RD8100, our most advanced precision locator range, is built on a pedigree for performance, quality and durability. The unique arrangement of 7 antennas allows you to optimize your RD8100 for different tasks with each mode using a different combination of antennas.

At the heart of each of our locating antennas is a custom-manufactured, precision-ground ferrite to ensure the accuracy and precision of your measurements.

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.

On-site operator confidence

  • Interface consistency with our previous locators allows you to transfer knowledge and reduces retraining costs.
  • 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.
  • Power Filters™ uses the harmonic properties of mains networks to establish if a strong power signal comes from one source of multiple cables.
  • 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 RD8100 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.

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.

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.

Product Details

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 Impedence 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. 

Guidance Mode allows you to quickly follow utility paths
Guidance Mode allows you to rapidly find and follow the path of a buried utility. 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 be used, freeing the user to concentrate on potential hazards. 

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  or interference.

Customise 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.

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

Choose the optimum mode for your locate
Our unique arrangement of 5 antennas allows you to optimize your RD8100 for different tasks. Each mode uses a different combination of antennas. At the heart of each of our locating antennas is a custom manufactured, precision-ground ferrite to ensure the accuracy and precision of our measurements.

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. 

Li-Ion rechargeable battery options
Lithium-Ion rechargeable battery options for both locator and transmitter provide extended runtime with reduced running costs.
