  • Game call
    Patent number: 4888903
    Abstract: A reed-type game call which can be operated by blowing and sucking on a single end of the call. This permits a caller to make one type of sound when blowing out through the call, and a different or same sound when sucking in, thus allowing for rapid sound successions. This permits the caller to sound like a whole flock of geese, or ducks with the rapid varied sound; it also permits a hyperventilating deer sound.
