<p>The voltage detection stick (10) comprises an elongate and hollow casing member (12). A tip (16, 204) is attached to the casing member and has a first leg (206) and a second leg (208) protruding outwardly from the tip. A cavity (212) is defined between the legs. An antenna (70, 260) is disposed within the casing member for sensing a voltage and transmitting a detection signal when an electrically conductive member (225, 261) is disposed in the cavity. An antenna extension (220) is removably attachable within the cavity (212) for increasing the sensitivity of the antenna (260).</p> |
