Datasheet
Wideband Sub-Mini Remote Transducer

Sonardyne's family of Wideband Sub-Minis (WSMs) are a versatile, high performance range of USBL transponder/ responders designed for positioning ROVs, towfish and other mobile subsea targets.

Compact and rugged, WSMs incorporate the latest Sonardyne Wideband® signal technology which offers superior ranging accuracy, operation in a multi-user, multi-vessel environment and fast USBL position updates.

The Type 8071-000-07 WSM is a 1,000 metre depth rated unit equipped with a cable connected omni-directional remote transducer.

The remote transducer feature offers users the maximum flexibility when installing the WSM on a vehicle such as an AUV where space is often restricted. The electronics bottle can be mounted internally within the vehicle whilst the transducer can be located externally ensuring clear line of sight with the surface.

The remote transducers are also compatible with Sonardyne Wideband Mini Transponders and AV-Trak 2 LBL transceivers.
