Willo & Lordo,...the standard settings are a good start for beginners to the GPX range, especially in milder soil types typically found on the east coast (well, much more east than the G.T. that is...there will be exceptions of course)....
If you need some help with settings in warmer ground, i am able to guide you somewhat, via PM if you prefer...or here, whichever you like.
I'm also sure that some welcome advice will come from Nenad also, as he has had broader experience than I have with the 4K...as have others, i'm certain, but i still currently use mine, when i get the chance to get out that is, and continue to be surprised by my finds....and where they were found.
[edit] P.S. .....pssst, if you got a manual with it, read it, think about what you read for a few days while trying out the Factory Preset settings, then read it again just to confirm your on the right track. I read mine every so often and pick up things earlier regarded as 'not being useful' in my circumstances, so brushed past them. Once your familiar with it, i recommend using various settings even on tried and true ground/settings...
Good luck with your journey....
