The voltage detection stick comprises an elongate and hollow casing member. A tip is attached to the casing member and has a first leg and a second leg protruding outwardly from the tip. A cavity is defined between the legs. An antenna is disposed within the casing member for sensing a voltage and transmitting a detection signal when an electrically conductive member is disposed in the cavity. An antenna extension is removably attachable within the cavity for increasing the sensitivity of the antenna.
