That's awexome! You're going to have a great time Joe! Get your lunch money saved up to buy a Lesche digging tool straight away, you will regret it if you buy other cheaper diggers first. When you've mastered everything the ACE 250 is telling you, you'll be ready to move up and dig deeper, or switch coils on the ACE 250 and search really trashy sites. Until then don't discriminate too much or you'll actually be missing good targets. Just dig everything except iron and maybe foil depending on where you are, and learn to retrieve targets fast so you can get to digging the next one. Before you know it you're going to be a digging machine and filling your pouch to the hilt in no time.
Happy Hunting!
