Radiodetection RD7100 Pipe and Cable Locator Features

The new RD7100 underground utility locators optimizes locating with models for water / sewer, power / electric, communications / telephone and contractors.

  • New Easy Guidance Mode: RD8100 / RD7100 Guidance Mode video
    1. The blank area in the bar across the top of the display represents the location of the utility. Just move towards the blank area until it's centered.
    2. Left ]\ right arrows easily guide you to the center
    3. A continuous tone on the left or a pulsing tone on the right, quiet in the center simply guide the user to the center. 
    4. A large line in center of the display stays parallel to the utility showing the direction of the utility.
    5. Automatic gain control (no adjustments needed)
  • Internal GPS & Usage Data Storage: Save 1000 location with a single button push each for the easiest way to improve GIS utility maps. Stores usage data every second for over 5 years for training and documentation.  (optional)
  • Precision Antennas: Ferrite core antennas diamond precision ground to 0.01" and aligned to 0.1 degree and secured for long term accuracy.
  • Clearly Displays Utility Orientation with a line that stays parallel with the pipe or cable.
  • Automatically Displays the Depth only when aligned and nearby the utility to prevent errors.
  • High-Performance Processor Core runs new innovative algorithms: Over 50 software and hardware patents improve the accuracy and repeatability of measurements with powerful signal filtering and analysis even in the most electrically noisy environments for better underground utility locator performance to locate pipes and cables.
  • On-site Calibration Check:  Plug in a standard USB cable and check the calibration of your RD8100, RD8000, RD7100, RD7000 or RD5000 utility locator from your office.
  • Dynamic Overload Protection: Filters out unwanted signals in places like substations and overhead railway high voltage cables that overloads other locators.
  • Arrows quickly guide the utility locator operator to the center of the pipe or cable with left and right arrows that are longer when the utility locator is farther from the target pipe or cable and a variable tone that is different on each side for quicker and easier locating.
  • Active Power Cable Warning: Alerts the locator operator of shallow power cables with an alarm tone.
  • Light weight: 28% lighter than industry standard RD4000 utility locator.
  • Balanced: The balanced design promotes accurate vertical alignment while locating and minimizes wrist strain.
  • Improved Display: Large, high contrast automatic backlit LCD screen on both the transmitter and receiver.

  • 3 Battery Choices: Rechargeable Li-ion quick change battery door, two nickel metal hydride rechargeable or alkaline 2-D cell batteries with a life of 30 hours.
  • Peak and Null Antennas:  Compare the peak to the null to determine the locate accuracy.
  • 3 Year Warranty when registered for free
  • USB Port for firmware upgrades without sending it.
  • Saves all settings when powered down
  • Withstands Water Jets from any direction and the highest level of dust protection - (IP65)
