• 【New Upgraded 7-in-1 Wall Detector】 The 2026 upgraded wall detector features optimized signal recognition logic, enhancing its ability to detect wooden studs, metal studs, pipes, rebar, and live wires within plaster walls, helping you make safer and more confident installation decisions before drilling.Results may vary depending on wall structure.
• 【Optimized Sensor Sensitivity】 Improved sensor calibration helps deliver more stable and reliable readings during wall scanning, reducing inconsistent signals and improving overall detection confidence. The device provides clear maximum detection depths for different materials: up to 120mm / 4.72inches for metal objects, up to 50mm / 1.97inches for AC wire detection, and up to 38mm / 1.49inches for wood stud.Performance depends on wall material and density
• 【Enhanced Level Accuracy】 Enhanced accuracy of the crosshair laser level and bubble level eliminates crooked installations. The 3R-rated laser projects clear crosshairs up to 15 feet away, while the 90° and 180° bubble levels ensure perfect horizontal and vertical alignment. Using both together achieves neater and more precise alignment, simplifying your workflow for hanging photos, nailing, and writing on walls. Even DIY enthusiasts can easily use it.
• 【Multiple Auxiliary Functions】Equipped with dual 5-inch (13 cm) side rulers, allowing for quick measurements without a measuring tape. A powerful surface magnet helps you quickly locate rivets, nails, or screws on the wall. The high-definition backlit LCD screen clearly displays the target center and signal strength even in low-light conditions. Furthermore, an audible alarm sounds when a target is detected, helping you quickly and accurately locate the target.
• 【Dual Protection with Automatic and Manual Calibration】The upgraded SUNMAY wall detector automatically calibrates for foreign object and metal mode. During detection, remove the detector from the wall for 2s, and then place it back on the wall for 2s to complete automatic calibration. For AC mode, manual calibration is required. Remove the detector from the wall, ensuring there are no nails, AC power cords, or metal objects nearby, press and hold the MODE button for 2 seconds, and release after hearing an alarm to complete manual calibration.
• 【12-Month Warranty】Comes with a 12-month warranty for reliable product support, helping ensure a worry-free experience and confident long-term use.
