Just two days ago I bought a Bounty Hunter Tracker IV from Academy. My goal is to search for anything interesting so I figured I didn't need much in the way of discrimination. I've put a few hours on it and I'm getting to know the machine fairly well. I've been out to my backyard three times and found a lot of stuff. Unfortunately, except for four pennies, a short chain, and a tag for a keychain, it's all absolute junk, mostly pieces of aluminum cans, wire, etc. I went searching with my little brother in my mother's yard which has pennies everywhere. Except for a 1959 though, they were all 1982 and newer. I found a key in my grandparents' yard but they didn't know right away what it went to. Today I bought a plastic (or carbon fiber or some such) trowel. I almost didn't buy it because I didn't figure it would be stout enough in hard dirt, but it certainly fairs well in my back yard and I can lay the metal detector down and wave the trowel in front of it to see if I've scooped up the item. I'm really glad I bought it now. I'm about to try my hand at the lake and see if I can find something more interesting. I lost some jewelry there before so maybe other people have too and I'll be able to find it.
