Whether you’re looking to install a cabinet or hang up your new TV, stud finders can be valuable tools in many DIY home projects. While you can always fall back on the reliable knock and guess, sometimes you’re unwilling to risk your wall or your appliance and that’s when this tool comes in handy. From the simple magnetic variety to high tech wall scanners, these tools can make simple setup projects a hassle free experience. So today we’re taking a look at the best stud finders in 2021, where to find them, how to use them and how to pick the best one for you. Let’s dive in!
Before diving into features and function, you should determine what kind of stud finder you would need. In order to figure that out, you’ll need to assess your own needs. How often will you be using it and how important is accuracy for you? Are you an experienced DIY-er or just a beginner with an appliance to mount? Once you have your own prerequisites, navigating features, functions and types becomes a breeze.
What Types Of Stud Finders Are There?
There are three main types of stud finders ranging from the low tech to the high tech and high price.
Magnetic Stud Finders
Magnetic stud finders work through a powerful neodymium magnet that is able to detect nails or screws in the stud. More powerful magnets have made this option more and more accurate while the price remains in the low tier.
It’s an excellent choice if you’re just looking to use your stud finder once in a blue moon and don’t want to invest in an electronic one. If you have the patience, it might even be a good long term solution. However, keep in mind that if you’re a complete beginner, a Youtube tutorial will go a long way when it comes to getting the most out of this tool.
Electronic Stud Finders
Electronic Stud finders are currently the most popular option as they’re very beginner friendly and quite accurate. Powered by batteries, these stud finders usually do more than just find the stud and locate its center. Most have additional detection for AC wiring and piping as well as wood and metal detection.
These work through detecting density changes in the wall and they run a bit pricier than their magnetic counterparts. However, you’ll definitely be able to find something in the $20 to $30 range that will serve you for years to come. If you find that ease of use and additional detection are good selling points, this is the stud finder for you.
Ultrasonic Stud Finders
This is the priciest option of the bunch and for good reason. They use sound waves to determine what’s in the wall and they’re usually used in a construction environment rather than for home projects. If you’re serious about your DIY projects or you work in the business - this might be the ideal gadget for you.
Other Features and Considerations
Most stud finders (electronic ones included) will need to be calibrated before use. In fact, this is one of the reasons why so many people end up returning their stud finders, throwing their arms in the air and declaring that the gadget was inaccurate.
Reading the instructions on how to properly calibrate your stud finder will make a huge difference. Also, it will likely be the determining factor in whether your experience is successful or not. Of course, there are many such tools that simply lack the accuracy needed even for home projects. But most of the time, reading the manual and the troubleshooting instructions will take little time but make a huge difference.
AC Wires Detection
This is one of those features that you don’t care about until you do. Most electronic models will have this feature and it’s something to consider if you think that there are any home improvement projects in your future where drilling or mounting appliances or cabinets risks hitting a live wire.
Another common feature for electrical stud finders is one that you’ll want to take into account the more projects you do. The device will usually have a different function or LED color to let you know if you’re in a pipe area.
Sensor Depth Capacity
The depth at which your finder is used to detect is important. A good one should be able to detect at least 1.5 inches into your drywall and probably a bit deeper if it can also spot copper wiring or pipes.
Another great feature to watch out for is center targeting. While finding a stud can be enough, the best finders will also let you know when you’ve identified the center of a stud which can save you a lot of time and calculations. Make sure to recalibrate and follow the manufacturer’s instructions if you plan on using this feature.

A: The best way to identify whether you’ve hit a stud is the old fashioned way - by knocking. A solid sound will mean that there is a stud behind the drywall while a more hollow one means no stud.
Q: Can my phone find studs?
A: There are some apps that use the phone's built-in magnetometer to locate metals in the wall however these won’t be as strong and won’t be able to read as deep as a dedicated tool like a stud finder.
Q: Do stud finders really work?
A: Yes, stud finders work. However, in order to ensure precision you will need a good stud finder and a bit of knowledge on how to operate it.
