A stud finder is a must-have tool. It is very easy to use, and it can help you save a lot of money when you want to repair, maintain, or install new wires in the wall. But there are three types of this tool, categorized by the technology they use to see beyond the wall. And each of them has different pros and cons.
Magnetic Detection
The term magnetic will make you think that they are the best. The truth is that in some situations, they can be a joke. This is because they do not sense the stud but instead uses the nails on the wall to detect it. Since the nails are not continuous on the wall, it might take you a lot of time to get as you would have to keep sweeping along the walls for a good period. The good thing with magnetic studs is that they are cheap. So if you know that you are not that stable financially, then they can be of great assistance to you.
Metal Sensor
Their functionality is not far from that of magnetic types. Like the magnetic ones, they too do not sense the stud but the nails and any mental that is along the wall. However, it is good to mention that their effectiveness is far better when compared to magnetic ones. This is because they share their working principles with the treasure hunter metal detector. This, therefore, means that they can detect the resulting magnetic field and therefore becomes more reliable. They are a bit expensive, but the truth is that they are better than the latter and yet still not very reliable.
Ultrasound
These can be said to be the best as far as the world of stud is concerned. They are capable of detecting the stud directly. Here, you only need to know how to make proper use of it, and you will always enjoy using it. With ultrasound, it takes you a few minutes to detect stud. So instead of wasting your money on magnetic types, you know what to do. You, however, need to understand that with ultrasound, you will have to deep into your pocket a bit deeper.
