Eliminate the guesswork with this center detect Stud Finder that has a detection depth of 3/4 in. for wood and metal.

  • Worked for me!
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. ... show more

  • Works as Intended — Simple and Reliable
This works exactly as intended. It’s simple to use and does a good job of locating studs without a lot of guesswork. The LED arrows make it easy to see where you are on the wall, which helps make the process quicker and more accurate. Pros: easy to use, accurate, clear indicators Cons: none for me Would I recommend? Yes—solid, reliable tool ... show more

  • Reliable stud finder with room for sensitivity improvements.
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. ... show more

  • Great price and investment
Super easy to use. Bought it for when I put up insulation panels in my garage but I tested it on the wall inside my house. Detected the electrical areas and gives you the center of the stud for perfect nail or screw placement.

  • Stud? What stud? Maybe stud? Sure why not.
After years of frustration, I finally have the sweet release of being able to throw this POS in the trash! Coming from DeWalt you'd expect nothing but top tier, but with this product you'd have a better chance just knocking on your drywall and guessing. Not only does it not find studs, it finds studs that don't exist! So you get to put oh so many extra holes in your wall that make you have to go back to the patch and paint phase! Oh joy! And the cherry on top, when your going back and forth (again and again and again) trying to locate... really anything... it will chew up your new coat of paint, bringing you back again to the paint phase! Phenomenal performance! Do yourself a favor. Spend an extra $20 bucks and get on that actually works. And above ALL else, it goes without saying, go with Milwaukee. ... show more

  • Great size for older hands; high-quality
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. ... show more

  • Difficult to Understand.
There are no instructions included with this item. There are a few worthless drawings, but they did not help to explain the workings.
