Welcome to the hobby.
As far as hunting goes.....look for old homeplaces, swimming holes, dirt parking lots, or places where people would like to congregate.
For homesites...the first places to check are under the clothes line and where people would get out of their cars.
In non-beach areas, you will find that you have to dig a little more. You will dig up some junk, that's just part of it. Even sometimes the junk is fascinating. Coins almost always give a coin signature signal...be it nickel, zinc, or silver. However....gold can read anywhere from tin foil to silver. You have to determine if you are willing to dig a lot of junk to try and find gold. For me, I dig those signals at the beach, but rarely on homesites.
Start with talking to people you know for ideas and hopefully permission to hunt their property. Ideally you want homesites built before 1960 so there is a strong possibility of pulling a silver coin or two.
Beach digging is a different animal. You really are looking for jewelry, but will take a coin or two.
The biggest thing is to remember to have fun, and to make a few friends along the way. Odds are you won't get rich....but enjoy trying.
