The Fisher XLT-30 is built for professional leak detection specialists who require precision and reliability in the field. Designed to pick up the faintest sounds of underground leaks, the XLT-30 stands out with its advanced filtering system and crystal-clear audio clarity. Whether working on concrete, asphalt, or turf, the XLT-30 adapts to your environment with sensor options tailored to specific site conditions.

Equipped with high-sensitivity microphones and a non-distortion amplification system, the XLT-30 delivers exceptional audio feedback for pinpointing leaks. The unit includes selectable filters (All Pass, Low Pass, High Pass, Band Pass, and Notch) with adjustable frequency ranges to isolate leak sounds from background noise. Visual feedback is provided through an LCD bar graph and digital readout, while the notch filter helps reject interference from nearby motors or traffic. The optional Multi-Sensor enables detection on both hard and soft surfaces, simplifying fieldwork without compromising performance.

Engineered for demanding jobs, the XLT-30 features a rugged splash-proof housing, intuitive controls, and lightweight portability. The ergonomic design includes an adjustable neck strap, padded headphones, and sound rods for direct contact use. Powered by two 9V batteries, it delivers up to 50 hours of operation—ideal for long shifts without interruption. Designed and assembled in the USA, the XLT-30 is a durable, field-proven tool trusted by leak detection professionals worldwide.
