My goal has been to keep my detector quiet as a mouse when I go detecting so that I can hear the most tiny ground change that may be a deep target. Most prospectors detect this way but I came across a fellow that had his detector cranked up so high I thought that there is no way that he can find gold, then I had an education.
He was using a modded GPX5000 with the front gain nearly full and the back gain on 20. I thought no way, this guy has lost his marbles but then he showed me a 16 oz nugget he got the day before, then he showed me the pictures on his phone and I was amazed.
