Claim 23:
24. A method of generating a sonar image on the user display of a control head of a consumer sonar system having a transducer unit coupled via a high speed data link to the control head, the transducer unit including a transmit (TX) element, a receive (RX) array, a digital signal processor (DSP), and a multiplexer (MUX) coupled between the RX array and the DSP, the method comprising the steps of:
during a single one transmit-receive cycle,
generating a sonar ping by the TX element to ensonify an ensonification cone of water in which the transducer unit is deployed;
receiving sonar echoes by the RX array resulting from the sonar ping contacting targets in the ensonification cone;

selectively coupling by the MUX at least a first portion of the RX array to the DSP during a first time of the single one transmit-receive cycle and a second portion of the RX array during a second time of the single one transmit-receive cycle;
processing by the DSP the sonar echoes from the single one transmit-receive cycle into sonar display information;
communicating by the transducer unit the sonar display information generated by the DSP from the single one transmit-receive cycle via the high speed data link to the control head; and
plotting the sonar display information generated by the DSP from the single one transmit-receive cycle received from the transducer unit on the user display; and
wherein generation of the sonar ping by the TX element and receipt by the RX array of the sonar echoes resulting from the sonar ping defines one transmit-receive cycle.
