Took the Eldorado to the river where we sluice yesterday to try it out. I have heard of Hot Rocks before but had never encountered one and didn't even know we had them here. Boy was i wrong. We have Lots of them. So how do i adjust for them? I am finally getting the ground balancing figured out at least. Do i just ground balance it over a Hot Rock or what do i do? Or can you get the detector to ignore them? Is there any Gold detector that doesn't have a problem with them? Thanks for any Info, Tips, and Advice.

Now the work begins--you must know "EXACTLY" where your NULL zone is on the unit--up from it your lookn' for non ferrous objects--below your lookn' for iron objects. It's where the detector goes completely silent when slowly pumping the unit from 1"--to 6" off the ground. FIRST though your air adjustment for electrical interference must be performed to bring the unit down to a tiny TINY sound. Never GB to a hot rock as your telling the unit it's the normal ground situation and you will miss at least 90% of the gold--educate and prosper

Anyway,i have a question for ya about the threshold. If i set lit a bit louder during the ground balance so i can hear the difference, and then lower the volume after i get it set is that ok or does that mess up the ground balance? I guess i better bring a few of them Hot Rocks home to experiment with. I do know the Eldorado will find gold. just think i am going to need one with more KHZ and more gain to find the smaller sizes i am interested in not missing.
) and some of the older units still very viable,El D a good example-John
