Choosing The Best Stud Finder – The Ultimate Buying Guide

Before you actually make the purchase, it is important to know a few basic things about stud finders out there. To help you settle on a model that satisfies your needs, we shall look at some of these, including the different types of finders you will come across.

Types of Stud Finders; Magnetic Or Electronic?

Magnetic Finders

These are the more old school types of stud finders. They work using magnetic energy to discover any screws or mails that are embedded inside the studs. Magnetic finders work well in different kinds of situations. They are, therefore, best used as a kind of supplement for the electronic method.

The major drawback of these models is that they often lack LCD displays, so you won’t really get a detailed estimate of where the stud center is. They also detect other metallic objects like pipes or metal conduits. Therefore, when using metallic finders, you need to be careful about selecting the location of the studs themselves. In most cases, they will be about 16 inches on center.

Electronic Finders

Electronic finders, on the other hand, are the most convenient and easier ways of finding studs inside walls, especially when looking to mount your large 4k TV. They work by measuring the density of a select portion of the wall. After identifying the stud, it will light up (they usually have indicator lights in place). When compared to magnetic finders, electronic finders will come as a little more expensive. They are, however, well worth the extra cost.

Factors to Consider When Buying A Stud Finder

The main fear that arises when purchasing a stud finder is buying one that is inferior and fails to live up to your expectations. Well, you can save yourself the hassle of having to return it by factoring in some of the following points for a smoother purchase experience.

The Price: What Is Your Budget?

Whether magnetic or electronic, most stud finders will be within a reasonable price range. In fact, even the higher-end ones are within most people’s budgets (which is around $20 to $100). However, as a rule of thumb, you stand to get better quality when you sacrifice the extra few bucks for a more expensive model.

In this case, you should consider your particular need with regard to just how frequently you’ll be using it. If you need it for multiple projects, then you’ll be better off getting a pricier higher quality alternative. Magnetic models are cheaper.

The Finder’s Accuracy

Accuracy of stud finders is perhaps the most crucial factor to consider for any stud finder. It mostly relates to how accurately the finder is able to detect the stud without it bringing on a false positive. The accuracy is, in most cases, influenced by the location you are detecting. Be it the wall, floor, or ceiling; you’ll find some stud finders may not have enough power to penetrate through a thicker material like concrete or the floor.

Here, you’ll find electronic type finders to be the most accurate. You can also determine this by looking at the depth stated by the manufacturer or customer reviews about the product. Get to know where the users applied the finders and just how precisely their finders identified studs. The gauge will also give you an idea of how sensitive the finder is.

The Finders Finding Capabilities: What Stud Materials Can It Find?

This refers to the number of different materials your stud finder is able to identify. They’ll mostly include joists, wood, metal, electric cables and AC wires. Some are even able to detect PVC pipes, moisture, and small moving objects inside your wall. For the best results, you should get one with the most versatile capabilities.

Some high-end finders even have additional features that will come in handy in complex projects, like detecting live wires or mapping the wall you are examining. It is important to note that most homes will often have wooden studs, while commercial buildings will have metal studs. Plastic studs are a little bit rarer.

The Sensor Size: Can It House Multiple Sensors?

The sensor size will often determine the amount of time you spend on finding the studs. You see, when the sensor has a wider sensor area, you can cover more space using less time. You will also save yourself from moving around all over the wall to locate the stud. In some models, you’ll find multiple sensors that can be able to detect multiple studs at once. They do this by creating different scanning zones, which are able to function independently of each other.

The wide scanner zones also offer deeper penetration when it comes to scans since they can contain more powerful sensor units.

The Grip And Design: How Comfortable Is The Machine?

Since you’ll probably be holding the device in hand for long periods of time, it is best you find a stud finder that is easy to hold while maintaining a firm grip. You will need to move the tool across the surface in an uninterrupted motion to avoid loss of calibration or false readings.

Therefore, to guarantee the smoothest experience, you should ensure that the stud finder is as light as possible with an ergonomic design, so you don’t have any issues operating it. Most models will have a rubber grip padding on their exterior for easier use and comfort.

Additional Features: Each Stud Finder is Different!

Some stud finders may also come with some features that don’t directly influence the functionality but can make the work significantly smoother. This includes a visual display system which will often indicate the exact location of the stud. It may also have LED lights that blink when you come across the stud. Others will visually approximate how far or close you are from the stud, and icons to tell you your battery level or the mode you are scanning on.

Additionally, you can also get alert systems, which are common to most electric stud finders. This includes any visual cues, or beeping noises the device gives you on locating a stud. Alert systems are, however, not as common in magnetic stud finders.

Additional features may also include extra modes, which will allow you to scan through solid surfaces of metal and pipe objects as well as inside concrete blocks or gas lines. Another mode is detecting the live wiring inside the wall so you can steer clear. These extra modes will often be in the pricier models.

Tips When Using a Stud Finder

  • Avoid touching the wall using your other hand while using the stud finder- this may alter the readings
  • Some stud finders need to calibrate before they begin scanning. In this case, you are advised to start away from light fixtures, switches or outlets
  • Mark the studs, live wires or objects you detect with different colors if possible so you can differentiate them
  • Put on some painter’s tape over the region you are scanning so you can mark it without writing your wall
  • Scan above or below the stud you detect to ensure that it continues to the ceiling or floor.
  • Avoid scanning freshly painted walls. The moisture in the paint can affect the results.


Stud finders pretty much have their jobs cut out for them. They find studs. However, they come in different variations whose suitability will depend on the wall materials you are scanning for and the construction.

That said, you should consider all these factors to get a stud finder that is most suitable for your needs. Also, you are advised to use the stud finder while observing where other plumbing or electrical fixtures are placed to help figure things out.
