I wonder if anyone has ever heard the pinpoint audio warble - almost like the bell sound you get when the electronics get overloaded on a large object ? I was on the beach today and heard this for the first time - the target turned out to be a hot rock - but it wasn't that big. Then it did it again and this time it was the top of a coke can at about 6 inches deep. Anyone got any ideas on this one ?
