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 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.

Take your underground locating and safe digging to the next level—experience the 551 today!

Features
• Dual Simultaneous Frequencies

By default, the 551™ Transmitter sends out two frequencies simultaneously ensuring optimal signal performance and enabling side-by-side comparison to better detect and characterize anomalies - all while in the field.

• IntelliTrack™ Noise Rejection

With IntelliTrack™, we added digital noise rejection in our Receiver so that you can clearly track cables carrying a signal, despite electrical interference.

• Inductive Clamp

With the IC-5 clamp, this locator can apply a signal without needing to disconnect or de-energize the line.

• Transmitter Induction

Place the 551 Transmitter in Inductive Mode a few feet over a line and emit a long-range, low-bleed signal.

• Passive

Detect andd trace power lines carrying live AC-current without using the Transmitter.

• Peak/Null

Now you don’t have to choose, you have both in the same locator. Track the line with Peak and pinpoint with Null in any frequency.

• IP54

Protected with IP54-rated resistance to water and debris means the 551 can withstand conditions on any job site.

• Bright LCD

1,000-nit LCD display makes the screens easy to read in any lighting conditions.
