TDU Deck Control Unit

The TDU Deck Unit is meticulously developed by Tiandun High-Tech (Beijing) Technology Co., Ltd., specifically designed to accompany its Sino-ART series acoustic releases and acoustic communication modules. During vessel operations, the TDU Deck Unit uses its transducer to accurately send commands to the acoustically released devices (or acoustic communication modules) deployed underwater and effectively receive acoustic feedback signals from these devices. This interactive process ensures the smooth realization of key functions such as release and recovery, communication, and precise ranging.contactus
