There are some basic rules that should be at the forefront of your mind when detecting for gold, probably the most important one being to dig everything. No one can accurately determine if a signal is gold just by listening to the signal response, especially if the target is large or close to the surface of the ground. There is another side to gold prospecting with a metal detector that requires a different approach, this is often dictated by expediency due to time restraints and in a lot of cases an attempt to maintain some sanity, these areas are often in and around old diggings where there is a lot of trash from both modern and Old Timers.
As most of you know when the detector heralds a target there are a number of factors indicated by the audio that will allow you to make an informed decision on the likelihood of the depth and size of the target. In this discussion let's assume I’m talking about Monoloop coils in combination with the
GPX 5000, however most of what I’m about to say can correlate to Double-D coils as well.
The size and depth of a target determines the way it behaves when it’s exposed to the transmit field of the detector. It is the eddy currents excited in the target by the transmit field that we are listening carefully for during the GPX 5000’s receive on-time, the deeper the target, the fainter the target audio will be due to the weaker field coming back off the target.
