Dunker 6 is a 6G® Wideband®2 Long BaseLine (LBL) and telemetry transceiver specifically designed for vessel deployment. The super duplex stainless steel housing and vibration isolated electronics makes for an extremely rugged dunking system.
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 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.

*TEE Tone Equivalent Energy – WBv2+ signals are 4x the duration (WBv1 & WBv2 are 2x) of Sonardyne tone signals, therefore the TEE figure is to give the user an idea of the operational performance when comparing wideband and tone systems.
