Where ever people gather. Pull tabs are a indicator that people use the spot. School yards right now are good spots to hunt. Kids are always loosing lunch money, if they aren't yet using credit cards, and the occasionally item of jewelry. Parks are also good spots as well as yours and your neighbors yard, with their permission, for spots to hunt.
Be sure to start off by reading the detector manual. Mainly you will be hunting for coins and coin numbers on your screen reading will be the higher numbers. Throw some coins on the ground and see how each read and sound and do the same with a variety of trash items.
That F 22 is a good detector and if you can get it on a spot that has some coins, it will treat you well. Good luck to you and your daughter. HH jim tn
