General-purpose 2D Imaging Sonar for gaining a visual in murky or dark water. The M750 is a 750kHz/1.2 MHz Multibeam sonar. The Dual Frequency Mode provides even more detail in a smaller window. Longer range capability than other imaging sonars (0.1m to 120m) but offers lower quality imagery in comparison to the M1200, best suited for navigation, inspections, and search and recovery missions.
