Product Overview

WSM 6+ is one our most popular USBL transponders, selected by customers for its small size, value and dependable performance in all environments, shallow or deep.

It’s the perfect choice for fitting to observation and work-class ROVs, towfish, submersibles and equipment being deployed onto the seabed for short durations.

WSM 6+ is compatible with all of our Ranger 2 USBL systems – we even include one with every Ranger 2 Standard – as standard.

The compact and rugged design is based on the field proven mechanics from previous generation designs and is available with omni-directional or directional transducers. The omni version is depth rated to 1,000 m; the directional is depth rated to 4,000 m.

Both versions support transponder and responder operating mode if an external trigger from your platform is available. Responder mode provides significantly faster position updates than transponder mode.

WSM 6+ supports Wideband 2 acoustic signals and legacy Wideband 1 and HPR 400. The configuration is programmable using supplied software and a serial link or it can be configured acoustically via our back deck handheld test unit, iWand. This allows the WSM 6+ to be configured for use with all of the popular MF frequency acoustic navigation systems.

Both types of WSM 6+ are also fitted with 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.
