..of finding gold in noisy ground conditions. Noisy, that is, with other detectors. A recent report is of a thin 0.5gm nugget being detected at an estimated 6in depth in bad Australian ground. The ground was on a slope, just below an old claim, that had been well detected for the past 20years or so. In the same area, a person new to detecting recently found a 20oz nugget that was only about a foot down, so big gold is still there to be had, as well as smaller bits. Now 0.5gm is 1200 times less than 20oz, but it shows that small gold is detectable by the GS5 in adverse ground conditions. The small nugget was first detected with a GP3500 and before being dug, the GS5 user was invited to check the signal. The signal was clear on the GS5 with the coil scanned 1in above the ground surface. The coils used were a Coiltek 14in mono on the GS5, and an 18in DD Coiltek Pro on the GP. It is reported that the GS5 threshold was extremely smooth, while the GP suffered ground noise that made the nugget signal hard to distinguish. Other similar GP signals were checked and gave no response on the GS5. On digging, the signals gradually faded out, confirming that they were ground anomalies.
Another GS5 user, the one whose nugget pictures I posted under POWERLINE GOLD, has found many nuggets in areas that are not only strongly mineralised, but have severe em interference as well. He has reported an interesting observation, that he is finding a greater percentage of spongey and porous gold, than he was getting with the GP. Again this indicates the the GS5 is indeed responsive to poorer, or fragmented conductors, and can hear them through the ambient noise.
Posting of these findings is not intended as a head to head with Minelab, or other, detectors, but it does illustrate that as a prospecting tool, no one detector can be the ideal in every situation. Rather, units with different characteristics can be complementary to each other.
