Claim:
A radio-controlled fish locating system for searching solid objects and receiving information on water temperature and depth of a body of water as well as underwater terrain at a bottom surface of the body of water, said radio-controlled fish locating system comprising: a watercraft adapted to view the underwater terrain and the solid objects, said watercraft including a watercraft control module, further comprising: first and second hulls disposed in a parallel orientation; a deck intermediately connected to said first and second hulls; a plurality of motors having a plurality of shafts respectively; a plurality of propellers connected to said shafts respectively; a plurality of propeller covers enclosing said propellers for protecting and directing airflow thereof; and, a threaded deck aperture located on an underside of said deck; a controller including a controller control module and a display screen connected thereto, said controller control module generates and transmits a first radio-frequency (RF) signal to said watercraft control module for controlling an operation of said watercraft, and a controller electric circuit further comprising: a controller battery; a controller power switch electrically coupled to said controller battery; a plurality of menu control buttons electrically coupled to said controller power switch; first and second joysticks electrically coupled to said controller power switch and said controller control module; a controller antenna electrically coupled to said controller control module; and, a display screen electrically coupled to said controller battery and said controller control module respectively; a sonar buoy removably attached to said threaded deck aperture, said sonar buoy generating and transmitting a sonar signal into the water for detecting the solid objects as well as the underwater terrain and water temperature and depth; wherein said first RF signal controls a speed of each of said motors and a speed of each of said propellers respectively; wherein said watercraft transmits a second RF signal to said controller and thereby provides said controller with information including a size, a composition, and a shape of the solid objects as well as the water depth, temperature and underwater terrain acquired from said sonar signal; wherein said controller control module directs operation of said first and second joysticks and said display screen; wherein said display screen displays information received from said sonar buoy; wherein said controller battery generates a current carried to said controller power switch and said menu control buttons, wherein said display screen is controlled via manipulation of said menu control buttons; and, wherein said information is displayed graphically on said display screen.
