A motorized, radio-controlled practice fish for improving a operator's casting
ability is disclosed. The practice fish can detect a lure in two different modes,
active or passive. When in active mode, the practice fish responds to signals sent
by a lure having an IR transmitter. When in passive mode, sensors within the practice
fish respond to light signals emitted at a certain frequency and wavelength reflected
from a lure back to the practice fish. An instructor can move the practice fish
using a remote control device, or the practice fish can be set in one of several
traveling modes.
