Question: What is the difference between a metal detector and a GPR?
A metal detector uses two coils, one sends and the other receives, to pick up on targets in the ground. When a target is found, a current is formed, the receiver coil takes the signal and amplifies it to be heard through a speaker or headphones. No image is given.
A GPR uses radar pulses to send an image back to the software used in the GPR unit.
