The RD8100 improves on speed, accuracy and reliability yet remains a cost-effective solution delivering unique user features. Powered by a digital architecture , RD8100 delivers a highly controllable and reliable locate solution to service any industry, anywhere in the world.

Ergonomics Ergonomics

  • Light weight – at only 4.2Ibs, 1.9 kg or 5lbs/2.3Kg, for marker models, the RD8100 range is comfortable to use for extended periods.
  • IP54 protection rating – can operate in almost any environment
  • Transmitter and locator feature a large, high contrast backlit LCD screen.


  • Combination of new and innovative algorithms with established software on a high-performance processor core
  • Improves the accuracy and repeatability of measurements
  • Delivers powerful signal filtering and analysis allowing continued operation even in the most electrically noisy environments

RF utility marker
RF utility marker
RF utility marker locator range with automatic depth estimation

  • Radiodetection's unique automatic marker depth estimation provides measurements when the locator is close proximity of the marker, without requiring a manual two step 'lift up' process thus providing more accurate results.
  • Combined mode allows users to simultaneously scan for cables, pipes and RF markers reducing surveying time.
  • RD8100 marker locator models detect commonly used RF utilities markers enabling use across multiple industries.


  • iLOC is an advanced Bluetooth® link between the RD8100 locator and transmitter
  • iLOC allows the operator to control the transmitter remotely
  • Less time walking and more time locating.

SurveyCERT™ SurveyCERT™

  • Gives the operator the tools to pass survey information to third-party applications for audit, analysis and reporting
  • 1000 locate records can be stored and reviewed
  • Upload this information to PDA or PC using RD8100 Bluetooth connection.


Depth readings are only indicated when the locator is correctly oriented above the target pipe, cable or sonde or in close proximity to a marker. Unique automatic marker depth estimation provides measurements without requiring a manual two-step 'lift up' process, delivering faster and more accurate surveys.


  • Visually indicates orientation of the target cables.
  • Allows the operator to quickly and easily follow the target line.
  • Maximizes depth measurement accuracy by ensuring the locator is correctly with the target line.

Proportional Left - Right Arrow
Proportional Left - Right Arrow

  • Visually indicates orientation of the target cable.
  • Guides the user to the central axis of the pipe or cable with dynamic left/right arrows, enhanced with differentiating sound.
  • Distance from target cable indicated by length of arrow.

Dynamic Overload Protection
Dynamic Overload Protection

  • Extends the RD8100's locate capability into areas where other products fail.
  • Automatically filters out large and unwanted signals while ensuring accurate location of the target pipe or cable.
  • Particularly useful in electrically noisy environments surch as power sub stations or near overhead high-voltage cables.

Bluetooth® Connectivity and GPS
Bluetooth® Connectivity and GPS

  • Bluetooth connectivity as standard. This allows the locators to interface to external devices for easy transfer of survey data directly into maps and databases.
  • Optional integrated GPS option for RD8100 models, which enables association of survey data with positional data without the need to carry external equipment. The RD Manager PC software allows easy transfer of the locator's survey data directly into common file formats such as KML for Google Earth.


Three models cable of delivering up to 10W of true output power, maintaining constant current across their entire bandwidth in direct connect, clamp or inductive modes to enable fast and repeatable surveys.

  • Tx-5 models feature 8kHZ Fault Find functionality; Tx-10 models feature both 8kHZ Fault Find and Current Direction functions.
  • Tx-5 and Tx-10B models support iLOC functionality which enables remote control features simplying operation and reducing surveyting time.
  • Tx-10B fully supports the extended range of the RD8100 PTLM locator to targe telecom and power industries.
  • 90V output capability: All transmitters offer both 30V output options, resulting in higher signal current delivered on high impedance target lines than typical transmitters that only offer a 50V output. Higher signals are more locatable signals that travel a longer distance.
  • SideStepauto: allows the transmitter to calculate the optimum frequency based on ground impedance. The transmitter uses this information to optimize the active frequency. Sidestepauto helps to improve locate accuracy and extends battery life.
  • ECO mode: extends alkaline battery life by warning the operator and gradually reducing the power output in low battery condition ( Tx-5 and Tx-10 models only).

Remote Calibration
Remote Calibration

  • Using the Windows® compatible supporting software, locators can be checked for correct calibration and operation over the internet using eCERT™ ( for marker models) or eCAL ( for non-marker models ) calibration validation service, without needing to return the RD8100 to a service center. Operations can then print, email or save a calibration certificate, or book a service should any issues be detected.
  • eCAL can issue and print validation certificate without needing to return the RD8100 to a service center.

Automatic data logging and CALSafe™

  • Optional integral logging systems for marker models. It records up to 1 year's typical usage of significant locate parameters every second (including positional data for RD8100 GPS models) and helps identifying training and development needs, and provides independent historical records of the instrument's use. Backed-up data on a PC gives virtually unlimited record keeping for the life of the product.
  • All marker locator units that feature data logging or GPS provide a convenient 30-day service countdown reminder. CALSafe, a user selectable tool, can be enabled to enforce a recall for service and calibration by disabling the unit after this date.

Centros Manager
Supporting Software

The RD8100 range of locators and transmitters are supported by two application suites for Microsoft® Windows®: Centros Manager for standard cable and pipe locators and RD Manager for marker locators.

Rechargeable battery packs
Rechargeable battery packs for Locators and Transmitters

  • Available for Precision Cable and Pipe Locators and the Tx Transmitter range. Standard for all Marker Locator Models.
  • Offer increased flexibility.
  • Provide improved cost-of-ownership.
  • Deliver excellent run-time and superior cold-weather performance by comparison to standard alkaline batteries.
  • No need for operators to replace, manage and recycle alkaline battery cells, reducing the associated costs, workload and environmental burden.
  • Locator rechargeable battery packs are supplied with a mains charger (90V to 240V,50/60Hz) as standard. An automotive charger (12V to 24V DC) is also available for use on the move.
  • Transmitter rechargeable packs are available in kits that include the rechargeable battery pack, a mains charger (90V to 240V, 50/60Hz) and an automotive charger (12V to 24V DC).
  • Individual chargers and battery packs are also available as separate parts for both locators and transmitters.
