All my detecting has been done on beaches. Last night I went up to my Dad's place that has been there for well over 100 years. That Explorer II drove me crazy. Beeping and buzzing. I finally thought I had a good hit about 4 to 6 inches down. I used my new sod corer and found a piece of broken ceramic material that had a gold type glaze on it. And I found that piece about 1 inch under the grass surface, a long ways from 4 to 6 inches as indicated. I hope this long learning curve shortens up pretty soon. It's getting upsetting. I thought my White was complicated. WOW, that was simple. Although I shouldn't complain, last saturday at the beach I was out for a few hours in the morning and 1 hour in the evening and picked up about $6 in change. I'm on vacation next week till Labor Day. I'm going to try and hit a few of the beaches and really try to educate myself on the digital readings and the quick start graphs and hopefully that should make a difference. Wish me luck, I'm needing it.
