Sonardyne are known for their high-end USBL solutions, which is a very relevant product to turn to if you wish to increase the positioning during survey and inspection operations – and to do so at an attractive price compared to similar solutions on the market.

This product is available as an add on, that is, additional beacon(s), to the Sonardyne Mini-Ranger 2 system with WSM6+ transponder package, which is put together for operations on vessels that need survey grade positioniong performance without the cost and complexity of a deep water USBL solution. This includes integration with the EIVA ScanFish ROTV (remotely operated towed vehicle).

The latest Sonardyne Wideband 2 signal technology has been incorporated on the WSM6+ (Wideband Sub-Mini 6 Plus), which offers superior ranging accuracy and fast USBL position updates. Moreover, it offers full two-way Wideband support – interrogation and reply signals.

WSM 6+ has 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.
