There are many easy ways to find good sites to search if you do a little research.
A few of my favorite ways of adding to my secret sites list in Florida are going to postcard, bottle, coin shows, internet property appraisers sites and watching old TV movies / shows for background references.
I have had many multiple gold ring days thanks to taking notice of crowded areas in the background of the 1980s Miami Vice series, areas up and down the Florida coastline that are now totally different.
Postcard shows are easy ways to get a glimpse of what areas looked like back in the day, go straight to the old local postcards and look for crowded areas, beach entrances or swimming holes that are no longer there.
Bottle shows, head to the older bottle tables and you will sometimes hear stories from sellers of where the bottles were recovered or tales of bottle digging.
In Florida I like to head to the tables full of black glass and hear diving stories from old timers.
Coin shows are the same, if you seek out the tables with older coins nine times out of ten the person detected many of the shipwreck coins, it helps if you don't say you search for bottles or coins lol
Property appraisers sites have all the dates houses were built, if you are a beach hunter seek out areas close to the beach and try figure out where old beach access and swimming areas were located back in the day.
Old maps are obviously a great research tool, check out place or road names, I have found many old sites by researching why an area, road or lane starting with the word "Old" got its name.
When you do your research and find areas you often have the area all to yourself to metal detect.
I search many different beaches and stumble on areas that produces coins and jewelry, the area is often off the beaten track away from beach entrances, hotels or parking lots used today.
There is no obvious reason why the coins or jewelry ended up there, but I find out by researching the areas past history.
It almost always end up the same explanation, back in the day the area looked very different to what it does today.
The gold ring in the photo was one of several pieces of gold and silver from the 1950s I recovered a few years back after attending an old postcard show and picking up an old swimming area from a postcard.
If your tired of going to the same places metal detecting, look to the past to move ahead.
