Stud Finder, 3/4”, Locate Framing Studs Efficiently with LED Arrows, Ideal for Wood and Metal, AAA Batteries Included (DW0100)

The DEWALT Stud Finder (DW0100) is a great example of DEWALT’s reputation for dependable, no-nonsense tools. I’ve used several stud finders over the years, but this one stands out for its accuracy, simplicity, and solid build quality. It’s designed to locate wood and metal studs up to 3/4” deep, and it does so quickly and reliably. The LED arrows are bright and easy to read, guiding you right to the center of the stud with minimal effort. I especially appreciate how intuitive it is — just press it against the wall, slide it slowly, and the LED indicators do the rest. The ergonomic design fits comfortably in your hand, and it feels sturdy without being bulky. It also comes ready to use with AAA batteries included, which is a nice touch. I’ve tested it on drywall, plaster, and even some textured walls, and it consistently gave accurate readings. If you do home projects, hang shelves, or mount TVs, this tool makes the job much easier and helps you avoid those “missed stud” mistakes. Pros: Accurate stud detection for wood and metal Clear LED arrow indicators Easy, one-button operation Includes AAA batteries Compact, comfortable design Cons: Limited to 3/4” depth (not for very thick walls) Verdict: The DEWALT DW0100 is a simple, reliable, and accurate stud finder that gets the job done without any fuss. Perfect for DIYers and professionals alike who want dependable performance at a fair price.

So I was very skeptical to purchase this after seeing the reviews, however it was on sale and I love DeWalt products plus I like to develop opinions based on my own experiences so I bought it to give it a try, at first I when holding it outside the package I thought to myself this is so lightweight and cheap now I see what everyone was talking about. However when I tested it several times over and over it was spot on atleast 90-95% of the time! Both with studs and live wire! Not saying the folks who couldn’t get it to work don’t know what they’re doing but for me it really did work and I was very pleased with it, even tested it against a 3 in 1 more expensive finder I have and this was quicker to detect the objects and from much further away as compared to my “better” one. For the folks who can’t get it to be accurate I would not read the instructions but watch the video so you can see how to really use it, make sure your walls aren’t too thick, make sure they are actually drywall and not plaster or any other material, make sure you lay it flat on the wall and hold the middle button until the lights minus the power light go off, make sure your moving it in one direction on the wall not changing your height or position on the wall it should be slow smooth slides in one direction also not up and down and back and forth on the wall, just one clean slow uni-directional movement. Also you have to keep your hand in the same position once it’s on the wall you can’t be moving your fingers or hands at all, this will throw off the calibration, you also need to make sure your opposite hand and arm are at your side and away from the hand with the finder if you touch the wall with your other hand or even bring it near the hand your using to locate the stud it will throw off the calibration. If you do all of these steps and it’s still not working for you maybe it isn’t the best product and I lucked out. However I must say I am fully impressed by this stud finder.

The DEWALT Stud Finder (DW0100) is a solid tool for locating wood and metal studs with ease. Its LED arrow indicators are clear and helpful for pinpointing the edges of studs, and the compact design makes it convenient to use in tight spaces. Powered by AAA batteries (included), it’s ready to go right out of the box, which is a thoughtful touch. In my experience, the stud finder worked well for most standard drywall applications. It quickly detected framing studs, and the LED arrows provided a clear visual guide for marking. The build quality feels sturdy and reflects the dependable reputation of DEWALT tools. However, the sensitivity of the device could be better explained or refined. There were moments when it gave inconsistent readings, particularly when scanning areas with uneven wall textures or multiple materials. For example, it occasionally detected false positives or struggled to maintain consistency across a single wall. After some trial and error, I found that holding it steady and double-checking the same area improved accuracy, but it would have been helpful if the manual included tips for optimizing use or explained how the sensitivity settings work. Delivery was on time, and the packaging was secure. Despite the learning curve with sensitivity, this is a dependable and efficient tool for home improvement projects. A clearer sensitivity adjustment or enhanced instructions would make it a 5-star product.

Excellent stud finder. My neighbor had been nagging me for years to get one because every time I wanted to do something on my walls or drywall. I had no tool and I was constantly borrowing hers. DeWalt lives up to its usual high-quality item. Very easy to use, big enough if you have arthritic hands to slide all across the wall. I had no trouble locating the studs in order to install a set of shelves in my kitchen. As usual, the yellow color makes it very easy to locate in case you set it down on something it doesn’t easily get buried amongst your work stuff or other clutter. Highly recommended.

Buen producto

It's on point finding electrical wires. I haven't tried wood yet!

I tried two other stud finders on an insulated stud wall and neither worked correctly. This one found the studs easily and accurately.

Absolument pas fiable, trouve tout et son contraire, bien trop peu de senseurs à l'intérieur pour qu'il ai une réelle utilité

Muito bom.Recomendo.
