Customers of Sonardyne International Ltd are set to benefit from two valuable performance upgrades for their equipment.

Users of the Sonardyne Type 8070 Wideband Sub-Mini (WSM) transponder/ responders have been informed that the depth rating of their equipment has now been upgraded from 3,000 to 4,000 metres.

This follows an engineering design review prompted by customers’ desire to operate the units at greater depths. The change not only applies to newly manufactured WSMs but all Type 8070 units currently in the field. No mechanical modifications or new parts are required to benefit from the extended depth capability.

Users wishing to re-label their WSM end-caps, which currently indicate the 3,000 metre rating, can obtain a replacement label free of charge by contacting Sonardyne’s customer support team by email at
Sonardyne’s successful Ranger USBL acoustic positioning system has also been upgraded, taking the operating range limit from 2,000 metres to over 6,000 metres. This means that the system now provides users with the same range capabilities as the company’s more advanced Ranger-Pro system.

All new Ranger USBL systems scheduled for delivery from October 2009 onwards will be delivered with the extended range capability. There is no change to the specification of Ranger-Pro USBL which will continue to provide more advanced features such as additional target tracking, ping stacking for fast position updates and support for legacy transponders.

Existing Ranger USBL users and customers who have recently taken delivery of a Ranger USBL are being invited to contact Sonardyne customer support to arrange their free of charge software update.
