Below are some pictures of the equipment to
familiarize you with what they look like and how they work.
This is an actual picture of the FC 4000 Field Instrument and the
sonde. The sonde along with the wire attached to it are pushed
into the subsurface using the Geoprobe. The nodes on the sonde
send the current into the lithology, which in turn sends a signal to the
Field Instrument for a conductivity read-out.
This picture is showing the controls to the Geoprobe. Use of
this instrument takes practice. The levers along the bottom of the
instrument control the tilt and the forward and backward motion of the
Geoprobe. It is always important to make sure the system is level
before drilling. The top, right lever controls the hammer if
needed. This is only necessary if you are drilling into rock,
gravel, etc.
This is a photo displaying the rack that holds the EC pipe. The
conductivity wire is strung through the pipe so the Geoprobe can push
them underground. A rack contains 16 pipes, each of which are 4ft.
long.
