. . . "A deep water multi-beam echo sounder which uses an operating frequency of 15.5 kHz to determine bathymetric depth. As a special feature, it contains extended coverage of 2x 60 degrees (with 1 or 2 x 59 sound beams, each with approximately 2, 3 degree beam width). Available transducers are T-type arrays. The system has a depth range of 10 to 11,000 m. This is the 2nd generation of the Hydrosweep DS. Atlas Hydrographic is now part of the Teledyne Reson group."@en .
