Deploying Commercial Sonar in Your Marine Surveying Tool Box
Navigating complex marine environments requires highly specialized sensors. True hydrographic and recovery operations rely on different types of sonar arrays to build an accurate picture of the bottom. Silt, currents, or total darkness frequently hide these targets. Therefore, teams must choose the right tool for the job to ensure data collected aligns with commercial IHO hydrographic survey standards.
1. Side Scan Sonar Systems
Side scan sonar is the primary tool for covering large areas of the seafloor rapidly. To use it, you tow a sonar transducer behind a vessel. This device emits dual-sided acoustic beams. As a result, the returning echoes construct an incredibly detailed image of the bottom topography.
SSS-600kHz Side Scan Sonar: This model is optimized for high-resolution imaging at mid-range distances. Furthermore, this system is a staple for public safety dive teams. It helps locate smaller targets like submerged vehicles, discarded evidence, or drowning victims. Its frequency balance provides sharp target definition without sacrificing necessary swath width.
SSS-450/900kHz Dual-Frequency Side Scan Sonar: This unit is the ultimate multi-mission tool. For example, the 450kHz frequency allows for wide-area searching to locate anomalies quickly. After that, switching to the ultra-high 900kHz frequency provides unparalleled micro-detail to confirm target identity before deploying divers or an ROV.
2. Scanning Sonar
Unlike a towed array, a scanning sonar is typically deployed from a stationary position. For instance, you can set it on a tripod on the seabed or mount it directly onto an underwater ROV. The transducer head rotates 360 degrees. Consequently, it provides a continuous, real-time view of the surrounding environment. Therefore, it is an indispensable tracking and safety asset when operations require monitoring divers. It is also excellent for positioning equipment around structures, bridge pilings, or dams in zero-visibility conditions.
3. SBP-1 Sub-Bottom Profiler
Sometimes, the target isn’t sitting on top of the seabed. Instead, it is buried beneath layers of sediment and silt. Standard side scan systems cannot see these objects. For this reason, the SBP-1 Sub-Bottom Profiler becomes essential. By utilizing lower acoustic frequencies, this sub-bottom profiling sonar penetrates the ocean floor. As a result, it sends back echoes that map geological layers. This reveals buried structures, pipelines, historical shipwrecks, or missing objects that have settled deep into the mud over time.
Commercial Sonar Engineered for Public Safety and Recovery
For police departments, sheriff departments, and fire rescue dive teams, time is always against you. Search operations must be precise, efficient, and well-documented. Because of this, our line of underwater search and recovery gear is built specifically to streamline these critical operations. It also helps your team meet NFPA 1006 standards for public safety dive operations.
| Critical Search & Recovery Metrics | Operational Capabilities |
| Target Frequency Range | 450 kHz (Search) / 900 kHz (Identification) |
| Typical Swath Width | Up to 600 feet (180 meters) per side |
| Visibility Requirement | 0% (Pure Acoustic Imaging) |
Using high-frequency commercial sonar arrays removes the dangerous guesswork out of diving. Instead of sending divers into hazardous, black-water environments to perform manual grid searches, a vessel can tow a side scan array. As a result, you can map miles of river or lake bed in a fraction of the time. Once a definitive anomaly is identified on the display monitor, dive teams can deploy straight to the coordinates. Consequently, this significantly reduces bottom time and increases overall team safety.
Advanced Software & Deployment Accessories
Hardware is only half of the equation. Processing and interpreting the acoustic data is what turns data into actionable intelligence.
Sonar View Software: This powerful processing suite integrates seamlessly with our sonar hardware. Specifically, it offers real-time scrolling imagery, target marking, coordinate tracking, and post-mission analysis. It allows operators to precisely measure target length, width, and shadow height to estimate physical dimensions before entering the water.
Sonar Coverage Map: Plan, track, and record your search grids with absolute certainty. This mapping interface ensures that your vessel maintains proper lane spacing during a search. Therefore, it eliminates gaps in your sonar coverage. It also provides clean data logs mapped out in standard UTM coordinate systems for agency reporting.
CMS-1 & CMS-2 Cable Reels: Managing high-bandwidth data cables on a moving boat can be a logistical nightmare. However, heavy-duty slip-ring cable reels allow continuous data transmission while paying out or reeling in cable. As a result, they prevent kinks and preserve the integrity of your tether line.
DDW-1 Depressor Wing: When towing a sonar towfish at deeper depths or higher speeds, cable drag tends to lift the transducer toward the surface. Fortunately, the DDW-1 Depressor Wing uses hydrodynamic downforce to keep the towfish stable. This keeps it locked at the correct operational depth, ensuring a clean, undisturbed acoustic signal.
