It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

And I was just kidding. If you don't know the answer to that question you asked, you don't know what a GPR is.

GPR has many applications in a number of fields. In the Earth sciences it is used to study bedrock, soils, groundwater, and ice. Engineering applications include nondestructive testing (NDT) of structures and pavements, locating buried structures and utility lines, and studying soils and bedrock. In environmental remediation, GPR is used to define landfills, contaminant plumes, and other remediation sites, while in archaeology it is used for mapping archaeological features and cemeteries. GPR is used in law enforcement for locating clandestine graves and buried evidence. Military uses include detection of mines, unexploded ordnance, and tunnels.

Before 1987 the Frankley Reservoir in Birmingham, England UK was leaking 540 litres of drinking water per second. In that year GPR was used successfully to isolate the leaks.[2]

Borehole radars utilizing GPR are used to map the structures from a borehole in underground mining applications. Modern directional borehole radar systems are able to produce three-dimensional images from measurements in a single borehole.

One of the other main applications for ground penetration radars to locate underground utilities, since GPR is able to generate 3D underground images of pipes, power, sewage and water mains.

GPR is not GPR. There are so much different version on diff. frequencies and antenna arrangments, that there is no proper Yes or No answer. Larger iron object can be detected, smaller ones can not always be detected or the measured values can not correctly be interpreted.
If you prefer to find metals, than you'd better choose some other sort of detector. Gradiometer/Magnetometer are the right tools for metals.
