Recently, the domestically produced accessory - the towing fish ballast wing, independently developed by Tianjin Blue Hole Instrument Co., Ltd., has been successfully applied in multiple marine surveying and underwater engineering projects. Its excellent attitude stability and rapid diving ability have been highly praised by users. This product is designed specifically for EdgeTech 4200 and 4205 series side scan sonar, effectively solving problems such as unstable towing posture and data distortion caused by ocean current interference in shallow water towing operations, providing reliable support for high-precision ocean surveys.
Technological breakthroughs prioritize stability
The core technology of the towed fish ballast wing lies in its optimized wing surface fluid shape, which can generate sustained and stable downforce during the towing process, significantly suppressing the deflection and undulation of the towed fish caused by changes in ship speed or lateral ocean currents. At the same time, with a weight of about 15kg in water, the towed fish can quickly overcome buoyancy and cable resistance, and quickly reach the preset operating depth, especially suitable for shallow water areas with frequent deepening operations. This design not only improves operational efficiency, but also ensures the quality of raw data acquisition from side scan sonar, providing clear and distortion free acoustic images for subsequent underwater pipeline surveys, water subsidence exploration, and channel dredging monitoring.
Non destructive installation, worry free adaptation
As the first customized ballast wing for the EdgeTech 4200/4205 series side scan sonar in China, its structural installation interface perfectly matches the original hole position, allowing for non-destructive and quick installation without any modification to the sonar body. The product is made of high-strength corrosion-resistant alloy material, supplemented by multiple layers of resin protection, which can resist long-term seawater erosion and deck collision, and has excellent weather resistance and durability.
User recognition, broad market prospects
Since its launch on the market, the towed fish ballast wing has been validated in multiple shallow sea, river, and lake mapping projects. User feedback shows that after installing the device, the towed fish maintains a horizontal posture in complex hydrological environments, effectively avoiding the phenomenon of "nodding" or "flipping", and significantly improving image clarity and data consistency. An engineer from a marine geological exploration unit said, "This ballast wing allows our old survey ships to operate stably even in harsh sea conditions, achieving low-cost platform performance upgrades and greatly expanding the applicability of the equipment
Tianjin Blue Hole Instrument Co., Ltd. has always been committed to the localization innovation of marine survey equipment. The successful research and application of towed fish ballast wings not only fills the gap in this field in China, but also demonstrates the company's technical strength in auxiliary stabilization solutions. In the future, the company will continue to cultivate marine equipment supporting products and provide customers with more cost-effective solutions.
