I was going out to hunt and grandson asked it he could come along. A first! I set up the F70 and showed him how to work with it. Showed him the pin pointer and the screwdriver. We set out to hunt. He caught on pretty good. Sometimes it took him more than 5 minutes to find the target but he kept at it. After an hour I asked him if he wanted to go to McDonald's. We went. Here is what he found and dug (or popped out) himself. He is 11 years old, maybe he will want to come again??? Hope so. Of course he wants the coins. I can't even add them to my total of coins. He did a real good job. Thanks for reading...Z
