I started detecting 5 years ago, 99% of the time beach hunting, wet sand and dry sand only, no water hunting. During this time I mainly zig zag while hunting, and I rarely grid. I just look for areas that look like where people have been, for example: trash, towel impressions, butt impressions, cuts, holes etc.. Nothing scientific or any special settings, I just retired so I go beach hunting daily now and I always find lots and lots of real good stuff, gold, silver, platinum, diamonds, rings, bracelets, chains, necklaces, watches, etc.. I mainly walk the beach (summer or winter time) and then turn around and come back to where I started and I find good stuff in both directions. I watch videos and I read the forums and I hear and see people talk about settings, gridding, tides, deep signals and what sounds to dig. My question, is metal detecting (beach hunting), technique, just luck or both?
