Welcome from southern Nevada.
When you get your detector, a good way to learn it is a sand volleyball court. You can plant targets and get a chance to learn the machine.
Pinpointing is easy, but it takes a little practice. Again, the volleyball court makes it easier.
Most carry a hand-held pinpointer too. They help a lot when retrieving a target in a hole and shallow targets just under the grass. If you have one in mind, ask on the forum. You'll get plenty of advice.
Learn to go slowly. This is not a sprint, it's a marathon.
