RD7100 Cable, Pipe
and RF Marker Locator

Industry-specific range of precision locators, each model optimized for a particular utility

vendor P/N: 7100

Radiodetection RD7100 High-Precision Cable and Pipe Locators

RD7100® is Radiodetection’s industry-specific range of underground cable locator equipment featuring advanced locating technologies, including optional foldaway RF Marker Ball antenna, with each model optimized for the challenges of locating a particular buried utility. Integrated GPS and usage logging options automatically generate data for work reports, or in-house quality and safety audits, to promote best working practices.

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 RD7100 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 RD7100 range retains the environmental durability associated with an IP65 rating, meaning you can operate it in almost any environment.

90V Transmitter output

The high voltage output capability drives more locate signal onto high impedance target lines such as twisted pair telecoms cables enabling you to detect utilities deeper and further.

Guidance Mode

This enables the path of a single utility to be found and traced quickly. Directional information is displayed alongside proportional distance arrows to help find the utility and then keep you on its path.

The simultaneous display of depth and current information gives confidence the correct utility is being traced even in congested networks. For rough or uneven terrain differentiated audio tones can free the user to concentrate on potential hazards.

Peak+ Mode – speed combined with accuracy

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.

Automatic usage-logging with GPS positioning

When equipped with GPS, RD7100 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.

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

Optimized precision for your industry

All our RD7100 locators come with Radiodetection’s pioneering features, such as StrikeAlert, Compass Orientation and depth measurement as standard.

Each model of RD7100 also benefits from being optimized for a specific industry:

Construction: RD7100SL

Accurate and simple to use, the RD7100SL comes with four active and two passive frequencies that cover the majority of site locating tasks. A rugged, IP65 rated casing along with a high contrast screen make it suitable for use in all weather conditions.

Water and Pipeline: RD7100DL(M)(G)

With four sonde frequencies, the RD7100DL can be used to trace deep pipes made from a variety of materials including: cast iron, clay, fiber, concrete and brick. Additionally, it can be used to locate Cathodic Protection System (CPS) signals applied to pipelines.

Power: RD7100PL(M)(G)

Designed for use in dense infrastructures where signals from high voltage equipment and cables can be confusing or overwhelming. Dynamic Overload Protection reduces the effect of interference, while Power Filters can be used to establish if a single large power signal comes from one source or from the presence of multiple cables.

Telecom: RD7100TL(M)(G)

RD7100TL features higher frequencies to locate high impedance cables amongst large bundled pairs and sonde frequencies for duct and conduit tracing. Higher frequencies can also be used to trace sheathed domestic cables without grounding connections. Cable sheath faults can be located to within 4” (10cm) using 8kHz Fault Find mode with a Radiodetection A-Frame.

Powerful locating at your fingertips

Interface consistency with our previous locators allows you to transfer knowledge and reduces retraining costs.

Menu options and capabilities are matched to specific industries simplifying use.

RD7100’s ergonomic balanced design and light weight (4.2lbs / 1.9kgs) ensures it is comfortable to use for extended periods.

On-site operator confidence

StrikeAlert™ in active and passive locating modes gives visual and audio warnings of shallow cables reducing the risk of accidents.

TruDepth™ ensures depth readings are only given when RD7100 is correctly oriented ensuring you can be confident in the result.

The integrity of the measurement system can be confirmed on-site.  Self-test applies signals to the locating circuitry as well as checking display and power functions.

ECERT™ allows you to verify and certify the calibration of your locator over the internet using RD Manager PC software package without returning the unit to a service center.

Simplify complex locates

Simultaneous display of depth and current measurements gives you confidence you are following the correct line.

Dynamic Overload Protection filters out interference, enabling use in electrically noisy environments such as near substations or overhead power lines.

Industry specific frequencies and modes simplify menu options and reduce complexity.

Power Filters™ uses the harmonic properties of mains networks to establish if a strong power signal comes from one source of multiple cables.
