[QUOTE="Ridge Runner, post: 396237, member: 3775"] So just to refresh your memory so you don't get it wrong next Time, A High KHz ( being a 30khz to 71khz + ) Machine will work there but a person will have to reduce the Gain a little, but that is not a problem for a High KHz Machine because the high sensitivity of the high frequency compensates for the reduction in Gain and even though running at a reduced Gain they still find the Gold that a mid frequency machine won't see, Most High Frequency Machines will see Gold so small even when set to the factory pre sets that is that small you will need scales with a 0.0000 readout in order to weigh them, The smallest bit I have weighed that registered on the Scales is 0.0001 of an ounce set to the factory pre sets and It did find bits that would not register that it could see at 2 to 3" in a test. Turn your 20Khz machine down to deal with the mineralization and it will take quite a nugget to get a repeatable signal, A mid frequency machine should be able to see bits a lot smaller than 0.1g [/QUOTE]
