Abstract
Abstract A hand-held LCD game machine is used as a hand-held LCD fish finder, in addition to its original game functions. Instead of a typical ROM game cassette, another device, which includes a cassette portion, a main body, and a float sensor having an ultrasonic transmitter, is inserted into the LCD game machine, so that the topography of the water bottom and the fish in water are displayed on a LCD panel by means of a program ROM having a memory to display the same based on an echo signal issued and received through the ultrasonic transmitter.
