10 Best Stud Finder For Plaster Walls 2025 in the United States

The Franklin Sensors ProSensor M210 is a reliable stud finder designed to work well on plaster and drywall walls. Its standout feature is the use of 13 sensors, which is more than typical models that usually have 1 or 2. This means it can detect studs more accurately and show both the center and edges of studs at once, which is handy if you need precise placement for hanging items. It can detect up to about 1.5 inches deep, enough for most interior walls. The device automatically adjusts for different wall types and textures, so you don’t have to fuss with calibration or multiple detection modes—just press the button and start scanning.

It also has a live wire detection feature, which adds safety by alerting you to electrical wires behind the wall. The display uses LEDs to clearly indicate stud locations, making it simple to understand even if you’re not experienced with such tools. This stud finder is durable and well-built, and it runs on two standard AA batteries (not included). On the downside, while the M210 is great for common walls with drywall or sheetrock, it might not be suited for very thick or unusually textured plaster walls that exceed its 1.5-inch detection depth.

The device doesn’t offer multiple modes since it’s designed to be straightforward, which is great for ease of use but might limit some specialized scanning options. If you want a stud finder that’s easy to use, accurate, and helps avoid electrical hazards during home projects, the ProSensor M210 is a strong choice.

The Walabot DIY 2 is an advanced stud finder and wall scanner compatible with both Android and iOS smartphones. It employs cutting-edge technology to visually identify the center of wood/metal studs, track pipes, and detect wires, providing a more interactive experience compared to traditional stud finders that rely on sound cues.

One of its standout features is the ability to detect up to 4 inches (10 centimeters) deep within drywall, making it highly effective for most home improvement tasks on this type of wall. The connection to your smartphone via Walabot's internal Wi-Fi ensures that you do not need a residential or office Wi-Fi network for it to function. The device includes one Lithium-Ion battery, and its lightweight design (8.47 ounces) makes it easy to handle.

Despite its advanced features, it may not be suitable for those who need a stud finder for multiple wall types, particularly plaster walls. Therefore, it excels in drywall applications with visual feedback and deep detection capabilities, but its limited compatibility could be a drawback for more diverse home improvement needs.

The BOSCH GMS120-27 Wall Scanner and Stud Finder is a versatile tool that effectively meets the needs of detecting studs, wood, metal, and live wires behind plaster walls. One of its strengths is the impressive detection depth and multi-mode detection capabilities, making it suitable for locating various materials inside walls.

The device is designed for ease of use, featuring a smooth gliding action across the wall and a user-friendly color-coded illuminated marking ring that facilitates quick and accurate detection. The audible detection signal, which can be toggled on or off, adds convenience for quick detection tasks when speed is essential. The large, bright LED screen provides clear and easily readable information about the detected objects, including their center, wall depth, and material type, ensuring users can make informed decisions during their projects.

The BOSCH GMS120-27 is also durable, with an IP54 rating and shock-absorbing rubber casing, making it reliable for use on tough job sites. Weighing 10.2 ounces and with dimensions of 7.32 x 3.4 x 1.3 inches, it might feel slightly bulky for some users. Despite this minor issue, the BOSCH GMS120-27 remains a high-quality and accurate professional-grade scanner that is beneficial for both DIY enthusiasts and professionals looking for a reliable stud finder for plaster walls.
