SeaKingTowfish DST

Sidescan Sonar

The SeaKingTowfish Sonar System is an extremely compact and cost effective, high definition sidescan sonar system. It is designed for a wide range of seabed survey and inspection duties. The 300kHz frequency has a useful range up to 200 metres either side. The fish combines the very latest Tritech DST (Digital Sonar Technology) electronics with industry leading transducer design and digital CHIRP signal processing techniques to dramatically improve range resolution and generate sonar images of unprecedented clarity. The sonar "fish" is designed to be easily deployed by hand with excellent stability under all towing conditions. Fitted with durable polycarbonate stabiliser fins, in the event of ground contact the fins will break away and are retained for recovery by a shock cord line. The fish has a weak link and safety recovery line. If it hits an obstruction the weak link will part but the "fish" will not be lost. The towfish is small and light and may be manually deployed and operated by a single person from very small boats thus making it ideal for inshore and coastal applications. In common with all Tritech sonar systems, SeaKing sidescans may be connected to a SeaKing SCU surface control and display unit or most PC's. In addition to the display of sidescan data, the system will take position input from DGPS. This information is recorded with the sonar data to allow a "fix" of a target. The customer's own bit map chart may be displayed on the same screen as the sonar data. All data produced by the subsea towfish is processed within the fish and transmitted to the surface in digital format. All data may be stored on the built-in hard disk drive, in the surface control unit. The post processing export facility will convert the logged data to XTF and CSV formats for third party software packages.
