Abstract: Many different types of systems are utilized and tasks are performed in a marine environment. The present invention provides various configurations of castable devices that can be operated and/or controlled for such systems or tasks. One or more castable devices can be integrated with a transducer assembly, such as a phased array, that emits sonar beams and receives sonar returns from the underwater environment. Processing circuitry may receive the sonar returns, process the sonar returns, generate an image, and transmit the image to a display.

Abstract: A sonar transducer assembly is provided including a transducer configured to transmit one or more sonar beams into an underwater environment, a housing that holds the transducer, at least one electrical cable that enables electrical signals to be transmitted between the transducer and a computing device, and a conductive enclosure disposed around at least a portion of the transducer and electrically connected to a ground line of the electrical cable to create a shielded volume. The conductive enclosure reduces an electromagnetic field within the shielded volume.
