[Stud Detection + Laser Distance Measurement] Our multifunctional stud detector not only detects metals (rebar, copper pipes, etc.), cables, and wooden beams hidden behind walls, ceilings, and floors, but also functions as a laser distance meter. It can measure the length, area, and volume of a room, as well as perform addition, subtraction, and volume measurements, eliminating the need for a separate stud detector or laser distance meter. [Multiple Scanning Modes] The multifunctional stud detector offers various scanning modes, with a detection depth of up to: Magnetic metals 3.15in (80mm), non-magnetic metals 3.15in (80mm), AC power cables 1.97in (50mm), and wood 1.5in (38mm). [Voice Function] When the detector locates a target object, the LCD screen displays the distance and signal strength-closer objects result in stronger signals. If the sound is enabled, it will emit a "beep" (which can be turned off). When the device reaches directly above the target object, the LCD screen will show a center marker, indicating the precise location of the target. [Practical Multiple Measurement Modes] In addition, this laser distance meter can measure distances up to 130FT (40m) and offers up to 12 measurement modes, such as single measurement, continuous measurement, area measurement, volume measurement, Pythagorean measurement, addition and subtraction measurements, and more. [Unit Switching and 50 Data Records] You can freely switch between measurement units in the settings: M/FT/IN/ft+in. Additionally, this distance meter can store up to 50 sets of measurement results, allowing you to record, compare, and calculate your measurements more efficiently as you work.
