Is the VX3 a great detector, YES. But that wasn't the question. If you don't need the features I mention it will do a super job for you.
There is a difference in a few KEY areas. In my modified Hi Pro program with the VX3 I couldn't run zero tones instead of discriminating VDI, I couldn't run in best data, I couldn't block my tones, I couldn't run 5 tones in ferrous and I couldn't have an analysis screen set up with a second filter. The guy I hunt with runs his Hi Pro in 7.5 and the VX3 doesn't have this filter.
The question was does it have differences. Yes there are all kinds of customizing features for the screens, menus, live contols, and colors but they don't really affect performance. I seldom use TX boost but it did help me find a silver 3 pence coin.
