Radiodetection’s RD7000+ Underground Utility Locator range delivers accurate, reliable and repeatable performance in an easy-to-use digital package.

Locating specific pipes, cables and utility RF markers in large underground networks is very complex. Ground distortion effects, caused by differing soil types and proximity to other conductors, make the user’s job more difficult and time-consuming. The most important requirements for a locator under these circumstances are ease of use, accuracy and reliability. Radiodetection’s RD7000+ Utility Locator range addresses these needs with many features that deliver accurate, reliable and repeatable performance. The new RD7000+ marker locators – denoted ‘M’ add RF marker locating to the range, with automatic marker depth estimation and Bluetooth® connectivity as standard


Light weight – at only 4.2lbs / 1.9kg or 5lbs / 2.3Kg, for marker models the RD7000+ range is comfortable to use for extended periods.
IP54 protection rating – can operate in almost any environment. High contrast backlit LCD screens on both transmitter and locator allow use in any light conditions.

RF utility marker locator with automatic depth estimation

Radiodetection’s unique automatic marker depth estimation provides measurements when the locator is in 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 cable, pipes and RF markers reducing survey time. RD7000+ marker locator models detect all commonly used RF utilities markers enabling use across multiple industries. 


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

Proportional Left–Right Arrows

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

Extends the RD7000+’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 such as power sub stations or near overhead high-voltage cables.

Bluetooth Connectivity (marker models)

RD7000+ marker locator models offer Bluetooth connectivity as standard. This allows the locators to interface to external devices for easy transfer of survey data directly into maps and databases.

Automatic data logging and CALSafe (PLM and TLM models)

PLM and TLM models feature integral logging systems. It records up to 1 year’s typical usage of significant locate parameters every second
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. These locators also 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.


Three models capable 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 model features 8kHz Fault Find functionality; TX-10 models feature both 8kHz Fault Find and Current Direction (CD functions require use of RD8000 locator) functions. 90V output capability: All transmitters offer both 30V and 90V 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

Using the Windows compatible supporting software, locators can be checked for correct calibration and operation over the internet
using eCERT™ (for marker models) or eCALTM (for non marker models) calibration validation service, without needing to return the RD7000+ to a service center. Operators can then print, email or save a calibration certificate, or book a service should any issues be detected.
