Sonardyne Dunker 6
Dunker 6 is a 6G® Wideband®2 Long BaseLine (LBL) and telemetry transceiver specifically designed for vessel deployment. The super duplex stainless steel housing with shock and vibration isolated electronics makes for an extremely rugged dunking system
Description
Its high power output and Sonardyne Wideband®2 signal processing offers improved operating range and acoustic performance in challenging conditions such as when deployed from noisy vessels or in multipath environments.
The internal Lithium-ion rechargeable battery pack minimises the supply current for long dunker cables. It also enables relocation of the dunker if the cable is cut.
The robust AGP connector on the Dunker 6 is identical to the ROVNav 6 and HPT USBL for compatibility and to reduce spares.
Dunker 6 LBL and telemetry transceiver is fully compatible with Sonardyne’s modem and logging equipment such as AMT and Fetch products, allowing it to be used to retrieve data or configure logging regimes. It supports all of Sonardyne Wideband®2 spread spectrum acoustic communication.
The Dunker 6 system consists of 100 m of cable on a stainless steel cable drum with brake and locking mechanism. The 10 m deck cable between the 48 V Surface Interface Unit (SIU) and the cable drum allows the drum to be conveniently located. The connection to the cable drum is via an easily replaceable 8-way SubConn.
