Fisher XLT-30 manual Instrument SET, Control Box, Big Foot Probe, Hydrophonic Cylinder Probe

INSTRUMENT SET

1. Control Box

All listening and filtering controls for the XLT-30 are contained in this sturdy housing. The function of each control is described in the section entitled “Faceplate and Controls”.

2. Big Foot Probe

Also known as the Ground Microphone, this probe is to be used on hard surfaces, concrete, asphalt, tile, etc. A flexible rubber shield helps prevent outside sounds from interfering with the sounds from the buried pipe. De- pressing the red button near the handle will Mute the audio from the probe to suppress loud sounds when the probe is moved.

3. Hydrophonic Cylinder Probe

This probe is a direct contact probe designed to make direct connection to the pipe, or any portion of the pipe that is accessible. Used in any combina- tion of Sound Rods with the T-Handle, pipes can be accessed to distances up to nearly 6 feet away.

Another feature of the Cylinder Probe is the ability to listen to pipe noise in pipes that are buried in turf, or soft surfaces. Accurate pipe location is essential for the placement of the Ground Rods as close to the pipe as pos- sible.
