I'm about to really put some effort into learning my Deus. I'm so used to my F75, I have hundreds of hrs on it, that it's my go to machine. However I really want to learn my Deus. I was reading that the factory preset programs that come on the Deus are set up for European soil and don't perform well in the states. Is this true? I live in Ms we have very mild soil minerals are not a issue. Will I be ok using the factory programs relic hunting? I use the 11" coil.
