Six Inch Megalodon Tooth Found Friday

I found these teeth Friday in about 50 feet of water.  The largest is six inches and the next largest is over 5 inches.  There is a little root wearing on the larger one.   It is hard to describe the feeling of finding such a large tooth underwater.  I can not see anything and am digging blind, then all of the sudden I have a six inch tooth in my hand.   I still can not see it so I try to feel any damage.  I usually want to come up to look at my find then I wonder what is still down there and it makes me want to find another.  It is a good feeling!!
