Fisher 203-655-60-00 Big Foot Ground Microphone Assembly for XLT30 Leak Detector

High-Sensitivity Ground Microphone for Hard Surface Leak Detection

• Designed specifically for Fisher XLT30 leak detector systems
• Ultra-sensitive ground microphone for detecting acoustic leak signals
• Flexible rubber shield helps isolate external noise and wind interference
• Large sensor base improves surface contact on concrete, asphalt, and tile
• Integrated mute button suppresses noise when repositioning the sensor

Acoustic Isolation Design for Precise Leak Pinpointing

The Big Foot sensor assembly uses a large shielded base and acoustic isolation design to capture vibration and sound produced by leaking underground pipes. When paired with the XLT30 control unit, the sensor enables operators to clearly distinguish leak signals from surrounding environmental noise during field inspections.

Typical Deployment Environments

• Municipal water distribution leak detection
• Underground pipeline inspection beneath pavement
• Utility maintenance on asphalt, concrete, and tile surfaces
