Welcome from PA. Enjoy your 540, it will definitely find you some cool stuff. The Pro Pack is a great value too. Don't hesitate to ask questions in this forum, there are lots of good folks with useful info.

IMO - Spend the money on a great pinpointer like the Garret ProPointer AT. You can find inexpensive shovels and serrated digging (garden tools) anywhere, even HD or Lowes.
