Factors to be considered while buying a Wall Scanner

Material

There are different kinds of studs used in different types of buildings. Normally the official building utilizes metal studs while the construction of a house may utilize wooden ones or the plastic studs. Some devices are designed to detect only certain types of studs so it is better to shop according to the sort of studs you are going to work over.

Stud Location

The detector should be chosen according to the wall or the place you are going to operate the scanner upon. Some scanners are not suitable for all types of surfaces. So, better to decide the one that is the best fit for your place.

Are you a Professional user or just want to mount the television?

Before buying the best device for yourself, it is important to decide the purpose you are going to use it for. The type and quality will vary according to your needs as the market is flooded with too many options according to different special circumstances. If you are a professional user, i.e. a builder, a carpenter or a plumber then you need a more advanced and accurate device that may not lack accuracy and consistency or a versatile device that is able to perform other kinds of detections as well like tracing the humidity, density or temperature, etc. However, if you are buying it for your home then buying an expensive and top-notch device with all the value-added features is not necessary. You may simply need to mount your television or a wall clock on the wall that can be done with the help of a cheap magnetic wall scanner.

How much does a wall scanner cost?

The price of the wall scanner ranges from 10$ to 200$ depending upon the features it carries. If you want to buy the premium quality with the brand name along with all the modern features like various detection modes, audible detection, self-calibration function, ease-of-use, and other value-added functions then you should have a good budget.

Electronic devices are pricier than the basic models but carry a lot of useful features. However, if you have a tight budget and want to buy something that provides you full functionality at an affordable price then magnetic wall scanners are easily available at a pocket-friendly price.

We will recommend you to buy a device that is not only relatively economical but also features all the advanced options and such a device may cost you in between 30$ to 80$.

What benefits can you expect from a wall scanner

The wall scanner allows you to trace any live AC wires, studs, joists, beams or any support inside the wall to help you decide where to hang the desired item or whether it is safe or not. It can prevent you from any potential hazards. These stud finders can also detect the center of the studs and their edges. They can also detect plastic and metallic material inside the wall. Electronic types are more useful than the magnetic ones because they can detect live AC wires, Stee and copper pipes, PVC pipes, and other items. Some detectors are equipped with the features to detect humidity or moisture content in your wooden walls, ceilings or floors.

Types of Wall scanners/ Stud finders

These devices are found in two types i.e. Magnetic and electronic. However, here we have reviewed all the electronic devices because they have better functionality than the magnetic ones.

Magnetic Wall Scanners

These scanners contain magnets that bang or make a loud sound when it detects ay metal. These kinds of detectors are suitable for thin drywall. However, in the old houses, the screws are placed under the thick or multi-layered wall, therefore, the studs cannot be detected just through a simple magnet and this is the reason we preferred electronic stud finder over the magnetic ones. You should better choose the wall scanner according to the place you are going to use it upon.

Electronic Wall Scanners

Electronic wall scanners are the modern devices to find the studs under the wall. They utilize upgraded electronic sensors that can detect a variety of material under the wall, ceiling or floor. You can even find live AC wires and plastic pipes through these devices and that is why they are expensive than the magnetic ones. They are equipped with other detectors as well that can also detect moisture content or air temperature etc.

Summing Up

Wall scanners are important when it comes to mounting something on the wall and especially for those people who use it professionally. So it is important to buy them considerately keeping all the important factors in mind, whether you are buying it for your personal use or for the professional purpose.

Nowadays, wall scanners are equipped with various modern features that make your life easier than ever. So, that is the reason we reviewed a lot of useful devices followed by a very helpful and comprehensive buying guide that will help you out through the journey of buying one best fit for your needs.
