Minelab X-TERRA 705 Gold Pack

The Gold Pack was the X-TERRA 705 configured for prospecting, shipped with the 18.75 kHz coil that turns the machine into a genuine small gold detector rather than a coin machine that occasionally finds a nugget. The higher frequency plus the 705's ground balance made it usable in mineralized wash, and swapping back to a lower frequency coil gave you your coin machine back. A versatile package, and the reason a lot of prospectors bought a 705 in the first place.
