The arms (3) having first ends (5) to be gripped by a user and second ends (6) having contact surfaces (10) to engage an object. The sensing means (9) operatively associated with said contact surfaces (10). Alarm means (15, 20, 23) operatively associated with the sensing means, (9). The alarm means (15, 20, 23) are adapted to alert a user when a voltage is sensed by said sensing means (9).
