INTRODUCTION
Fisher Research Laboratory has always been a leader in the field of acoustical leak detection. From the early LT-10 through the XLT-20, high quality sound amplification has been synonymous with the name Fisher.
Fishers XLT-30 takes leak detection to a new level. Ultra sensitive sound microphones, combined with a non-distortion amplification system and crystal clear audio headphones make the XLT-30 the leak detector destined to set new standards for the leak professional.

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. Depressing 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 combination 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 possible.
