Diggin in GA,
Hi. I don't want to throw water on your metal detecting fire, but in Pasco County there aren't many places that one can go. Almost all county owned land (the citizen's land) is off limits. Schools have big no trespassing signs and they mean it. There are three beaches that one can go to for a limited time (2 hours or something like that) at a specified location. Believe me these three beaches won't have much more than a penny. Private places would be the ideal location.
Most of us from Pasco end up heading south to Pinellas County. I don't know which part of west Pasco that you are heading to but I would recommend to head a little bit south to hunt at one of the beaches. If you are interested in a list of possible good sites send me a message and I'll share with you some good possibilities.
There are many old homes in the area. If your family here knows someone with one maybe they can ask if you could run your metal detector on it. Most people will give you permission to hunt their property if they are nice. Of course if they have a $10,000.00 lawn nothing will work.....
Have a nice time on your trip to Pasco.
