Ground Balancing for Hot Rocks

If a prospector ground balances his detector the accurate way in order to compensate for high mineral background it will cause it to give a metal response to hot rocks. This takes place for the reason that hot rocks are fundamentally isolated minerals for which the detector will not be ground balanced for. Fortunately the modern metal detectors are very efficient at identifying them now as long as they are accurately adjusted. Bear in mind how important it is to have the correct design and accurate calibration by its manufacturer for universal use, as well as prospecting. Not all metal detectors are suitable for prospecting. The method for identifying mineral hot rocks is not as complicated as it was in the past, but it does entail practice. In order to check to see if the response is a metal or mineral one, it will be necessary to spot the target with the detector in the all metal mode. Then move the search coil to one side, then lower it a little bit and switch it over to the discriminate mode. The discrimination controls should be set to the level that the manufacturer specifies as the calibrated level for sampling ore. Audio retune the detector if you need to, according to the instructions of the manufacturer. Now that you have a consistent sound coming from the detector, pass the search coil over the target. Make sure the search coil is at the same distance from the ground as was formerly pointed out. Keeping the search coil at a same height might require a little bit of practice at first however it can be done. If the level of the sound goes down or silent, it means the target is oxide or magnetic iron ore. Keep in mind that these will be the only kinds of substances that will cause the signal to stop completely. When this takes place, simply move on and switch back to the all-metal mode and continue on with the search. This means a hot rock has just been identified.

If on the other hand, the signal on the detector amplifies or remains stable, the target merits being checked out. Increase the changeable discrimination control to ascertain the amount of conductivity in this target. This method shows you why it is essential not to prospect with a metal detector that has a predetermined and fixed discrimination control. If the prospector has already practiced using variable discrimination, he will already be aware of the estimated point on the control where unimportant pyrite will be discarded. If there remains to be a positive response after having passed the setting, then it is very likely a non ferrous pocket or vein of conductive ore has been found and it is possible gold has been found.
