The Zapper allows players to aim at the television set display and “shoot” various objects that appear on the screen such as ducks, clay pigeons, targets, cowboys, criminals or other objectives. The Zapper is used on supported NES games, such as Duck Hunt and Wild Gunman. The Zapper could also be used on the title screens of games to move the cursor—done by pointing the device away from the screen and pulling the trigger—or starting the game (pointing at the screen and pulling the trigger).
*** Be carefull, these zappers only work on old CRT type screens. Not on LCD, LED or any other newfangled type of image screen ***
