Very well said, and very true! Sometimes I'll pass an open grassy field, with nothing else on it, or, even nearby, but, NOBODY knows what was on that spot, 100, 200 years ago, unless they've studied an older map of an area. So, best thing to do is...
Just get out and swing!!! Let your detector be your map. It'll tell you real quick what the story is, if any. Old stuff coming up? Filled? What era are the finds from? Silver, iron, coins, doo-dads? What depth are items at? It never ends. An endless maze of questions & answers.
I've learned this the hard way, but...
NEVER ASSUME
I've hunted places and have thought, "Nah, ain't no coins in that section"...surprise, there were! I've also hit places where I could almost FEEL the old coins & relics around me, and nada...nothing. One just never knows.
One big thing that's been good to me is, searching under, tightly around, or even in bushes or hedges. Most hunters stop swinging a couple of feet from them, for some strange reason, as if scrubbing the coil of their detector against a few twigs will turn them into a pumpkin. GET THAT COIL UNDER THOSE BUSHES! Work yourself into a little nook or cranny and maneuver that coil around. Get on your hands and knees.
The woods, as you've learned, just like beach hunting, park hunting, relic hunting or gold nugget shooting, is truly an art unto itself.
