The SeaKing Towfish SK150 has beenspecifically designed to fly at depths of up to120m. This means the SK150 can be used forhigh resolution survey at depths lighter systemscannot reach.

Combining the very latest in digital sonartechnology with industry leading transducerdesign and digital CHIRP signal processingtechniques dramatically improves rangeresolution and generates sonar images ofunprecedented clarity. The advanced transducerassembly provides superior image quality andlong range.

With a simple, modular, design the SK150provides increased reliability and facilitates in-field repairs should any damage occur duringoperation. All the electronic equipment is locatedin a single pressure housing isolated from therest of the towfish. The stabilising fins can beeasily replaced and a simple shear and recovermechanism is provided in the event of the SK150becoming snagged.

The SK150 is easy to deploy and recover andis fully compatible with all Kiltec and Easyreelingelectric winches.

As part of the Tritech SeaKing range of devicesthe SK150 is easy to integrate with other SeaKingsensors to provide a complete survey package.Additionally the SK150 can be connected to aSurface Control Unit (SCU) or SeaHub wheredata from a GPS device can be combined withthe sonar records to allow accurate fixing offeatures on the sea floor. The sonar data canbe viewed live or recorded for later viewing orexport to a variety of formats such as XTF, TIFF,GeoTIFF and Google Earth kMZ.
