The Imagenex Model 837B Delta T 120 kHz is a high resolution multiple receiver sonar system run from a laptop or industrial PC computer. In this model, the acoustic array is designed to provide detection over a 120 x 2.5 field of view for bottom profiling applications. The 2.5° field of view is also applicable to obstacle avoidance in near-bottom applications where the narrow vertical extent of the beam reduces false obstacle detection. A 120 kHz acoustic frequency has been selected to provide detection up to 300 m range. Image update rates are up to 20 times per second at short range and more than 5 times per second at 100 m range. The stainless steel housing provides a 1000 m depth rating for compatibility with ROV and AUV applications.
