for Best Results
• Pre plan survey routes to optimise coverage • Activate obstacle avoidance when working near structures or debris • Maintain consistent survey settings for repeatable monitoring • Keep spare batteries available to take full advantage of the hot swap system.
A Strong Upgrade for Our Hire Fleet
Adding the CHCNAV Apache 3 Pro to our fleet means providing clients with a high performance tool that improves safety, enhances accuracy, and dramatically increases efficiency on hydrographic projects. Whether for reservoirs, rivers, urban waterways, or environmental monitoring, this system delivers the modern approach surveyors are looking for.
If you would like a comparison between traditional boat surveys and USV based workflows or guidance on building a repeatable monitoring strategy, we are happy to help.
