RD312 is a simple, reliable metal locator for finding buried valve box covers, vault covers, fuel tanks, rebar, manhole covers and other metal objects that slow down site work.
RD312 is designed for crews who need fast answers without a complicated locating workflow. It automatically adjusts to the local environment, ignores smaller nuisance metal and gives a clear audio response when a target object is detected.
The RD312 focuses on simplicity and reliability. Its two-button controls, automatic sensitivity adjustment and variable audio tone make it a strong choice when the target is a buried cover, valve or metallic object rather than a cable or pipe route.
The telescopic body helps operators adjust the locator for comfort and storage, while the waterproof search head supports work in shallow water and difficult access points.
RD312 is made for crews who need to locate metal objects quickly and move on. It can be used around common site obstacles, ignores small metal distractions and gives clear audio feedback as the search head passes over the target.
RD312 suits recovery and inspection work where the target is a buried metal cover, valve, tank or surface.
Find buried or hidden valve boxes faster before inspection, repair and reinstatement work.
Reduce time spent searching for covered or overlaid manholes on roads, yards and utility sites.
Locate metal vault covers under shallow surface material without a complex locating setup.
Search for buried metal tanks and large metallic surfaces during investigation work.
Detect reinforced rods in concrete where quick metal confirmation is needed.
Recover metal covers and objects while ignoring small nuisance items like coins and cans.
A low-friction workflow for site teams that need quick confirmation of buried metal objects.
Use the simple ON/RESET and OFF controls to begin searching quickly with minimal setup time.
Adjust the telescopic body and head angle for comfort, storage and access around site obstacles.
Follow the changing audio tone to identify the presence and strongest response from buried metal.
Search near metal fences, under parked cars and in shallow water without losing practical accuracy.
RD312 is built for straightforward work: switch on, scan and listen. It helps teams reduce wasted time looking for buried covers and metal objects.
The locator automatically adjusts its sensitivity to the local environment, so operators can search near common site obstacles while maintaining target response.
RD312 is suited to metallic covers, valves, tanks, rebar and buried surfaces. It is designed to ignore smaller nuisance metal so crews can focus on the target object.
RD312 is best selected when the locating task is metal-object recovery rather than route tracing.
