Australian Students Use Examiner
We picked up a number of targets in the same location and a couple of targets outside that area. Most targets outside Examiner’s search area turned out to be ferrous materials. All the targets (at least all the targets we dug out by now) at that location proved to be non-ferrous materials but none of them gold. We could not tell for sure what kind of metals two targets are made of or their purpose. At our best guess one target looks like a part of silver jewellery, another the deepest one found at 8″ reminds one of a piece of solder cutlery. Two targets close to the surface were clip-buttons. We have not finished exploring the place.

Today we proceeded with our tests. We thought of decreasing “Her Majesty Chance” in getting the right target. Therefore, we used three empty containers and one with gold. Out of 10 tests 8 were successful (Stan scored 100%). We calculated probability of these results being achieved by chance. Well, it is pretty low – around 0.04% by binomial distribution method: n = 10, p of success = 0.25. Then we applied the method you suggested to rule out the unwanted weights. The result is very encouraging: five tries and 100% of accuracy (chance factor is 0.09%). These were all surface targets.
Good Day Rangertell,
Yes, we located those with the help of the Examiner. I took the bronze coin to the dealer to identify -he told me it is of series 1880 but he could not tell the exact date. The silver locket is a bit damaged at one corner and water washed out the picture that was painted on its glass. But we are determined to restore it to its full glory and replace the picture with the opal.
The gold and silver are peeling off the buttons we detected on the same spot, however, it makes them look more authentic. This Sunday we headed to Central goldfields for a short while just to see if a particular place was worth detecting. The place was completely untouched by detectorists. As you know it is both good and bad news because of plentiful bullets, bullet cases and rusties.
But my first find looked promising – a waterworn 4 gram’mer but not of gold but of bright grey substance. Seems I found platinum among round quartz pebbles at a considerable depth. Next to it rested almost on the surface a beautiful silver 6 pence coin of 1941 and a bit aside a copper half penny of 1866, greenish but all the images and inscriptions are intact. Up the slope we dug out a bright white flat nuggetty metal that we cannot bend. What could it be?
We took Examiner with us, and it pointed to an abandoned mine. Very logical but as an area is highly rubbished, and we were short of time, we put off an exploration till the next time. Though in the process we found a half penny coin c.1950. Then he dug out an old Queen Victoria Crown badge from a military cap and Victorian 3 pence coin c. 1900. By the way a cross that I found with a help of Examiner is likely to be a Victoria Cross belt buckle or shoulder buckle.
