Best Stud Finder Buying Guide & FAQ

What to Look For in a Stud Finder

  • Method

The first thing you’ll want to check when buying a beam finder is the method of which that stud finder works upon. You may notice that we’ve included a vast array of different types in our Top Picks, all of which are the best stud finders on the market- but your choice should depend entirely on what you feel comfortable using. The main differences between these stud sensors are written below, when discussing different methods, to help you navigate the choices and decide on the best method for your needs.

  • Features

Features aren’t always necessary, but they can help make a tedious task much simpler, quicker and a little more fun if you’re a geek like us. While the options below aren’t necessary when it comes to finding your wall studs, they’re always handy to have.

  • Auto shut off- shuts down after a set period of time in which it has not been in use, saving energy.
  • Depth detection- Indicates the depth of the stud or beam, as well as the depth of the drywall itself, making it safer and easier to continue working.
  • Display- an LED display can make it much easier to understand where exactly the stud finder is indicating a beam, as well as giving information to the user in a clear manner.
  • Multi-mode- These handy little doo-dads will help you find both metal and wall studs, ensuring you stay clear of the right areas while working around the safest parts of the house.
  • Two-way Level- A simple feature that is usually found in even the most basic stud detector. It’s simple but easy to use and allows you to remain perfectly in line, every time.
  • Hands-free- Somewhat self-explanatory but essentially allows you to continue working without the need to switch hands, constantly.

Different Methods of Detection

Electronic

The majority of electronic stud finders are much easier to use than their magnetic counterparts, due to the screen which gives way most of the essential information. As such, the electronic versions of stud finders tend to be much more popular, and often come doubled-up with a range of handy features. There are three main types of electronic stud sensors:

  • Edge finder

 These are the most common sensors you’ll find. They are easy to use and tend not to be over-complicated. Simply switch on and move the stud finder over the area you are looking to work around, and the screen will indicate the edges of each side of the stud.

  • Center finder

Another popular sensor, as it allows you discover the center of the stud you’re searching for. The on-screen display should simply show you the length between each edge of the stud and you should place the sensor between these areas until they are of equal value.

  • Instant

The most recent stud finder and one that uses multiple different sensors and indicators- making this the more expensive of our options, as you can imagine. The good news, however is that you won’t need to move the tool around too much, to discover your wall beams. Just place the instant stud finder against the wall and the machine will use complex algorithms to accurately locate the stud.

Magnetic

A magnetic stud finder uses a remarkably simple method that should help you feel comfortable finding wall beams, easily. All you need to do is place the beam finder against the surface and move it along, or around, the area you wish to work with.

  • Stationary

When your stud sensor is near a wall stud, you’ll feel a gentle pull from the magnet based inside the tool. These are the cheapest wall stud finders available on the market, as well as the simplest. The issue here, of course, is that a deep wall stud may only have a very gentle pull and might therefore be difficult to detect.

  • Moving

Moving magnetic sensors make an audible sound and have a loose magnet within the tool itself, so you can get a better sense of when a wall beam is below the surface. These are usually a little easier to use, since they tend to contain a stronger magnet, and the audible aspect of their detection makes discovering wall studs much easier.

How To Use a Stud Finder

While each item will have slight variations, the general gist is the same for each type. For magnetic stud sensors, you’ll notice a pull from the tool toward the stud, as you move the sensor around the area. The stronger the pull, the closer you are.

With electronic stud finders, you’ll need to begin by calibrating your chosen stud finders for walls, depending on whether you need a wood stud finder or metal beam sensor. Then slide it along the wall, in the same way as the magnetic sensor. The on-screen display or light indicators will then let you know how close or far away you are.

Finally, instant electronic stud finders will usually use lights or sounds to indicate studs as you move across the wall. These will vary depending on the make and model but are usually pretty straightforward to understand.

Best Stud Finder FAQ:

Q: What is a stud finder and how does it work?

A stud finder is a piece of equipment which allows users to discover studs and beams beneath the surface of the average house, without the need to do extensive research or take apart any sections of said house. These stud finders use a variety of different methods, depending on the type that is being used, to let you know exactly where these beams are based, so that owners can either work alongside or avoid these areas, in order to maintain the integrity of the home. The two main methods used with stud finders are magnetic and electronic. The magnetic stud finder works with magnets inside a small, handheld tool which are attracted to the metals used in studs and beams when the house was built. The slight pull felt by this attraction allows the user to “feel” where the studs are based. Meanwhile, electronic stud finders use a vast array of different sensors and abilities to help indicate the exact whereabouts of these essential aspects of the house. The most common format is one which allows users to discover just the edges of the beams, therefore giving the operator a general idea of where the stud is housed. The most expensive and all-encompassing stud finders, however, will use plethora of algorithms to clearly indicate where walls studs are based, allowing the workmen or homeowner to clearly mark the presence of beams, studs and joists.

Q: What are common false positives when using a stud finder?

Like all things, it is unlikely to create an exact science when it comes to finding studs and beams, without stripping the wall down. However, the more adept you are at using a stud finder, and the higher the quality of the sensor you decide on, will greatly affect the accuracy of your stud finding capabilities. Common false positives depend on the type of wall sensor you are using. For example, magnetic stud finders can easily be misread, especially when the item being used is cheaper or has a weak magnet within the tool. They can also be pulled elsewhere, if there are any other magnetic materials within the walls themselves. This is becoming more common as the materials used in construction have changed greatly from when magnetic stud finders were first invented, and our reliance on metal-based products increases. In electronic stud finders, common false positives come from inexperienced users, who mis-read the display. However, the most likely cause for these false positives come from an incorrect calibration before beginning. Without the correct calibration, the electronic stud finder can easily incorrectly identify the space and distance of the wall, joist, beam or stud. This can therefore mean that the size of the stud has been miscalculated and the project could be placed in peril. Therefore, it’s very important before beginning your project and using your stud finder, that you locate and follow the instructions very closely. It might be a little boring at the time but it can save you heaps of work and a big headache, later down the line.

Q: Can I use a stud finder to find floor joists?

Absolutely. Just be sure to calibrate your electronic sensors to match the required depth, in order to locate your joists accurately. If you’re looking to use a magnetic sensor, be sure to grab a high-quality stud finder that has a strong magnetic pull- we would recommend a moving magnetic stud finder in these cases as this will allow you to hear the differences as the sensor moves over the area, as well as being able to feel the pull of the magnets.

Our Top Pick

The ProSensor 710 from Franklin Sensors easily comes at the top of our list, thanks to its ability to eliminate the awkward calibration process and lack of false positives. This small but mighty sensor uses an incredible 13 sensors to locate multiple studs at any one time and the use of the lighting allows for even the most novice operator to accurately mark studs around the home.

Simply place on the floor and allow your room to light up with accurate readings, perfect for those who just want to mark out their studs, ready for work to be completed. The patented technology can indicate both wood and metal studs, and deep detection allows it to penetrate even the thickest walls, ceilings and floors.
