many people i have talked to said in the eastern part of the u.s. the cibola will work just as good anywhere. the part that confuses me is that if you have a machine with a preset ground balance how can it be just as good as one with manual ground balance, there has to be some changes in ground conditions. and i would think having the option to set it manual to the ground conditions you would get optimal performance and depth. Also could you not dial the v or t to a certain point and basically have a cibola like previously mentioned, and at what point on the dial would that be on a v. If someone could also respond inland in florida where there is little to no mineralization where would you set the dial if you can not ground balance because lack of.
