  • Simple and effective. Replaced electric stud finder
Size: Single
I switched over to this old school magnetic stud finder. I'll never go back to the electric wall scan styles. This is quick and accurate. I love that I can leave it up on the screw it found and mark what I need to. So much easier.

  • Very strong magnets and am fond of the built in level
Size: Pack of Two
The media could not be loaded. I have a reliable battery operated stud finder but also wanted a more compact and battery-less one to use on thick walls or to double check walls with inconsistent framing. My father had one from the early 80s that used to pivot and had notches for marking off the where a screw was found, but I couldn't remember the brand and haven't found the identical model. I'm building out a closet from a closet kit where the closet wall is shared with the laundry machine, dryer, electrical and plumbing and wanted to be sure that what was detected as a stud was in fact a singular object such as a screw head and not something else like a copper or ABS drain pipe. Having two stud finders helped me to easily determine the distance between studs without making any marks on the wall (I usually use painters tape and mark on the tape). I found the magnet to be very strong but have not tried it on plaster or other non-drywall surface. I also found the level to be useful to vertically line up the framing. I looked at a few other magnetic stud finders and even possibly 3D printing my own, but ultimately chose this 2-pack for the built-in bubble level and notches for accurately marking the detected screw/nail head. I also have a few other Klein tools (e.g. Scout Pro for ethernet/coax cable testing, non-contact voltage tester, tone generator and tracer) that have worked well for me so this seemed like a safe bet. For me, this stud finder is the best and most compact solution. ... show more

  • Works! Very tiny.
Size: Single
Well, I have seen some people reduce stars for similar products because they were very tiny. This one is very small as well. Consider that in mind. As for me, it's a perfect size. We have small hands, and it's nice when it takes up less space in my toolbox. Originally, I wanted to support a local small business and order The StudBuddy, but they deliver it in 2 weeks to my city. And I liked their design more. Maybe next time.

  • Wow
Size: Single
The media could not be loaded. Saw these kind of tools in a video and I am very happy to of purchased one. My older tools use the void/non-void detection method and are okay but with the batteries you never can be absolutely certain that they are functioning to their newer condition. This tool works extremely well and with no batteries needed it makes jobs easier. The rare earth magnet is surprisingly strong and really grabs tight. I trust this brand for long years of service and thats important. Color is bright orange with black so you can spot it fairly easily in your toolbox. Locating method is simple and fast and easy to understand. ... show more

  • Solid, simple, and does the job — with a couple small quirks
Size: Single
I picked up the Klein magnetic stud finder for some wall-mounting projects and overall, it’s been a dependable little tool. It’s simple — no batteries, no beeping — just strong magnets that latch onto screws or nails in the studs behind drywall. What I like: The magnets are strong — once it catches a screw head, you know you’ve found your stud. Lightweight and pocket-sized, so it’s easy to keep on you while working. No calibration or fuss — works right out of the box. What could be better: Because it relies on finding metal fasteners, it can be less helpful if your studs don’t have screws/nails where you’re searching. Not as precise as an electronic stud finder for centering studs — you still have to guess a bit. I gave it 4 stars because while it’s reliable and well-built, it’s not foolproof in every wall type. For quick jobs and basic drywall, it’s a great choice — just know its limits. ... show more

  • Clever tool
Size: Single
I was skeptical, but this little sucker really works! Move it across the sheetrock, and when it comes to a stud, it grips the wall tightly.
