What is a Stud Sensor?

Stud Sensor1When you’re tackling a home DIY project, the stud finder tool is going to help you to perform a number of tasks, and it’s a great addition to any home tool kit. This tool is not only handy and versatile, it’s also essential when it comes to projects that involve drilling, screwing, or hammering into the walls.

When you’re an experienced carpenter, you know how to use your knuckles to locate a stud, and knocking on the wall will create a different sound when there is a stud present. But some of us aren’t professionals, and we need a tool to help us locate these things. In this guide we’ll talk about the key features of a stud sensor, so that you can make an informed purchase.

Features of Stud Finders

If you’re hanging or securing anything on the wall, you need to keep in mind it’s important to avoid any studs or framing elements that might be beneath. Locating studs is not always an easy task, and that’s why a piece of equipment might be necessary to get the job done. You’ll see that stud sensors come in many different styles and types, and it’s important to know the difference before you make a purchase. You also need to know which kind of finder works best for a given project. Here are the key features that you need to look out for on a stud sensor.

Magnetic or Electronic

There are two types of stud finders, and each has its own benefits and problems. You’re going to need to choose between magnetic models, and those that contain an internal capacitor. The difference is really going to come down to personal preference, but there will be factors at play such as type of wall you’re working with, budget for tools, and ease of access.

  • Stationary Magnetic: There are two types of magnets that you’ll find in magnetic stud sensors, and these are either stationary or moving. With a stationary magnet, you get just what the name suggests. This is a magnet that is not moving, and used to detect the stud under the surface of the wall. When you pass over a stud or screw, you’ll feel a pull or force as the magnet is detecting it. This is very useful when you’re using equipment on drywall, because the screws and studs are going to be quite close to the surface, and this makes them easier to detect. But, on plaster walls the screws are going to be buried much more deeply, almost half an inch, and that means that a stationary magnet isn’t going to be strong enough to find them.
  • Moving Magnet: To get even better range, you’re going to need to get a neodymium magnet which is free to move. This is a rare earth metal that is an extremely strong magnet that has the ability to freely move within the housing of the stud sensor, and this makes it capable of detecting studs through practically any surface. This magnet is going to move at a speed that is relative to the depth of the metal, and that means that with a drywall stud you’re going to get a deep thud, and with a plaster wall you’re going to get a softer sound.
  • Stud Sensor2

  • Internal Capacitor: This second type of stud sensor uses a plate that detects changes in electromagnetic composition of the wall. This change in density will mean the framing stud has been located. This is the most common type of stud finder that you’re going to find, and there are three different sub types.

    1. Edge Finders: The edge finder detects the changes in wall density that is often indicating the edge of a framing stud. This is the most inexpensive model that you can buy.
    2. Center Finders: This device has multiple sensors to detect the various changes in the electromagnetic flux. That allows you to pinpoint the center of a stud in the wall.
    3. Instant Finders: This kind of finder has multiple sensor plates with multiple sensors that can be placed completely across the wall. This is used to not only find the center of the stud, but also the location of various different studs at the same time.

Buying Considerations

When you’re ready to purchase a stud finder, there are certain things that must be considered to make an informed decision. Here are the areas that you need to look at to ask yourself some key questions.

  • Cost: When you’re doing a DIY project, you always need to factor in the cost of your tools. The price for a stud sensor can vary dependent upon the brand, condition, construction, and complexity of the device. You want to have a budget in mind, because this will narrow down your research and give you various options within your price range.
  • Condition: It’s possible to find a stud sensor that is either new or used, and the condition will vary among these. It comes down to the preferences of the individual, but the condition of the product will effect the price.
  • Brand: There are many different manufacturers of stud sensors, and again this will largely come down to personal preference, and it will also affect the cost. Some major brands include Stanley, Zircon, and Bosch.
  • Purpose: You always want to keep in mind how your stud sensor is going to be used. If you’re using this device professionally then you want to definitely invest in something that is going to perform the given task, but if you’re a casual DIY worker, then you may not need to spend so much.
  • Buying a Stud Sensor Online: There are a number of places online where you can purchase a stud sensor, and it really comes down to where you feel most comfortable doing your shopping. It’s possible to get one on eBay, or any online retailer that sells the top brands at discount prices. Amazon is always a great website to make this kind of purchase, and the top rated stud sensors are sold there.
  • New Innovations: Technology is always getting better each and every day, and the same goes for stud sensors. If you want the latest and greatest, then it’s best to look for the most updated device possible. Each year new stud sensors come out on the market, so read reviews for these and see what level of customer satisfaction they have.

Final Thoughts

You can use stud finders in so many different ways, and there are a number of different options that you have when it comes to purchasing one. You always want to make sure that the device that you get works with the requirements of your specific job. This is the most important consideration and something that some workers take for granted. There are numerous different sites online where you can find this tool, but it’s always advised that you go into a retail store as well so that you can work with the tool that you’re considering buying.

Stud Sensor3You want to make sure that it’s lightweight enough to carry on the go and comfortable to hold in your hand. Although most stud finders aren’t too expensive, you’re going to find that the ones that are expensive are intended for professional use and will be made from the highest quality materials. It’s always smart to look for a sensor that is backed by a warranty, as this will ensure that it’s going to stand the test of time.
