TEMPO Communications 501 Tracker II Cable Locator

TEMPO Communications 501 Tracker II Cable Locator

Key Takeaways:

  • Traces active/dead systems without deactivation
  • Transmitter range up to 4,000 feet
  • Fully adjustable for maximum accuracy
  • Lightweight and durable construction
  • Dial setting instructions could be clearer

The TEMPO Communications 501 Tracker II Cable Locator is a formidable tool for anyone in the business of underground cable and pipe locating. We like its ability to trace the path and determine the depth of buried wires and metallic pipes. Impressively, this can be done on both active and dead systems, eliminating the inconvenience of system deactivation. This model is notably lightweight, tipping the scales at just 6.7 pounds.


With dimensions of 33.50 x 8.250 x 3.750 inches, it’s a reasonably compact piece of equipment, easy to carry and maneuver. Its construction speaks to its durability, with the transmitter and receiver crafted from powder-coated aluminum and a case made of vacuum-formed polyethylene.

The transmitter hits high marks with a robust range of up to 4,000 feet and a depth reach of 7 feet. Such stats don’t just look good on paper; they translate to reliable cable or pipe detection, even when they’re tucked away under concrete and carpet.


Another notable feature lies in the transmitter’s trio of connection methods: direct, inductive coupler, and inductive antenna. Our field tests confirmed the practical value of this versatility. Switch over to the receiver, and you’ll find both audio and visual indicators for signal strength.

This dual feedback system comes in handy when you’re working in a loud setting or require surgical precision. Want to dial in the settings to your liking? Both transmitter output and receiver sensitivity are fully adjustable, allowing you to fine-tune your locator to match the task at hand.


One minor gripe is that the instructions for setting the dial could be clearer. But once you’re accustomed to its function, it proves to be a time-saver. For those worried about battery consumption, there’s an automatic shut-off after 90 minutes on both the transmitter and receiver. Given the battery life – 30 hours nominal for the transmitter and 10 hours for the receiver – this device can last through extended jobs.

RIDGID 19238 NaviTrack Scout Locator

Underground utilities are nothing short of a maze, and trying to successfully and safely navigate them can be challenging. Enter the RIDGID 19238 NaviTrack Scout Locator, a compact tool with the capability to unravel these underground mysteries.


For professionals in fields such as plumbing or septic, this device is an indispensable ally. Built from Acrylonitrile Butadiene Styrene (ABS), it possesses a ruggedness suited for both indoor and outdoor use, colored in an easy-to-spot red and black combination.

With a weight of just 3 pounds, it’s light enough to be handled with ease yet substantial enough to feel like a solid piece of equipment in your hands. Powered by 4 C-cell batteries, you can expect between 12 and 24 hours of operation, although the duration does vary based on factors like battery rating and usage intensity.


Alternatively, for those who’d prefer a rechargeable option, there’s an adaptor available for the RIDGID Professional 18V battery, adding versatility to its power sources.

As we tested this unit, it became clear that the multi-directional technology is an invaluable addition. Its antenna constantly observes the entire signal from all angles. This means locating that elusive underground pipe or wire becomes less about guesswork and more about precision.

As the signal strength rises, you’re zeroing in on your target, minimizing instances of false peaks or nulls. Couple that with its superior speed and accuracy, and you have a tool that not only locates but also provides real-time signal strength readings.

Furthermore, its micro-mapping feature offers a visual representation of the target area, coupled with on-screen markers and automated depth calculations, ensuring efficient and accurate locates.


To further its user-friendly appeal, the NaviTrack Scout Locator comes in an all-in-one package. A carrying case ensures it remains protected while on the move, while included extras like surface marker chips and an instructional video make for a more comprehensive experience.
