How it works. Detector that can find any object inside wall
Fascinating story. Every day we are surrounded by many tools, but we do not even know how they work. Today I want to tell you a tool like a stud finder. These tools are not very often found at home, but sometimes it is very useful. For example, if you want to hang a new TV or shelf on the wall, the stud sensor will help you.

The simplest wall stud detector models use a neodymium magnet, which can only detect metal studs. More advanced models have an ultrasonic sensor, which allows you to detect the stud in the wall, regardless of what material it is made of.

- Edge finders — easily find an edge of the beam.
- Center finders — as you could already guess the model of this category will let you know where the center of the beam is.
- Instant stud finders — this is a more modern development, which has a number of sensors, which will allow you to instantly determine the location of the beam in the wall. How it looks you can see in the photo.
