You're a sick puppy if you want to fool around with metal detectors. Fetishes are getting weirder by the day in Clown World. Get a girlfriend instead. They're much more fun to fool around with and people generally won't think you're a weirdo for it.

The best tip is, buy the 'best' detector you can afford. There is no end to the lost coins and rings in old abandon yards. My uncle found an 1800s $5 gold piece.

I do when I have the time. I've found a few things. Civil war bullets, horse shoes, old coins around 1830ish. Lots of trash. Get a decent pin pointer and a nice detector. You want a good shovel. There is an awesome YouTuber names Nugget Noggin and another named Klesh Guitars. Klesh also does gold panning. Nugget is really great though very helpful if you are starting, but klesh has info as well, but has gotten more focused on panning now.

My nephews have found some cool old farm remnants at my parent's place.

get a good detector, i use a couple of whites, a goldbug and a spectrum xlt for artifacts. have found several hundred coins, rings, baubles and a ton of trash. nothinng worth much, but it's a lot of fun. a pinpointer (whites} really helps when sifting pay dirt
