MiniUAC-1210    Forward-Looking Sonar

Ultra-High-Frequency Short-range high-precision imaging

The MiniUAC-1210 sonar operates at dual frequencies of 1.8 MHz and 3 MHz, providing near-optical imaging resolution. It is specifically designed for short-range, high-precision imaging applications such as close-range target detection and inspection, and can serve as an alternative to optical imaging in turbid water environments.

Product Description


The MiniUAC-1210 ultra-high-frequency forward-looking sonar is currently the highest-frequency sonar in our product line. The ultra-high operating frequency delivers significantly enhanced resolution, achieving detection performance close to optical imaging. This product is dedicated to short-range, high-accuracy imaging tasks, including close-range target detection and inspection, and can partially replace optical imaging in turbid water conditions.

The currently marketed MiniUAC-1210B is the latest version in the MiniUAC-1210 series. Compared with the previous version, this upgrade improves the signal-to-noise ratio, increases the refresh rate, and extends the detection range. Other specifications and mechanical characteristics remain essentially unchanged.

The MiniUAC-1210B operates at two frequencies: 1.8 MHz and 3 MHz. Other frequencies can also be customized.
