I'm leaning towards a Quattro. However the EXII backlight and dual ferrous/conductivity display seems important? I use Excaliburs and recently purchased a Sov GT. If I purchased the Quattro, then I either would keep the Quattro or Sov and sell the other, based on which I liked better in the field. So if any of you have used/own both machines (Quattro/EXII), which do you prefer? For that matter, also Quattro vs Sov GT thoughts. Thanks, Chris.
