PROFESSIONAL-GRADE UTILITY LOCATOR – Locate underground electrical lines, telecom cables, irrigation wires, and metallic pipes with precision over 1 mile (1.6 km) and depths up to 20 feet (6 m) with the 551 underground wire locator. DUAL FREQUENCIES + INTELLITRACK NOISE REJECTION – Simultaneously transmit two frequencies and eliminate AC interference with proprietary IntelliTrack digital filtering for accurate readings in noisy environments with the 551 cable locator. PEAK & NULL RECEIVER MODES – Choose between peak or null response to fine-tune your search and detect anomalies with confidence, even in complex underground environments with 551 buried wire locator. FLEXIBLE CONNECTION OPTIONS – Use direct wire connection , inductive clamp, or built-in antenna on 551 wire locator for maximum adaptability on active or inactive systems. BUILT FOR THE FIELD – Rugged, IP54-rated, and ergonomically designed with a lightweight receiver and durable case for reliable use in demanding job sites. Introducing the Tempo 551 Advanced Underground Locator – the Professional Grade, All-in-One Location Solution. Designed for professionals and packed with advanced features, the 551 utility locator brings you everything you want in a Locator including; dual simultaneous frequencies, Peak & Null receiver, and IntelliTrack digital noise rejection. The proprietary IntelliTrack digital noise rejection technology offers signal clarity in noisy environments to give you an effortless locating experience that’s smarter, faster, and more accurate. Connect to any type of wire, use our inductive clamp or transmitter antenna when a direct connection is not available. You can also choose between peak/null modes or between two simultaneous frequencies while in the field, always ensuring optimal signal performance and enabling side-by-side comparison to better detect and characterize anomalies. And if you often locate near AC lines or change transmitter frequencies the 551 Advanced Locator offers IntelliTrack digital noise rejection technology, so you can reliably trace lines near power sources. If AC interference is an issue, the 551 will give you two unique options for tracing without needing to walk back to the transmitter. Select Passive Mode to detect the source of the noise. Whether you’re tracing electrical lines, irrigation wires, telecom cables, or metal pipes, this rugged, IP54-rated locator is built for performance. The 551 can locate and trace utilities over 20 feet deep (6 m) and over 1 mile (1.6 km) in distance. With an ergonomic, lightweight receiver and a rugged case, the 551 delivers reliability, efficiency, and ease of use at an affordable price.
