The Model 2000 Play Clock controller allows the Model 1000 display unit to be wirelessly controlled as a play clock from the game field or practice field. The unit can be conveniently belt clipped (see picture below) and is controlled with a single button. Simply press the button to start the clock, press again to stop, press again to reset to 25 seconds and press again to start. A version is available to accommodate the 40 second play clock operation used at the college and professional level. A charger is provided for charging the internal battery pack.
