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

The Franklin Sensors ProSensor M210 stud finder is a solid choice for anyone looking to work with plaster walls, especially DIY enthusiasts and professionals. One of its standout features is its use of 13 sensors, which enhances accuracy in detecting both wood and metal studs. This means users can rely on the M210 to find studs with confidence, reducing the chances of drilling into the wrong spot.

Another useful feature is the live wire detection, which prioritizes safety during projects. The device’s wide LED display shows the center and edges of studs simultaneously, making it easier to pinpoint exactly where to drill. The automatic adjustment for different depths, materials, and textures up to 1.7 inches adds versatility, accommodating various wall types and conditions.

There are a few aspects to consider. While the M210 is designed to be durable, its reliance on batteries (two AAA batteries required) might be seen as a drawback for those who prefer rechargeable options. Additionally, while the display is helpful, some users may find it requires getting used to, especially if they have previously used more traditional stud finders. In terms of portability and ease of use, the device is lightweight and fits comfortably in hand, making it ideal for construction or renovation tasks.

The Franklin Sensors ProSensor M150 stud finder stands out in the category of tools for detecting studs in plaster walls, thanks to its unique features and user-friendly design. With nine sensors, it offers a high level of accuracy, allowing you to detect studs up to 1.5 inches deep. This is notably better than conventional models that typically use one or two sensors. The LED display is an excellent addition, showing both the center and edges of studs, which helps you clearly identify their locations and configurations. It also effectively scans through drywall and other materials, making it versatile for various home improvement tasks.

The M150 is praised for its ease of use; there's no need for calibration, and you can start scanning anywhere, even over existing studs. This can prevent false readings and enhances the user experience. Additionally, the inclusion of live wire detection adds an important safety feature that distinguishes it from many competitors.

However, there are a couple of drawbacks to consider. While its durability is a strong point, the ProSensor M150 requires AAA batteries and does not support rechargeable options, which may be less convenient for some users. The product is also slightly bulkier, weighing around 5.1 ounces and measuring 5.51 inches long, which could make it less comfortable to hold for extended periods.

The ProSensor M150 is an excellent choice for DIY enthusiasts and professionals looking for a reliable and accurate stud finder specifically for plaster walls. Its combination of advanced sensing technology and user-friendly features make it a top contender in its category, although potential users should be aware of its battery requirements and size.
