Years ago, i saw a t.v. show where some guys, using radar equipement were looking for and finding gold in abandoned mines. ¿Is this really possible and what kind of equipement is necessary?

That one who looks for, find out.
"Borehole radar is based on the same principles as ground penetrating radar systems for surface use, which means that it consists of a radar transmitter and receiver built into separate probes. The probes are connected via a cable (optical or coaxial) to a control unit used for time signal generation and data acquisition. The data storage and display unit is normally a Lap Top computer, which is either an integral component or is built into the circuitry of the control unit. Borehole radar instruments can be used in different modes: reflection, crosshole, surface-to-borehole and directional mode. Today's available systems use centre frequencies from 20 to 250 MHz."
Looks like they are just looking for density differences.

some rocks are more transparent to radar than others. Rocks with water filled pores are the worst for penetration. In general 10-20 feet is all you can get
Metal detectors make an ac field and rely on a piece of metal acting to disturb that field and this changes the current needed to maintain the fieldl.
They suffer from poor performance in wet soil as well. You can get a few feet in dry sand. Larger coils allow deeper operation, but larger coild miss small items. = a tradeoff.
