Minelab X-TERRA 705 Dual Pack

The Dual Pack was the X-TERRA 705 sold with two coils so you could switch operating frequency by switching coils, which is the trick that made the VFLEX platform interesting. One coil for general coin and relic hunting, a second for deeper or trashier ground, and a single machine that behaved like two. It is still a sensible way to buy a detector, and it is why the Dual Pack held its value better than the standard package.
