PARABOLIC PINPOINTER

The Model 251 Ultrasonic Detector delivers industry-leading precision for detecting arcing and corona on energized overhead power lines. This rugged, all-in-one unit combines an 18-inch clear parabolic reflector with an integrated ultrasonic sensor and receiver, allowing field crews to quickly and accurately pinpoint electrical faults from the ground or bucket truck. Advanced directional sensitivity cut through ambient interference, providing fast, reliable identification of problem hardware.

Operators simply aim through the built-in sight, monitor the signal strength meter, and confirm faults with clear audible feedback for confident visual and audio verification. Designed to complement Radar Engineers’ RF-based locators, the Model 251 adds ultrasonic line-of-sight precision to your diagnostic toolkit, making it an essential instrument for utility professionals seeking faster and more certain power line diagnostics.
