The present invention comprises a transmitter unit having at least one infrared (IR) transmitter, a target screen, a plurality of photodiode sensors disposed in a spaced apart relationship about the target screen, and receiver circuitry connecting the photodiode sensors together. The transmitter unit continuously emits an IR signal, which is detected by the photodiode sensors. The receiver circuitry then triangulate the position of the transmitter unit by calculating the differential distances between each of the photodiode sensors and the transmitter unit. The receiver circuitry is able to dynamically update the position of the transmitter unit because the transmitter unit continuously emits an IR signal. The transmitter unit is able to simulate a “shot” in a number of different ways, including updating the packet update rate or altering the data packet preamble. No return signal is necessary for the transmitter unit to confirm the “shot.”
