Overview
The RD5100 Pipe Locators series is designed to handle problems where pipes have a rubber seal, insulators or gaps between sections. The 83kHz of the RD5100H2O is great for locating disjointed pipes and cables as well as plastic pipes with a tracer wire. This signal is more likely to penetrate the gap of broken trace wire and other discontinuities and still impose signal on the downstream side of the conductor.
The RD5100 series of locators are lightweight, easy to use, and have a large, clear, easy to read display screen. The screen is well designed with pertinent information such as guidance arrows, compass, and signal strength helping the locating operator to hone in on the target. These features plus some additional ones are standard on the locators in this series.
Guidance mode:
- Target position indicator
- Left/right arrow adjustments to keep you on target
- Audio tones (continuous or intermittent) that provide guidance to keep you on target
- Compass a visual indication of pipe or cable orientation


Additional Standard Features:
- TruDepth provides the depth of the cable or pipe when the RD5100 is correctly oriented above it.
- Dynamic Overload Protection filters out interference enabling it to be used in electrically noisy environments.
- Depth and Current information is provided to so you know you are following the correct target.
The Radiodetection RD5100H2O has a Power passive frequency that takes advantage of signals that are already present on buried metallic conductors. Power frequencies may be detected without the aid of a transmitter. In addition, the RD1500H2O receiver can also be used with the RD5100 Transmitter 10/51H2OTX-US. If using the transmitter, you can locate pipes by either a direct connection or induction.
A great additional feature for the RD5100H2O is that it comes standard with rechargeable Li-ion batteries that extend the operating time and reduce the cost of purchasing additional batteries.
The RD5100H2O locator can be purchase separately or as part of the kit 10/51H2OI60-KIT which includes the 5100H2O Locator and Transmitter, Li-ion battery packs, earth stake, direct connection lead, and soft bag.
