RD8100 Cable, Pipe
and RF Marker Locator

Optimum precision, performance, quality and durability built for damage prevention

vendor P/N: 8100

Radiodetection RD8100 Series Locator

RD8100 is Radiodetection’s most advanced precision locator range, built for performance, quality and durability. Containing a unique arrangement of 7 custom-manufactured, precision-ground antennas, it allows you to choose the best method to locate specific pipes and cables plus the optional foldaway RF Marker Ball antenna allows you to choose the optimum level of precision and speed for any job.

With utility infrastructures becoming more complex, locate professionals require more powerful, flexible tools. Features such as Current Direction and iLOC™ on the cable locator combine with the versatile Tx Transmitter range to deliver high-precision locates even in tough conditions.

Integrated GPS and usage-logging options automatically generate data for customer reports, or in-house quality and safety audits to promote best working practices. The RD Map app for Android is a real time map and share tool that creates maps of buried utilities, while the RD Manager PC program provides a suite of useful tools to the user.

Making complex locates simpler

Combined line and marker location mode

All the RF marker locators offer both a combined utility and marker locating mode as well as automatic marker depth measurement, eliminating the typical 2 step manual process. Consistency of depth and current measurements gives you confidence the correct line is being followed.

View your survey points on Google Maps

Use RD Map™ to create, in real time, detailed maps of buried utilities. Survey measurement data is added to location coordinates information to map the route of the tracked utility. Map files (CSV or KML) can then be shared with customers and colleagues.

The RD8100 is ergonomically designed to deliver a superior performing locator that provides the user with a light weight, energy efficient, exceptionally well balanced tool which is comfortable for extended periods of use.

Despite its weight and form, the RD8100 range retains the environmental durability associated with an IP65 rating, meaning you can operate it in almost any environment.

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 lets you check for the distortion caused by other utilities, spurs or interference.

Achieving more with your RD8100 system

Simultaneous marker and line locating

For rapid utility detection RD8100 marker locators enable operators to scan for pipes, cables and RF markers at the same time, speeding up locate tasks and minimizing missed locates.

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.

RD Map for Android

Create detailed KML utility maps in real time* and share them directly from the field using the free RD Map android app. Use Google Maps technology to review and correct any errors and produce professional maps that can be e-mailed or shared using a compatible app.

*Requires data connectivity. RD Map only works in countries where Google Maps is available.

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.


iLOC is an advanced Bluetooth link between the RD8100 locator and Bluetooth enabled transmitter, which allows you to control the locate signal’s power and frequency from up to 1400’ / 450m away. Spend less time walking and more time locating.

Multimeter function

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