if I balance the vaquero on the negative side it will pick up coins better and on the positive side it will hit on the gold better?
No, but if it is set way too positive, it will start to not see the high conductive range (like silver and copper). Optimal performance for all targets is when the detector is ground balanced to the ground you are hunting. So, start by ground balancing as the manual states or see one of Mike's videos to help get it set up.
With the Vaquero (and several other detectors too), there is a slight offset to the ground balance when it is switched from the all-metal mod to the discriminate mode. Since it is ground balanced in the all metal mode, that slight offset is what Mike is talking about compensating for when he says
"From what I can see with my "V", if I GB neutral, it's slightly positive in Disc mode. GB a bit negative and it,s seems to be neutral in Disc mode. I found Power GB'ing doesn't really do much, for my "V", so I stick to the above methods and it works just fine."
The more mineralized ground you hunt in the more important it is to compensate for the slight offset to get maximum performance. The ground types in New Jersey, where Mike hunts, and in Kansas, are mostly pretty mild, so getting exactly spot on for ground balance is probably not as critical as it is in places such as central Virginia and the red clay areas of the south / south east or in the north west part of the country. The relatively mild ground condition is why you got good results with your fixed ground balanced detector.
Personally, I wouldn't get too wrapped up in getting the Vaquero set perfectly all the time. Set the ground balance and go hunting and see how you do. I'd guess that you will find targets at good depth.
As Hombre notes, the soil is fairly mild in Kansas. Hombre has found a lot of good stuff with his Tesoros!
