SV1216 Dynamic Imaging Sonar

The SV1216 is a low-cost, maintenance-free, 2D forward-looking multibeam imaging sonar that provides acoustic vision ahead of the vehicle in clear or turbid water, enabling target detection and recognition, collision avoidance, and obstacle detection. Its key features include low cost, small size, light weight, and low power consumption.

Thanks to special design and manufacturing processes, this sonar is priced significantly lower than our other 2D multibeam sonars and lower than the vast majority of comparable products on the market. In addition, the sonar housing is made entirely of corrosion-resistant, low-permeability materials, allowing it to operate continuously in seawater for several weeks without needing cleaning.

The SV1216 is a single-frequency design, currently offering frequencies of 700kHz, 900kHz, and 1.2MHz, with other frequencies available upon customization.

The SV1216A features a 316 stainless steel housing, while the SV1216B features a carbon fiber housing. The carbon fiber housing is lighter and can achieve neutral or slightly negative buoyancy in water. All other specifications are identical.

The maximum operating depth of the SV1216 is 100 meters.

Three-view drawing and mounting holes:

This sonar can be used continuously in seawater for several weeks without maintenance. However, the sonar surface must be checked regularly for marine biofouling and cleaned promptly, otherwise sonar performance may be affected. In addition, rinse the unit thoroughly with fresh water and wipe dry each time it is taken out of the water;

The sonar must not be exposed to direct sunlight for extended periods, as this can significantly affect its service life;

If a product capable of long-term underwater operation is required, please be sure to specify when ordering (-LT option). Our company will adopt special materials and processes accordingly.
