10 Best Franklin Sensors 2025 in the United States

The Franklin Sensors ProSensor M210 is a high-accuracy stud finder designed for home improvement and construction tasks involving drywall and sheetrock. Its standout feature is the use of 13 sensors, which provides more precise stud detection compared to typical models that have only one or two sensors. This allows the device to identify both the center and edges of studs simultaneously, helping users find single or double studs and even irregular stud arrangements. It has a detection depth of about 1.5 inches, which is sufficient for most interior walls. The display uses precision LEDs, giving a clear visual indication of stud location without complicated readings.

One big plus is that the M210 requires no calibration, simplifying its use for beginners—just press and hold the button to scan anywhere on the wall. Additionally, it includes a live wire detection feature to help avoid electrical hazards. The device runs on two AA batteries, which are not included, and is compact and durable, suitable for regular use. Some users may find the price a bit higher than basic stud finders, and while it excels at accuracy, it’s mainly designed for interior walls, so it might not work as well on very thick or unusual surfaces.

The ProSensor M210 is an easy-to-use, reliable stud finder that offers excellent accuracy and helpful extra features, making it ideal for DIYers and professionals who want to avoid guesswork when locating studs.

The Franklin Sensors ProSensor MAX is a highly reliable stud finder that stands out with its 13 sensors, which is much more than typical models that usually have just one or two. This means it can detect studs with great accuracy, even through thick walls up to 2.5 inches deep. It’s especially useful if you have walls made of multiple layers like drywall, plywood, or plaster, or walls with tile, where many other stud finders struggle.

The LED display is wide and intuitive, showing not only the center of the stud but also its edges, helping you avoid mistakes when hanging shelves or pictures. It’s easy to use too—no complicated setup or calibration is needed; just press a button and scan. The device is also built tough and includes handy extras like a built-in bubble level and a pencil holder, which are nice touches for both DIYers and professionals.

One small downside is that it requires two AA batteries, which aren’t included, so you’ll need to purchase those separately. Its larger size (about 9 by 4.5 inches) might be a bit bulky compared to smaller stud finders, but this is a trade-off for its wider scanning area. If you want a stud finder that gives clear, trustworthy results on a variety of wall types without fuss, the ProSensor MAX is a strong choice.

The Franklin Sensors ProSensor M150/X990 Stud Finder stands out for its advanced technology, boasting 9 sensors that enhance its accuracy significantly compared to traditional stud finders that typically have only 1 or 2 sensors. This means you can expect precise readings, including the center and edges of studs, which can be very helpful for various projects around the home. Its maximum detection depth of 1.5 inches allows it to work effectively through drywall and other materials, making it suited for most home improvement tasks.

Ease of use is another highlight. The ProSensor M150 operates with a single mode that adjusts for different depths and materials, requiring no calibration. You can start scanning anywhere, even directly over a stud, minimizing the chances of false readings that are common with other models. The LED display clearly shows the location of studs, which is user-friendly, especially for those who may not be familiar with stud finders.

However, while the features are impressive, there are some downsides to consider. The device operates on AAA batteries, which are not rechargeable, so you'll need to keep a supply on hand for continued use. Additionally, while it does have live wire detection, this feature is not available in all stud finders, so users should ensure they’re utilizing it correctly for safety.
