Hi Buzzb,
There are quite a few things, but I'll mention a few that helped me. First, if possible, find a good local dealer who can help you get the most out of your machine and possibly stear you to a few good places to hunt. Also, see if you have a metal detecting club in your area. There you may meet up with some buddies that can help you learn from and probably hunt with.
You should also locate the metal detecting code of ethics and take note of that. Common sense things, like cover your holes, ask permission, close gates when you go through, etc.
After you have a good understanding of your machine, metal detecting ethics, then some bench testing and the use of a target garden will help you know what a good target sounds like on your machine.
Eventually, there will be nothing better than the experience you get in the field. Never stop learning, everything target you dig up will help you find your next treasure. By that I mean that even a pull tab can give you a clue as to what is in the ground and at what depth, where the traffic pattern was, etc. A rail road spike miles away from a railroad might mean the existance of a Civil war camp. Learn from every target.
The main thing for now is to keep swinging your coil and good things will happen. It is just a matter of time.
