Your thoughts on digging " Overload Signals"

[Hot zone]

Those zinc lids sure can be detected deep, and seem to be everywhere around these woods, less the shall I say round silver pieces.

Interesting what targets are giving an overload signal for some. I have dug many beer cans and zinc jar lids, but none of them have ever been an overload.

I dug 1 overload, ironically it was a shovel. But not a very old one!!!

My last overload was a water soaked Iphone. The majority of the time it ends up being buried pop/beer cans, but occasionally you will be surprised. I dig all the overloads, just so I can save some ear damage my next trip.

I was in a covered garage with a dirt floor....got an overload signal as a passed over a clump of dirt. I kicked the clump and out came a large circular object that appeared to be some type of coin. It was very dirty and appeared to be rusty or extremely tarnished. My first thought was that the coin was copper or clad and had rusted. My wife is a chemist....and I asked her how to clean the coin, so she took it....and came back a minute later, and said...this coin isn't copper...it's silver. Turns out that it was a 1917 British Half Crown. It turns out that the guy who originally built the house and garage was in the first World War and evidently brought the coin back with him.

With that said...99.9% of the overloads have been plow parts or tin cans but you never know.
