Basic detector for finding

Mar 24, 2016FYI -- the rental place had both metal detectors and pipe detectors. They recommended the pipe detector because it will go deeper. Are these just super duty metal detectors? Thanks again, John Actually, you're not after depth at all. The markers should be just above the ground, or at the very worst, just an inch or two below the ground. Get price

3 Ways to Build a Metal Detector

Jul 31, 2019The metal detector apps work by measuring changes in the magnetic field of your phone. As you pass over metal, it interacts with this field and the app detects that interaction. These interactions show as fluctuations in the magnetic field as you move from object to object. [7] Get price

How Does Metal Detector Work?

Jun 30, 2020How Does Metal Detector Work? A metal detector usually works by the transmission of an electromagnetic field that generates from the search coil. If any metal objects come within this field range, it becomes strengthened and retransmits their own magnetic field inside the ground. Get price
