ABSTRACT:
The present invention entails a multi-channel fishscope that includes an expandable microprocessor unit that is adapted to receive echo profile signals from one or more transmitter-receiver modules and through voltage comparatory networks generating an output video signal that is directed to a CRT of a television monitor. There the echo profiles are transformed into signature traces on the TV monitor that represent fish or other target objects. By the provision of a search/scan module with timing control provisions, the depth of the traces is scaled onto the TV monitor in order to indicate depth and relative position.
