10 Best Stud Finder For Plaster Walls 2026 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 Stud Finder Wall Scanner by JAXWQ is a strong choice for anyone needing to locate studs, metal pipes, or live wires behind plaster walls. Its intelligent micro-sensor chip allows it to detect the edges and centers of wood studs, metal pipes, and even AC wires quickly and accurately. This makes it practical for home improvement projects like hanging shelves or TV mounts, where avoiding wall damage is crucial.

The device offers multiple scan modes—stud scan for wood, deep scan for larger objects, and metal scan for plumbing—giving it good versatility for different detection needs. It features a bright, backlit LCD that clearly shows stud positions and battery status, complemented by audible beeps to guide users, which is helpful especially in dim settings. The stud finder runs on included alkaline batteries and is lightweight, making it easy to handle.

This tool is well suited for homeowners and DIY enthusiasts who want a reliable, multi-mode stud finder with clear visual and audio feedback, helping to boost confidence and safety when working on plaster walls.

The Franklin Sensors ProSensor MAX Stud Finder stands out for its impressive accuracy, boasting 13 sensors compared to the usual 1 or 2 in traditional stud finders. This results in more precise detection, with a maximum depth of 2 1/2 inches, making it suitable for thick plaster walls. The device is user-friendly, requiring no calibration – simply place it on the wall and press a button to start scanning, reducing the chances of false readings.

It features two detection modes, allowing it to work on various wall types, including multi-layer drywall, lath, plaster, and large tile, making it versatile for different home setups. The wide LED display is another plus, showing both the center and edges of studs, which can be especially helpful for finding irregular configurations that other stud finders might miss. Additional conveniences include a built-in bubble level, a low battery indicator, and a pencil caddy.

However, it requires two AA batteries, which are not included, and its relatively heavier weight of 1.46 pounds might be a slight drawback for some users. This stud finder is well-suited for both professional use and DIY projects around the house.
