The dual-frequency 900 kHz and 2250 kHz provide the most versatility of any 2D imaging sonar. The 900 kHz offers high-resolution long-range navigation, object detection, and obstacle avoidance, while the 2250 kHz provides ultra-high-resolution at close range. ROV navigation, hull inspections, structure inspections, diver monitoring, and search and recovery are a few applications that benefit from the dual-frequency’s imaging capabilities.
