what we said at the time

Sonardyne’s family of Wideband Sub-Minis (WSM) are a versatile range of USBL beacon/ responders designed for positioning ROVs, towfish and other mobile targets in water depths up to 4,000 metres.

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. In addition to supporting new Sonardyne Wideband® signals, WSMs also support traditional Sonardyne tone and HPR 300 and HiPAP® channels. A link allows the WSM to be configured for use with all of the popular MF frequency acoustic navigation systems.

The Type 8071 WSM – USBL Beacon is equipped with an omni-directional transducer and is depth rated to 1,000 metres making it suitable for a wide ranger of general USBL tracking application.

The Type 8070 WSM – USBL Beacon is a 4,000 metre rated unit and features a high-power directional transducer with an acoustic output comparable to Sonardyne’s most powerful full size seabed transponders.

Both types of WSM have a depth sensor fitted as standard to aid USBL positioning accuracy and an external On/Off switch for ease of use and storage when not in use.

The Type 8070 WSM is also available with the ability to activate an external release mechanism.

Title	Description
Changes To The Depth Rating of Type 8070 Wideband Sub-Minis – No: 09 002	Announment that all Type 8070 Wideband Sub-Mins have been re-classified from a 3,000 metre depth rating to 4,000 metre depth rating.
WSM Chargers –No: 08-007_02	Due to batch tolerances, it has been found that the voltage output by a WSM charger at the end of the charge process (when the current drops to a trickle charge), can rise to 30 V or even higher. This high voltage has caused some failures to occur in transponders when they transmit an acoustic pulse.
Wideband Sub-Mini Spring Loaded Vent – No: 08-004	To reduce the risk of deploying Wideband Sub-Mini beacons without fully closing the pressure relief valve a sprung loaded pressure relief valve has been introduced. The new pressure relief valve has been incorporated in all new units effective from 25th February 2008. The new pressure relief valve is gold in colour (original valves are red) and is designed to fit flush with the switch end cap name plate when closed.
Installation Guide for Spring Loaded Vent Valve Kit on Type 8070 WSM Transponders – IG-8070-047-A0_2_	This guide details the procedure involved in installing a sprung loaded vent valve on Type 8070 Wideband Sub-Mini Transponders.
