According to a preferred aspect of the instant invention, there is provided a synchronized sonar apparatus that is suitable for use when multiple sonar units are used in close proximity with each other. In a preferred embodiment, the instant invention reduces or eliminates interference between adjacent sonar units by electronically interconnected all of the sonar units and causing them to activate or "fire" at the same time. As a consequence, all of the units will also be "listening" for the returning reflections at the same time. Thus, cross-unit interference will be largely eliminated. Additionally, in another preferred embodiment there is provided a sonar system wherein the sonic sources are electronically interconnected and fired according to a predetermined timing rule, wherein the timing is chosen so that the firing transducers do not interfere with each other.
