The Sonardyne Wideband Sub-Mini (WSM) is a versatile and compact subsea USBL transponder/responderdesigned for precise positioning of ROVs, towfish, and other mobile subsea targets. It operates in water depths up to 3,000 meters, providing superior ranging accuracy and enabling operations in multi-user, multi-vessel environments. The WSM supports Sonardyne’s Wideband® signal technology, which offers fast USBL position updates and enhanced signal clarity.
The WSM is available in two models Type 8071: Rated to 1,000 meters, featuring an omni-directional transducer and Type 8070: Rated to 3,000 meters, with a high-power directional transducer that provides acoustic output comparable to Sonardyne’s largest seabed transponders.
Both models include a depth sensor for improved USBL positioning accuracy, and an external On/Off switch for easy operation and storage. They can operate in both transponder and responder modes and are powered by long-life NiMH batteries.
