I had a brief chance to try the small coil out for the Vista Gold. I hit this area previous and it is littered with nails and can slaw. Was looking for musket balls and maybe some Indian brass points. The coil did locate a bunch of non ferrous targets (mostly can slaw) but also hit on a deep broken spoon at about 8" The coil ran quiet at max sensitivity, with only a hint of high pitch chatter . Overall a great little coil. I think the Vista Gold is a good relic machine for my needs.
