Etrac 4.5x7 dd excel five target plug

So i was out today for an hour before church and was trying out my new Detech excel 4.5x7 coil on an empty lot that is very trashy. I got a solid 13-47 and started to get excited thinking maybe just maybe i had a nice one. Was solid both directions and hitting at 3/4 on the etrac depth indicator. I dug the plug as deep as my sampson shovel will go and flipped it over. Stuck the carrot in the bottom and off it went, so i put the shovel back in the hole and pushed another inch and as i moved it sideways i hit something solid. Still not sure what it is but when you scratch it, it is copper colored. Disappointed i flipped the plug back over and decided to sweep the plug again, this time i get a solid 12-43 , so i am like ok and flip it back over and start with the bottom of the plug on one side of the plug i get a small nail and think i know that is not a 12-43. So i after some more searching on the other side of the plug near the bottom i get a clad dime. I flip the plug back in the hole and sweep it again and bam now i get a solid 12-13 , i am like wow and i flip it over again and i find a square tab and good sized nail maybe a half inch apart. That was it when i rechecked it again.

Interesting that the very first signal i got was not mixed or jumping, extremely solid 13-47 both ways. Second time i scanned the plug after putting back was solid 12-43 no jumping , 3 rd time after putting plug back solid 12-13. All that junk was on top of the deepest copper thingy, then the square tab and 2 inch nail on top of the dime and small nail that were below it. I think i am going to like this coil!!
