5. The Ground Microphone/Geophone
To assemble the Geophone, take the T-bar handle and screw into the
stainless steel plate of the Geophone base in a clockwise direction.
There should be no thread visible once complete. When attaching the
cable ensure the notch lines up between the 4 way plug on the cable
and the socket of the T-Bar.

5.2 Techniques using the Geophone
Use the Geophone to surface sound and pin point on compact earth,
concrete and tarmac. When sounding on grass use a hand-probe or a
piece of plywood to act as a sounding board, this will help to reduce the
tickling sound caused by the blades of grass on the Geophone sensor.
