MiniUAC-1206   Forward-looking Sonar

2D forward-looking multibeam imaging sonar 

For users with more stringent requirements on size, weight, and cost, the MiniUAC-1206 is a better choice. Compared with other forward-looking sonar models in the same product family, the MiniUAC-1206 features a smaller size, lower weight, and a highly competitive price, while maintaining uncompromised performance.

The MiniUAC-1206 supports dual-frequency operation, offers a maximum detection range exceeding 100 m, and provides selectable operating frequencies from 700 kHz to 1.8 MHz. An integrated obstacle avoidance algorithm assists users in identifying obstacles ahead.

Overview

Product Description


The MiniUAC-1206 series micro forward-looking sonar is a 2D forward-looking multibeam imaging sonar capable of providing forward acoustic vision in both clear and turbid water environments. It enables target detection and identification, obstacle avoidance, and hazard detection. Key characteristics include compact size, light weight, and low power consumption.

Compared with similar products available both domestically and internationally, this product delivers high performance at a highly competitive price, while offering more frequency options, smaller dimensions, and lower power consumption. In addition, most configurations are available from stock for long-term supply. For non-stock configurations, the typical delivery time is within one month.

The MiniUAC-1206E, currently on sale, is the latest version in the MiniUAC-1206 series. It supports multiple frequency bands, including 700 kHz, 750 kHz, 1.1 MHz, 1.2 MHz, and 1.8 MHz. Other frequencies can be customized upon request. The sonar adopts a dual-frequency design, and the two operating frequencies can be switched via software.

The standard models support maximum operating depths of 300 m and 1.5 km. For deeper operating depths, please contact us.
