Metal and Wood Detector Unit UT387E — detection depth: metal up to 100 mm, wood up to 38 mm

The Unit UT387E is a handheld metal and wood detector designed to locate metal and timber behind walls, floors and other building surfaces. It identifies metal objects at depths up to 100 mm and wooden studs up to 38 mm, providing visual and audible signals to indicate the presence and approximate position of the detected material. The compact design and simple controls make the UT387E suitable for pre-drilling checks, renovation work and safe fixture installation where avoiding hidden elements is important.

Advantages

The detector combines dual-mode sensing for metal and wood with clear visual LED indication and an audible alert, allowing quick confirmation of targets without complex setup. Its lightweight, handheld form factor and straightforward user interface enable rapid scanning of walls and surfaces. The depth detection ranges cover typical domestic and light-commercial use cases, helping reduce the risk of drilling into nails, pipes, or studs. The device operates without requiring specialized training and is practical for on-site checks.

Suitable for

• Locating metal objects such as nails, screws, pipes and conduit behind drywall or plaster
• Detecting wooden studs and timber framing before drilling or cutting
• Pre-installation checks for mounting shelves, cabinets, TVs and bathroom fixtures
• Renovation and maintenance tasks where hidden elements must be avoided
• Quick site checks by handymen, electricians, plumbers and installers

Key specifications

• Detection modes: metal detection and wood/stud detection
• Metal detection depth: up to 100 mm (depending on object size and material)
• Wood detection depth: up to 38 mm (depending on wood thickness and density)
• Indication: visual LED and audible signal
• Form factor: handheld, lightweight housing for manual scanning

How to use

Switch the Unit UT387E on and select the appropriate detection mode (metal or wood). Hold the unit flat against the surface and move it slowly across the area to be checked, keeping the sensor parallel to the wall. Observe the visual LEDs and listen for the audible signal to locate the strongest response; pause and sweep the area to confirm the position. Mark detected locations with a pencil before drilling, cutting or fastening. Power the unit and check battery level according to the manufacturer’s instructions.

Recommendations

Scan the surface slowly and in overlapping passes for consistent detection. For more reliable depth indication, perform multiple scans from different angles and avoid scanning over areas with heavy insulation, metal mesh or dense composite materials that may affect readings.
