Radiodetection RD8100

Engineered to deliver high precision for damage prevention when locating buried cables and pipes.

RD8100, our most advanced precision locator range for sale, is built on this pedigree for performance, quality and durability. Containing a unique arrangement of 5 antennas, it allows you to choose the optimum level of precision for the job in hand. Integrated GPS and usage-logging options automatically generate data for customer reports, or in-house quality and safety audits to promote best working practices.

Making complex locates simpler

With utility infrastructures becoming more complex, locate professionals require more powerful tools to simplify the task of distinguishing between and tracing different utilities.

CD (Current Direction)

Identify your target amongst a number of parallel utilities by applying a specialized CD signal from the Tx-10 transmitter. CD arrows displayed on the locator confirm you are tracing your target.

Trace high-impedance utilities with 4 kHz

The 4 kHz locate frequency enables lines such as twisted pair telecoms or street lighting to be traced over longer distances. Since such utilities are often found in areas of dense infrastructure, you can combine 4 kHz with CD to improve trace accuracy.

Use Power Filters™ to pinpoint and discriminate between power cables

When a signal transmitter can’t be connected, tracing individual power lines through dense networks can be a real challenge. Conflicting or powerful signals confuse or combine to create a wash of signal.

A single key press uses the harmonic properties of power signals to establish if a signal comes from one source, or from multiple cables which you can then trace and mark.

Speed combined with accuracy – Peak+ Mode

Peak+ mode allows you to add either Guidance or Null locating to the accuracy of Peak mode.

  • Adding Guidance gets you to the Peak position faster.
  • Adding Null to Peak lets you check for the distortion caused by other utilities, spurs SideStep™ or interference.

Supporting your business

Every locating operation needs to meet the continuing challenges of delivering on-time, high quality work and

increasing value to customers.

Automatic usage -logging with GPS positioning

When equipped with GPS, RD8100 locators automatically capture key locate parameters every second, providing a comprehensive picture of individual locates and allowing you to assess usage patterns over extended periods.

The data generated can be used to ensure adherence to best-practice, or to identify training needs before poor work habits develop.

Additionally, the information can be used for internal audits or shared with partners or clients to evidence task completion, or compliance to service requirements.

Usage data can be exported in multiple file formats – for example KML for Google Maps to confirm where and when work was performed.

eCer t™ – Remote calibration without downtime

Verify and certify the calibration of your locator over the internet using the RD Manager™ PC software package without returning the unit to a service center. Have confidence that the RD8100 is ready for action whenever you are.


Choose to automatically enforce maintenance or lease schedules by providing a 30 day countdown before the calibration certificate expires.

Support when you need it

The RD8100 is backed with an industry leading 3 year warranty on registration. Our global sales and service network delivers comprehensive technical support and training tailored to your needs.


Getting more from your RD8100 system

Customize the locator to your network frequencies

Up to 5 additional frequencies can be programmed into all RD8100 locators to match it to the signals found on your target telecoms networks.

Accurate surveying with integrated or external GPS

Save up to 1,000 survey measurements, capturing utility depth, and send to a mobile device using Bluetooth. Add positional data with the integrated GPS option, or combine with external GNSS device using the wireless Bluetooth link to get the accuracy that you need.

Fault Find

Combine the RD8100 locator with an accessory A-frame to identify and pinpoint insulation sheath faults to within 4" (10cm).

RD Manager PC software

Set-up, calibrate and update your locator from a PC. Download usage logging and survey measurement data for analysis.

Passive Avoidance

Rapidly check an area before excavation using simultaneous detection of the Passive Power and Radio signals carried on underground cables or pipes.

90V Transmitter output

More locate signal on high impedance target lines – detect deeper and further.

Multimeter function

Assess the target utility using your transmitter – quickly measure line voltage, current and impedance.
