DIDSON™ sets a new standard for high-definition sonar imaging. This "Acoustic Camera" gives near video quality images for inspection and identification of objects underwater. It is a surrogate for optical systems in turbid water. The standard DIDSON operates at two frequencies (1.8 MHz and 1.1 MHz) and provides images of objects from 1 m to over 30 m in range. DIDSON LR operates at 0.70 MHz and 1.2 MHz images objects up to 80 m in range. DIDSON is compact and requires only 30 watts of power. Our current models can operate at depths from 100 m to 3000 m.
