Thanks, sandman. I will have to find a nice case for this. It's the best thing I have ever found so far. I'm so tempted to pull it out of the wood but I won't. I read there has been makers marks on nails this size. I wish I could go back there today cause I heard other signals around there in the water but just could not get a chance to dig them since I only have a v3i (that can't get wet) and the waves just kept getting bigger; wish I had a PI detector and did not have to work today. Before I found it I could swear I could hear something in the ground shaking and vibrating the ground every time the waves crashed and I tickled the idea that a large wreck in the surf was shaking the ground, then another hundred feet and found the nail. The other signal I got a glance of we're in the led and brass range.
I'm so excited, as soon as I get my boat fixed I'm gonna get out there off the beach and search around
Any idea how old it could be and why half of it is square and the rest is round? Anybody?
