What are the differences in the software versions?,and do they weigh the same or almost the same as the XLT? I bought an XLT when whites first replaced the Eagle spectrum with the XLT and found a great many realy neat things with it.The new vision or V3 looks like the new hot ticket.I first thought that when they came out and Whites was'nt letting their dealers sell them on the internet that it would be a long time before you would see any used ones come up for sale on the internet,which has proven not to be the case.Perhaps a lot of people find all of the adjustments scary or confusing.I know that with the XLT a lot of users made no attempt to make adjustments and just used all the factory presets.Whites has allways made quality metal detectors worth every penny new or used.
