Most beach hunters hit the front 1/3 of the beach most of all. Thats where the people are mostly. For the ocean anyway, thats where the most change takes place as well. Huge surges, wind directions, storms, seasonal tide changes and RAIN eroison likely move more targets around (buries/unburies) than anything else. Most targets will move to their equal weight..... unless stopped by something.... just like in the dirt.
