Building on the success of our advanced side scan sonar systems Tritech announces the next generation model, the SeaKing Towfish SK150 DST. Specifically designed to fly at depths of up to 250m (820ft), the SK150 can be used for high resolution surveys at depths other lighter systems can't reach.
The SK150 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.
There are two frequency options available for the SK150, with either the basic 325kHz monolithic transducer assembly or the advanced 150kHz composite transducer assembly providing superior image quality and longer range.
The SK150's simple, modular design provides increased reliability and facilitates quick in-field repairs should any damage occur during operation. All electronics are located in a single subsea pressure housing isolated from the rest of the towfish. The stabilising fins can be cheaply and easily replaced and a simple sheer and recovery mechanism is provided in the event of the SK150 becoming snagged.
The Tritech Micron Echosounder is available as a fully integrated optional extra for the system when towfish altitude information is of importance.
As part of the Tritech SeaKing suite of survey sensors, it is possible to run the SK150 with other SeaKing sensors over one communication link. The SeaKing Towfish SK150 DST may be connected to a Seanet SCU surface control and display unit or most standard laptops and PC's with Tritech Seanet Pro software installed. In addition to the display of side scan sonar data, the system will take position input from DGPS. This information is recorded along with the sonar data to allow a 'fix' of a target.
The SK150 is fully compatible with all Kiltec and Easyreeling electric winches.
