I am also, primarily, a Beach Hunter and I hunt in Disc (and Silent Search), no notch and very little disc (nickles are way in, tin foil confetti just out)) and I dig every repeatable signal that will climb after I remove a few inches of sand from the top of the target. if, after I remove a few inches of sand with my foot and the signal doesn't improve or if it starts "barking" at me (like a bottle cap or a piece of charcoal) I usually leave it be. If it rises, even if it sounds like a pulltab, I will dig it. I found a white gold wedding set with 34 diamonds that sounded like a pull tab at first, but the signal started climbing and sounding better as I removed more sand. It was pretty deep and the 2 rings were separate and probably on end too, but still close enough together to affect the sound. I will dig practically any signal that rises, unless it is a soda can. You can tell them because they are still loud when you raise your coil up off the ground. When you haul off the junk, you are improving your next hunt on that same section of beach, at least that is how I feel about keeping all the trash until I come to a trash can. Keep hunting with your Sov and you will learn what it is telling you by just the sounds, you don't need a meter at the beach.
