Applications
Sonar Solutions
Hydrographic Surveys
Coastal & port charting
Conduct precise hydrographic surveys using our single beam echosounders to chart water depths, map coastlines, and support port and harbour development.
Bathymetry Mapping
Seabed profiling
Generate accurate bathymetric profiles of lakes, rivers, and ocean floors for dredging planning, environmental monitoring, and resource assessment.
Inland Waterway Surveys
Navigation & sedimentation
Survey navigational channels, reservoirs, and inland waterways to ensure safe passage depths and monitor sedimentation over time.
Seabed Classification
Substrate & habitat analysis
Analyse echo return signals to classify seabed substrates — distinguishing sand, rock, mud, and vegetation for marine habitat studies.
Dredging Support & Monitoring
Pre & post-dredge depth
Monitor pre- and post-dredging depths with high accuracy to ensure proper material removal and maintain navigable waterways.
Port & Harbour Management
Berth & sediment monitoring
Support safe vessel operations by continuously monitoring harbour depths, berth conditions, and sediment buildup.
Flood Monitoring & River Studies
Cross-sections & hydrology
Measure river cross-sections and depth variations to support flood modelling, erosion studies, and water resource management.
Offshore & Coastal Engineering
Structures & route planning
Provide essential depth and seabed data for offshore structures, coastal construction, and pipeline or cable route planning.
Environmental & Habitat Monitoring
Ecosystem & conservation
Monitor aquatic ecosystems by mapping underwater vegetation, sediment changes, and habitat structures.
Search & Recovery Operations
Object detection & anomalies
Detect underwater objects and depth anomalies for search, rescue, and recovery missions in lakes, rivers, and coastal waters.
Engineered Performance
Built from the ground up to solve complex subsea challenges with unparalleled reliability.
High Precision Measurement
Achieve survey-grade accuracy with ultra-low noise electronics and advanced acoustic arrays.
Advanced Signal Processing
Proprietary algorithms deliver clean, reliable data even in environments with high acoustic interference.
Real-time Data Output
Seamless streaming of bathymetric metrics via industry-standard protocols directly to your dashboard.
Rugged & Compact Design
Titanium housing with 1000m depth rating ensures durability without compromising on weight and form factor.
Low Power Consumption
Optimized architecture suitable for extended deployments on Autonomous Underwater Vehicles (AUVs).
Multi-frequency Operations
Pulse-compression and CHIRP support for enhanced range resolution in diverse sediment classifications.
How It Works
The core principles behind our robust sonar technology.
Emit Pulse
Transducer emits targeted acoustic waves into the water column.
Reflection
Waves bounce off the seabed or submerged objects and return.
Processing
Advanced algorithms filter noise and calculate precise depth/distance.
Output
Clean bathymetric data streamed to navigation or survey software.
