Used to do it quite a bit in my early teens and still have one. I just don't go out much. Started out with a Compass Magnum 320. Had a Garrett ADS 7. Owned a Whites Spectrum for awhile. Currently own a Minelab Safari. The Minelab is awesome on black sand beaches.
I've found lots of old coins. Coolest find for me was an American Civil War cannon ball.
Costco always has the best deal on a decent Bounty Hunter when they have it. The $200+ model is ~$100 at Costco when they are trying to get rid of them. If you want high end, lots of old guys buy an expensive one and get disillusioned with it quickly. There are all kinds of deals on CL and Marketplace.
