Beaches are always replenished. So you never know what you will find. O.C. MD does use a beach sweeper and I don,t find much in the cleaning path. That being said, they don,t clean everywhere. The best tips I can give are:
1. Go 2 hours before low tide to 2 hours after. Sunday mornings or just after a holiday weekend are best. Older stiff may be found after storms.
2. If that is in the morning 6 to 10 A.M. great.
3. Run as hot as you can to get depth.
4. Use a detector with at least a waterproof coil.
5. Get a sandscoop, preferably one for wet sand.
6. Search the wet sand first. Then the just past the dividing line on the dry side. finally all the dry sand, key spots being activity areas, volley ball courts etc. (look for sand castles and depressions).
7. Dig it all, it,s not that hard.
8. Where to go, believe it or not any beach area from Assateague to Cape Henlopen can be good. All beaches not private are OK. The state owned ones have various other rules but can be detected at times.
9. In O.C. just follow the crowds. Finds in O. C. are generally modern coins and jewelry.
Man I get going on about the beaches, I will have to go down there this Sunday come hell or high water!
