Hi Leon and welcome to metal detecting.
As has been suggested first learn how to dig a hole and when you leave it folks can not tell you were there.
In metal detecting for things people have left behind you want to start where they congregated. Picnic table, around shade trees, out in the barn, the standing spot around a corral watching the animals, a swing or swing set, the wood chopping location/pile, any tree that kids/adults could climb as climbing or hanging upside down in a tree tends to empty pockets, jungle gyms and then do not forget the clothes drying line as this is another place where pants are hung upside down.
These should get you started...........63bkpkr
Swing your coil over a target as many times and in as many directions as it takes to locate the center of the target location, usually/in general this is when the signal is loudest.
