New high-resolution scanning sonar from TritechTritech International have announced the launch of the latest addition to the SeaKing family of scanning sonar products - the Hammerhead. The unit can create higher resolution imagery than comparative mechanical scanning imaging sonars, by utilising a large transducer aperture, very fine mechanical step size and proven Digital Sonar Technology.

As standard the SeaKing Hammerhead sonar has two frequencies of operation: A high chirped 935 kHz frequency to enable high resolution imagery, and a second chirped frequency, 675 kHz to allow for long range capability. The wide transducer allows for a very narrow horizontal beam to be created on both frequencies, to increase image resolution.

The Hammerhead has a built in attitude sensor, which makes the unit ideal for tripod deployment, giving the user a clear indication as to the position of the unit relative to the seabed. In addition to the attitude sensor, the unit also has an integrated three axis compass, to allow the sonar image bearing to be continually displayed and updated.

Commenting on the launch, Tritech's Product Line Manager for Imaging Sonars, Ben Grant, said: "The Hammerhead sonar is at the forefront of scanning sonar technology, and is an ideal addition to the well established SeaKing range. The high operational frequency, combined with a wide transducer aperture, makes this the sonar of choice for any application requiring the highest possible resolution of imagery."
