Ground Microphones and Electronic listening sticks
         Using 
          electronic listen sticks one can confirm the presence of leak noise 
          at pipe fittings. The leak position can be verified audibly by surface 
          sounding prior to the any excavation and repair been carried out. 
        The MK5 
          Ground Microphone combines a new, high sensitivity sensor with proven 
          ease of use, enabling leaks to be detected over a greater distance, 
          and backgound noise to be more easliy suppressed, than with conventional 
          sounding equipment.
        An optional 
          hand-held probe is available for use on fittings or in soft ground conditions. 
          Confirmation of leak location is essential to ensure that excavation 
          is accurately targeted. 
        This speeds 
          up repair of the leak, reduces repair costs and ensures that disruption 
          to the water supply is minimised.
