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 DEWALT Stud Finder (DW0100) is designed for locating framing studs in plaster walls efficiently. It boasts a detection depth of 3/4 inches for both wood and metal, making it versatile for various tasks. The center-find technology, combined with directional LED arrows, helps you locate the center of the stud accurately, which is very useful when you need precision.

The added safety feature of AC and live wire detection is a significant benefit, as it helps prevent accidental drilling into electrical wires, ensuring a safer operation. Users will appreciate the constant auto-calibration feature that saves time and effort during use, while the audible alert provides a clear notification of stud location, adding to its user-friendly design. Additionally, the slim profile makes it easy to handle and store, and the included AAA batteries mean it’s ready to use out of the box.

However, it might have limitations due to its detection depth of only 3/4 inches, which may not be sufficient for thicker plaster walls. The DEWALT Stud Finder is a solid choice for DIY enthusiasts and professionals who need a dependable tool for wood and metal detection in standard plaster walls but might fall short for those needing deeper detection capabilities.

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.
