I’m hunting in the USA…..I’m wondering how far the discrimination goes on the Vista X ?……I don’t own one …The discrimination on my earlier Vista Gold didn’t go too far in the discrimination range….For example, will it go as high as discriminating pennies ?…. Nickel ‘s ?……One of the best features on my Gold was that I could adjust and hear the iron volume, and you would soon see how good the Gold actually is at unmasking targets….Nothing (and I’ve owned a few ) can touch it…..I’m looking for a little more discrimination range out of the X……Thanks
