Magnetic Stud Finder

The oldest type of stud finder is the magnetic type. Just as the name suggests, it uses powerful magnets to pinpoint the locations of metal nails and screws that are in studs walls. Some use one magnet and some use more. They don’t detect the actual stud but they detect the nails or screws that have been used to build the stud. This leaves a little bit of an uncertainty on how wide or long the stud is.

Electronic Stud Finder

The most common type of stud finder is electronic. You get a much more accurate answer, detecting where each stud starts and finishes. The electronic stud finder can detect where each stud starts and finishes giving you a more accurate location of the stud. It senses the different thickness inside the wall to get its data. These stud finders usually have a range of 1 inch before the sensor cannot detect.

Radar Stud Finder

These type of stud finders are ones that use radar technology. They can be more expensive but really accurate in finding studs, pipes and live wires. It uses pulses of radio energy that reflect back when it comes in contact with objects.

The Zircon e50 finder comes with a lot of handy features for the small price tag. It is capable of detecting both wood and metal studs, and can also detect live AC wires. The finder has two scanning modes, 1 is the stud scan mode which can be used for studs up to 3/4″ and the 2nd mode is deep scan for a maximum of 1.5 inch. The finder will flash and beep once it has picked up the edge of a stud. It uses a 9volt battery and has a easy to read LCD screen.

The Zircon e50 scans only one point and finds the stud edges so you will need to mark both sides of the stud. When we tested the wire detection feature we had mixed signals, some times we had a signal by the finder and other times we had nothing even though I know there is a live wire there.
