Wideband Sub-Mini 6 Plus (WSM 6+) Release Transponder

What you need to know

Full two-way Sonardyne Wideband 2 interrogation and reply – mitigates interference and multi-path issues
More than 500 unique Sonardyne Wideband 1 and 2 addresses
Sonardyne Wideband 1 and HPR 400 navigation compatible
Choice of 1,000 m and 4,000 m depth rating

The Wideband Sub-Mini 6 Plus (WSM 6+) Release transponder is an extension to our latest generation of versatile USBL transponders/responders that support Wideband®2 signals. The WSM 6+ release is designed for rapid free fall deployment and recovery, ideal for a temporary seabed reference. The integrated screw release mechanism is based on the field proven LRT design and suitable for deployment up to 4000 metres.

More about this product

WSM 6+R Overview & Datasheet

The compact and rugged design is based on the field proven WSM mechanics and is available in MF Directional and MF Omni-Directional versions. Our latest Wideband 2 signal technology has been incorporated, which offers superior ranging accuracy and fast USBL position updates.

The WSM 6+ improves on its predecessors by offering full two-way Wideband support – interrogation and reply signals. All Wideband 2 signals are supported. Legacy support is also available for Wideband V1 and HPR 400. The configuration is programmable using supplied software and a serial link or it can be configured acoustically via iWAND. This allows the WSM 6+ to be configured for use with all of the popular MF frequency acoustic navigation systems.

The Type 8370-1171 WSM 6+ is equipped with an Omni-directional transducer and is depth rated to 1,000 metres making it suitable for a wide range of general USBL tracking applications.

The Type 8370-4172 WSM 6+ is depth rated to 4,000 metres and features a higher power directional transducer.

Both types of WSM 6+ have a depth sensor fitted as standard to aid USBL positioning accuracy and an external on/off switch to save the battery when not in use.

WSM 6+ variants are available with acoustically controlled output lines suitable for external motor drive, burnwire or contact closure releases.
