Description

The Analog Dual Frequency Side Scan Sonar is a tool for seabed feature mapping, offering high quality results in a  simple and reliable package. It offers switch selectable dual frequency operation (114 / 410 kHz). The towfish  is available in depth ratings of 1000 m and 2000 m.

The standard system employs a lightweight towfish (Model 159D), which is easily deployed by one person. It houses a multiplexer  (Model SS982), allowing data transmission over long  cables, as well as the two dual frequency transducers (model 196D port and starboard). The transceiver unit (model SS981) outputs a signal compatible with all major acquisition systems.

The Tranceiver deck unit allows the operator a simple means  to select operation parameters such as operating  frequency, Gain, Time Varying Gain (TVG) and  Automatic Gain Control (AGC), with duplicated  controls for the port and starboard channel.

The Towfish was designed as an easily deployable  stable platform for versatile operations.  The Multiplexer is the sub-sea processing unit. It  holds all transmit, receive and multiplexing electronics  and uses standard sub-sea connectors to  the transducers and tow cable, thereby ensuring that transmission  power is not lost over the tow-cable and reducing the risks  of high voltage defects.
