Product Description

The Fisher XLT-17 is engineered for utility professionals and leak detection specialists who require precision and performance in the field. Equipped with Fisher’s advanced Multi-Sensor technology, it delivers exceptional audio clarity for identifying leaks under various surface types—from asphalt and concrete to turf and soil.


The XLT-17 features four adjustable audio filters (All Pass, Low Pass, High Pass, and Band Pass) that enhance sound detection depending on pipe material and ground conditions. Its ultra-sensitive Multi-Sensor picks up subtle vibrations caused by pressurized leaks, while the high-performance headphones and visual LCD display ensure accurate, real-time feedback. With intuitive controls, frequency customization, and plug-and-play operation, the XLT-17 is a powerful and adaptable tool for pinpointing difficult-to-detect leaks.


Built for long days in the field, the XLT-17 is housed in a splash-proof control unit and includes a durable mounting strap for hands-free operation. Weighing just 10 lbs and running up to 50 hours on two 9V batteries, it offers lasting performance without sacrificing comfort. Whether working on paved streets or soft ground, the rugged design and ergonomic accessories make the XLT-17 a reliable choice for professional leak detection.

Frequently Asked Questions

What filter mode should I use for initial leak detection on unknown pipe types?

Start with the All Pass (AL) filter mode, which spans 60 Hz to 6 kHz. This provides a full-spectrum audio response, ideal for locating the general area of a leak before switching to more focused filter settings.

How does the Multi-Sensor handle background noise on hard surfaces like concrete or asphalt?

The Multi-Sensor features a rubber housing diaphragm specifically designed to dampen environmental noise. This isolates leak-generated vibrations while minimizing interference from surface contact.

Can the XLT-17 detect leaks under soft ground or turf?

Yes. Attach the included T-handle and sound rods to the Multi-Sensor for direct ground penetration. This configuration increases sensitivity and helps transmit leak vibrations through loose soil or grass-covered areas.

How do I fine-tune the filter settings for a leak with minimal acoustic signal?

Use the HI, LO, or FC filters and adjust the frequency range with the arrow keys. The Frequency Choice (FC) mode is particularly useful for isolating narrow frequency bands where weak leak sounds may be more audible.

What’s the difference between Low Pass and High Pass filter modes on the XLT-17?

Low Pass allows low-frequency sounds (like deep water leaks) while filtering out high-frequency noise. High Pass does the opposite, enhancing high-frequency sounds, which are more common in shallow or pressurized leaks.

How can I tell if the XLT-17’s battery is running low during use?

The XLT-17 includes an automatic, real-time battery indicator. A battery reading under 5V will activate the “Low Battery” warning, giving you time to finish your task before shutdown.

Does the XLT-17 store filter and volume settings between uses?

Yes. All active settings — including volume and filter configurations — are saved in memory when powered off and will automatically reload upon the next startup.

What type of audio output is best for evaluating leak severity?

The XLT-17 uses high-impedance (64 ohm) headphones to deliver clear, distortion-free audio. Leak severity is typically judged by sound intensity and frequency consistency over time.

Is the XLT-17 suitable for use in wet or rainy environments?

The control unit is splash proof, making it suitable for damp environments. However, it is not rated for full water immersion, so precautions should be taken in heavy rain.

Can I use the XLT-17 with other sensor types or accessories?

The XLT-17 is optimized for use with its proprietary Multi-Sensor and sound rods. While other accessories are not officially supported, compatibility depends on matching connector specs and electrical requirements.
