Is the Explorer a fixed ground balanced machine?

There is nothing in the instruction manual about it and assume that it must compensate by using different frequencies. I presume that this is why it is no good on the gold fields.

Mick,

The Explorer is a time domain machine using a rectangular excitation voltage. The detector examines the receiver coil wave shape to qualify a target.

It is my understanding that the detector looks for changes in the signal shape as the coil is swept. If the ground is homogeneous (regardless of its mineralization), then no target identification is given. Only when a change is detected is a target indicated. This is just my opinion which may not be worth much.

HH,

Thanks for having a crack at the question Glen. Not sure if it helped, but thanks for trying.
My best guess of what you are saying, is that the Explorer was designed from a completely different approach to how we think about detectors. To continue my guess, the Sovereigns have a similar technology in them, but also include ground balance and ground tracking, neither of which exist in the Explorer's. From this, I can only assume that the Explorers are a fixed ground balanced machine as they don't work in gold fields very well.
If anybody wants to have a go at this, they would be most welcome. It's not a critical question. I'm just interested in understanding the machine a bit more.
