Description

Eliminate the guesswork with this center detect Stud Finder that has a detection depth of 3/4 in. for wood and metal. While traditional stud finders locate the edge of the stud, this one locates the center for a more efficient read. The finder is constantly calibrating to save time during use. Once the stud is located, an audible alert and directional LED arrows clearly notify the user. You can easily mark the center of the stud with the center marking channel.

    • Always works
I bought this several years ago and it worked wonderfully. And another house I have I decided to buy another stud finder and I bought a cheap one and it did not work. I then bought one of these and it once again it was perfect I highly recommend it.

    • 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

    • 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

    • Garbage dewalt gimmick product
Tried this on my office wall that I had built a few years ago. Apparently, I live wires all through out my wall and only put a stud about every 2 foot. Honestly, Dewalt's quality and innovation has really gone downhill since they moved everything to China and Mexico. This is just a gimmick device that Dewalt came out with in reaction to other tool brands coming out with new stuff. I knew it was going to be bad when I opened the package and found two batteries of the "Daily-Max" brand to which they put a piece of paper over so you couldn't see the brand. Then, when you install them, you see just how much of a piece of garbage this "tool" is. I'm returning this and going to try and find a Milwaukee brand or just go back to zircon. ... show more

    • Decent
This is useful but lacking. I thought with this brand that I would be getting something much better. I get a lot of false readings and it's having a really hard time reading through 1/2 drywall even though it is supposed to work for 3/4 inch. I like the design and the features but it's just lacking for me. ... show more
